Replica Review: Tokyo Marui H&K MP5A5 (NGRS)

Duplicate Evaluation: Tokyo Marui H&Ok MP5A5 (NGRS)

Some of us have been ready so lengthy for a Recoil Shock MP5, that when Japan’s ARMS Magazine inadvertently leaked an image of the NGRS MP5A5, we weren’t fairly positive what to imagine; That is in fact till Marui apologised for the leak, confirming that it was certainly actual! But what’s all of the fuss about? Let’s have an in depth have a look at Marui’s newest NGRS design…

Ladies and gents, I current to you, Tokyo Marui’s Next Generation Recoil Shock Heckler & Koch MP5A5.

The Tokyo Marui NGRS MP5A5 comes inside an exceptionally enticing field, surpassing even Marui’s common excessive requirements. A textured black cardboard field with a card coated polystyrene insert retains every part presentable, and firmly held in place. Other equipment and manuals are held both within the lid or inside their very own sections within the field itself.

I received’t carry on in regards to the field or it’s contents, however like with every other Tokyo Marui duplicate, it comes with every part you’d want besides batteries.

The following equipment are included with the MP5A5:

  • 1 x Steel Bodied 72 Round Magazine
  • Tri-Lug Suppressor Adaptor
  • A Pair Of Suppressor Stand-Off Rings
  • Barrel Cleaning/Unjamming Rod
  • Red Muzzle Safety Plug/Cap
  • Drum Sight Adjustment Tool/Driver
  • Motor-Height Adjustment Allen-Key
  • Small Bag Of .20g Ammo
  • Manual/Parts List


The very first thing you’ll discover in regards to the MP5A5 is simply how reassuringly heavy it’s. Weighing a powerful 3.1 kilos (simply shy of 7lbs), it feels rugged and strong but nonetheless by some means refined.

Tokyo Marui have clearly put lots of thought into this duplicate, and it reveals from the second you are taking it out the field.

A single-piece muzzle/sight block provides rigidity to the entrance, placing an finish to the creakiness that’s plagued earlier Tokyo Marui iterations of the MP5. The distinctive MP5 hooded entrance sight is solid throughout the identical block because the aforementioned muzzle, a detachable sight blade is shielded fully by the aforementioned hood.

The NGRS MP5A5 lacks a threaded muzzle, requiring any suppressor or tracer unit to be connected through the Tri-Lug muzzle system. This is likely to be off placing to some, but it surely does add a substantial amount of rigidity to the duplicate and there’s all the time the choice to have your muzzle correctly threaded by somebody who is aware of what they’re doing.

The MP5A5’s Tri-Lug muzzle is designed to work seamlessly with the included Tri-Lug/14mm CCW suppressor adaptor. In my expertise this matches with zero wobble, and really appears to be like fairly good when paired with Marui’s personal tracer unit. To match, merely push the adaptor on, pull the collar again, rotate anti-clockwise about 60° and launch. Once in place, it’s rock stable and simple to take away by easy repeating the earlier steps in reverse.

The entrance hand guard replicates a wider, fashionable “Tropical” design generally used for the reason that 90s. It’s sturdy, it has a unbelievable, uninteresting matt end and regardless of being a undoubtedly boring possibility, it does the job extremely nicely. Many homeowners will have a look at aftermarket choices virtually instantly, but it surely’s good to know that the fundamental handguard is as much as the job.

The physique of the MP5A5 is split into two sections, an higher (metallic) and decrease (polymer) receiver. These are held collectively utilizing a set of physique pins, with the inventory housing additionally offering a further clamp to the rear of the weapon.

The inventory housing meeting additionally incorporates a single sling loop on the weapon’s left hand aspect.

The higher receiver and cocking deal with tube meeting are each constructed from zinc alloy castings, these have been fashioned and completed reasonably nicely, though each lack that chilly laborious end that solely comes with metal.

A fake weld runs across the rear sight meeting and the place the cocking deal with tube meets the entrance of the receiver. These particulars present a completion to what’s general, a reasonably good trying higher receiver.

Note the fake weld line, simply to the appropriate of that is the precise be part of between higher receiver and entrance barrel/cocking tube meeting

The decrease receiver is solely excellent, with Marui going the additional mile to maintain this duplicate as correct in look as doable. The general feel and look of the polymer that Marui have used offers the MP5A5 a very distinctive really feel amongst airsoft replicas.

The width of the pistol grip has been profiled down from earlier MP5 AEG designs to make it nearer in form and dimension to the true factor, the vast majority of that are based mostly upon Marui’s authentic design.

It’s a powerful transfer for Marui to take a look at pursuing a extra real looking design on the expense of ease of manufacture and elevated prices, what’s extra spectacular is that it homes the identical dimension lengthy shaft motor as a full sized AEG.

Moving onto the controls, there’s merely nowhere higher to start out than the charging/cocking deal with. You may very well be forgiven for being disenchanted once you first see it, the charging deal with being of plastic development and sitting inside a zinc-alloy meeting.

Whilst the charging deal with may not present a fantastic first impression, it seems to be totally as much as the job it was created for and regardless of my higher judgement, the charging deal with has been slapped so laborious and sometimes that it’s began calling me step bro. I’ve routinely checked it for put on/harm and located nothing untoward, regardless of slapping it prefer it owes me cash.

Note the hop adjustment accessed through the open chamber, clearly labelled for morons like me.

One of the largest surprises of the entire design is the hearth selector, it’s unbelievable. I’m genuinely blown away by the way it feels, with Marui shifting away from the exterior detent and pin selector design, they’ve developed an inner design for the MP5A5 that gives a really optimistic and extremely satisfying click on, while being far stronger and fewer liable to put on.

The absolutely ambidextrous selector makes use of a set axle going fully by means of the gearbox, offering a reassuringly optimistic really feel to each the left and proper selector switches. Being a left-handed shooter, I have a tendency to reveal the weak point of poorly designed ambidextrous selectors reasonably shortly. However, this selector doesn’t seem to endure from a proper hand biased design.

The journal launch is the normal MP5 paddle design, and comes with the button sort launch that nobody of their proper thoughts ever makes use of. The paddle sort launch is intuitively straightforward to make use of and is completely rock stable as soon as the journal is seated, the button launch is realistically painful to make use of and needs to be left nicely alone.

The set off isn’t like these discovered on most different MP5s, it’s closely sprung and supplies a reasonably sturdy resistance to the pull. A micro change on the M-System ECU offers you a delicate however constant firing level, with solely a few millimetres of journey wanted.

Ultimately, the set off works nicely and supplies a novel, mildly haptic suggestions, though I’d have preferred to have seen a fake sear launch as Marui beforehand used on their Mk46 Mod 0.

It has been stated, iron sights hit peak perfection with the MP5 design. The hooded entrance sight marries up completely with certainly one of 4 round apertures throughout the rotating drum, permitting the shooter’s eye to naturally place the blade itself onto the goal.

The drum just isn’t designed for various ranges (as some video games may need you imagine), it merely supplies 4 sizes of aperture to permit for particular person shooter’s eyesight wants. The concept is that it’s best to use the opening that permits the smallest quantity of sunshine across the exterior of the entrance ring, to permit your eye to naturally align the sights accurately.

An MP5 sight image exhibiting good alignment, with a fair halo of sunshine across the entrance sight hood and the purpose of impression at 25m being simply on high of the entrance sight blade.

The drum can also be adjustable for windage do you have to want it to be, though this isn’t one thing you’d need to be doing out within the discipline because it requires instruments. Ultimately, it’s solely there as a result of the true one has it.

Note the safety wings on the aspect of the rear drum sight.

One of the largest surprises in regards to the Marui MP5A5 is it’s sliding inventory, particularly how rugged it’s! It doesn’t rattle or wobble round when in both place, and slides smoother than farting by means of silk.

The inventory design replicates the older, non-padded telescoping inventory design (which I desire). The inventory has solely two positions, absolutely prolonged or absolutely closed. Heckler & Koch do make each a two or 4 place sliding inventory, however this design can also be my most well-liked selection on account of it’s simplicity.

When absolutely retracted, the inventory bars slide alongside built-in channels on the aspect of the MP5A5, these additionally present a further diploma of rigidity to the firearm as a complete.

A metal bodied journal makes an fascinating addition, boasting a 72 spherical capability and switchable internally to an actual world capability of 30 rounds. The internals of the NGRS MP5 journal are much like NGRS M4 magazines, with a lower off lever to cease the duplicate firing when the journal is empty. Sadly although, you’ll have to offer your individual pink tape.

The seesaw latch prevents the follower from shifting previous a 30 spherical capability if that’s the case desired.


As this can be a Next Generation Recoil Shock mannequin, you’d be right in considering that the internals are reasonably totally different to earlier era MP5 fashions.

The barrel and hop use Marui’s current AEP design… Yes, you’ve learn that proper; AEP as in Airsoft Electric Pistol. Rumours are that Marui contemplate this to be their greatest general hop design, with it providing good efficiency in a compact bundle. It’s price noting that the Mk46 Mod.0 additionally used this hop design and I’ve personally not had any complaints about it’s accuracy or vary, I’d additionally put cash on future NGRS builds utilizing the identical hop design.

The brass interior barrel is a full 229mm, with an inner bore of 6.08mm. I’m a fan of brass barrels basically, and Marui’s barrels in my expertise supply a really constant and easy end that’s laborious to beat.

Note the profile of the barrel, profiled to a naked minimal to help in becoming batteries throughout the MP5A5’s ahead hand guard.

At the center of the NGRS MP5A5 is the M-System Electronic Control Unit (ECU). The M-System’s identify is derived from it’s use of magnetic switches which can be used to manage the hearth selector mode, and for sensing when the cocking deal with is within the ahead place. There is a component of mechanical ingenuity to the design, which additionally helps preserve the general really feel of the duplicate suitably rugged.

This system incorporates a micro change activated MOSFET sort set off, with an ECU (digital management unit) controlling all the duplicate. Put merely, a MOSFET geared up ECU is a gateway that opens and shuts with none mechanical limitations, successfully permitting full electrical present from the second the change is pressed. It additionally comprises a micro processor that controls sure actions equivalent to motor spin period, and supplies plenty of helpful options throughout the duplicate’s design equivalent to three spherical burst and cease on empty.

What does this translate to for the typical person? Well… No extra corrosion or arcing on the set off contacts (as a result of they merely don’t exist) and a a lot better set off response time because of the MOSFET set off management offering full present, instantaneously. The M-System additionally seems to have cycle completion in-built, that is reasonably vital because of the gearbox itself not possessing an anti-reversal latch.

A dry fireplace mode can also be out there for testing or theatrical work. To use, merely rack the cocking deal with again 3 times and the duplicate will proceed to fireside, even with an empty journal. To deactivate this characteristic, merely rack the cocking deal with one other 3 times or disconnect the battery.

A blue gentle signifies that the duplicate is in dry fireplace mode.

The wiring on the M-System loom terminates onto an MR30 micro connector, it’s an uncommon selection thats not often used exterior of RC plane however one which works nicely sufficient. The provided MR30 seems to be a real AMASS connector, rated as much as a relentless 30A draw (Mini Tamiya is 15A, Deans is 60A).

An adaptor for the MR30 connector is provided, though I’d change it from Mini Tamiya to Deans at first alternative.

Upon inspection, the hop unit seems shut in design to that used within the NGRS M4 collection. Adjustment is completed through a drum accessed by means of the open ejection port, with the drum offering a safe adjustment that’s each straightforward to make use of and never liable to drifting.

The hop will fortunately elevate .28 ammo, with .3 ammo being lifted however falling brief just a little faster than I’d like for woodland video games. The hop unit can also be connected to the entrance of the gearbox shell, which ought to help with a constant air seal.

With the charging deal with held to the rear, it’s straightforward sufficient to regulate the MP5A5’s hop unit.

The journal design is proprietary, but it surely has echoes of the unique NGRS M4 design. It makes use of the identical mechanical cease on empty lever, though it’s straightforward to see Marui have seemed to enhance upon their older magazines once you look inside.

No seesaw motion on the cease on empty, the lower off is a direct and easy upwards motion.

The gearbox shell has plenty of nicely designed options, making this one of many simpler designs to work on. The wiring may be fully faraway from the surface of the gearbox, with function construct channels with in-built retention clips offering ample routing for the wiring loom.

The entrance of the cylinder window has additionally been “radiused” to stop stress on this well-known weak level of AEG gearbox design.

Will this permit stronger springs for use? I’m not satisfied. But it reveals that Marui are taking steps to delay the lifetime of this new gearbox design. Either manner, it prices nothing and provides power; An general web win.

Note the radius lower into the corners close to the rear of the brass cylinder, serving to cut back the wear and tear on a pure weak level.

The most eye opening revelation internally is that the MP5A5 lacks an anti-reversal latch, the element on most AEGs that forestalls reverse journey of the gear prepare. What does this imply for you and me? Well, should you’re seeking to construct a duplicate that has instantaneous set off response, an AR latch is a crucial element for pre-cock enabled ECUs.

Without an AR latch, the spring will merely spin the gear-train backwards till the spring reaches it’s absolutely decompressed place. Does this imply that corporations like Gate and Black Talon Concepts are unable to provide a characteristic loaded ECU?

Well, if Marui have been straightforward to supply spares from, I’d really say there wouldn’t be a lot level; As inventory, that is arguably essentially the most characteristic packed management system in the marketplace. But given Marui’s observe file with spares, I’d prefer to see a extra rugged aftermarket possibility made out there.

Black Talon Concept’s Spectre ECU revolutionised the NGRS M4 platform, and I’d like to see the identical assist given to the brand new MP5A5

Aside from this, the gearbox appears to be like reasonably like most different NGRS fashions. The cylinder/head, piston meeting, spring and gear-train are all NGRS V2 (M4/416)suitable. Other elements look like proprietary, however the spring information is seemingly shut sufficient to a V3 (AK) for it to work.

The recoil weight is positioned above the gearbox, as per their NGRS G36 and AK designs. Weighing round 300 grams and lengthening in direction of the entrance of the duplicate, it helps give the MP5A5 a noticeable judder to it’s fake recoil. The recoil operation is reasonably brief in stroke, utilizing a rack and pinion design to double the journey of the ejection port cowl when in use; Another intelligent transfer by Marui.

A normal sized Marui EG1000 V2 lengthy shaft motor is housed throughout the pistol grip, making upgrades a future risk. Although I’d advise ready till an appropriate ECU is obtainable as a number of homeowners have already fried the inventory M-System ECU by swapping out to larger torque/brushless motors.


External compatibility continues to be very a lot trial and error. I’ve seen lots of extraordinary stuff fitted to NGRS MP5A5s, however keep in mind that one guys concept of how a rail ought to match is likely to be totally different to yours. One man’s wobbly rail is one other man’s “thats adequate”. Eagle 6 are providing a few pre-modified choices, however for these seeking to do it your self, you’ll need to preserve your self knowledgeable of what the NGRS MP5 group is presently trialling.

I’ve personally discovered that VFC clones of the SureFire 628 Lighted Fore-End and the Knight’s Armament Co. MP5 RAS match exceptionally nicely. The solely modification that I’ve carried out on the Surefire clone, is the removing of two inner ribs to permit just a little extra battery house. The KAC is cavernous, though most batteries might be seen throughout the RAS except rail covers are used.

This is getting out of hand, now there are two of them!

Looking at optic mounts, G&G low profile AEG claw mounts appear to be the perfect finances possibility, and are rock stable in addition. Real mounts have been stated to suit completely, or don’t match in any respect relying on who you converse to. Again, please remember that becoming to private acceptance isn’t all the time indicative of one thing becoming accurately.

Stocks are one other space of conflicting info, some say each VFC and actual full physique shares match, others say that they want just a little work. As with any second hand info, I usually deal with it with a level of scepticism. Anything may be made to suit, it’s normally a query of time, cash and/or competence.


Performance isn’t a straightforward metric to quantify, however finally it’s the one one which issues when stacking it in opposition to the competitors. Previous NGRS fashions have set the bar reasonably excessive, however can this revolutionary design stay as much as it’s senior brethren?

Well, let’s begin with the great things: each vary and accuracy are par for the course for a Marui NGRS duplicate. I despise placing an precise quantity on most vary, however I’ll confidently say that utilizing the MP5A5 in open woodland didn’t go away me feeling outgunned in opposition to your common airsofter.

FPS smart, it websites round 260 with .25 ammo (0.8 joules), placing it comfortably below the UK restrict, however not precisely gutless. With just a few tweaks, I’m positive it may very well be pushed near 1.1 joules with out important hassle.

The really feel and sound of the MP5A5 firing can also be just about precisely what I wished it to be. The set off response is excellent, though not fairly the bleeding edge launch that I’ve come to anticipate from a pre-cocked Gate Titan/BTC Spectre geared up NGRS. The price of fireplace can also be reassuringly speedy, at a weapon right cyclic price of round 800 rounds per minute.

So why did the assessment take so lengthy? Well, the reality is that I kinda broke my first MP5A5. Not fully, however definitely sufficient to trigger just a few points. Despite the wonders of the web and Marui even placing a skinny pink stripe on one of many wires to mark it as optimistic, I nonetheless managed to wire up my Lipo backwards.

It was solely linked for just a few seconds, however the harm was quick. My solely indication that one thing was incorrect was an acrid odor of ozone, and the uneasy heat coming from the motor and battery. This precipitated me to lob the Lipo out my window like an M67 frag grenade. Another £12 down the drain.

I rewired it immediately, however after a number of months of intermittent points with the primary MP5, I bit the bullet and purchased a second one simply to verify it was me and never the duplicate itself that had precipitated the problems.

The points attributable to the reverse-polarity mishap have been the next:

  • Double feeding
  • Misfeeding
  • Unwinding sound after every shot

Whilst it may appear psychological to purchase a second duplicate with out realizing if it was the duplicate or me at fault, I felt on the very least that it wasn’t proper to finish a assessment till I knew for sure that the problems I’d suffered from have been attributable to me, and never a symptom of dangerous design.

But how precisely may just a few seconds of reverse polarity trigger such points? The M-System ECU makes use of plenty of FETs inside it’s board, the important thing ones getting used to manage the first motion of the motor, however others are used to help with the cycle completion. The M-System additionally seems to make use of preset energetic breaking, which given the shortage of an AR Latch is important to making sure that there isn’t any rearward spin on the gear prepare.

By connecting the Lipo the incorrect manner, it’s seemingly that I’ve broken the FETs accountable for controlling energetic breaking, inflicting the over-spin and rearward motion that I’m seeing and listening to on my MP5A5. In truth, I can see that one of many diodes is cracked, seemingly inflicting the problems I’ve seen.

Note the crack working by means of that black block, a positive signal of injury.

How does this translate into double feeds and failures to feed? Probably again stress and nozzle/tappet timing; When the gear set over spins, it causes the rearward motion of the piston. This rearward spin causes the nozzle to maneuver again out the way in which after chambering a spherical, permitting a second to be fed into the hop unit or typically pulling the initially chambered spherical again out.

I’ve additionally observed that my first MP5A5 has considerably of a stiff journal nicely, one thing that isn’t current in my second buy. This is also contributing to a number of the points, though virtually everybody else I’ve spoken to doesn’t seem to have a difficulty with theirs.

To date I’ve put round 9/10k rounds by means of my first MP5A5, and an additional 2k by means of the brand new one. The issues have been constantly current with the primary one however non-existent with it’s substitute. After in depth use with the second MP5, I’m pleased that the difficulty was attributable to me, and that there doesn’t look like a systemic difficulty with the design.


The NGRS MP5A5 is Marui’s new flagship mannequin, and one which has been welcomed with open arms by the group. No different duplicate has been so hotly anticipated, eagerly pre-ordered or offered out as shortly because the NGRS MP5A5, with in my estimation round 200 items offered within the U.Ok. alone on their preliminary batch. Did Marui anticipate it to be so fashionable? in all probability not, however whether or not its the worldwide scarcity of microchips or another cause, theres one darkish cloud that has overshadowed it’s launch.

So far, elements and spares assist has been nothing in need of surprising. Despite the MP5A5 being arguably Marui’s greatest success from launch, they’ve did not manufacture sufficient magazines to maintain up with demand. There’s additionally not been an enormous push for aftermarket elements, one thing that finally left the Mk46 Mod 0 in a class of “I’d love to make use of it, however I’m shit scared to interrupt one thing I cant substitute”. But the NGRS crowd are usually fairly pleased to spend cash on elements or upgrades, with the vast majority of NGRS homeowners having at the very least one or two modifications to their inventory duplicate; one thing that we will solely hope is met with enthusiastic assist by elements and spares producers over the approaching years.

The Mk46 Mod.0, Marui’s biggest achievement? Or its greatest failure? It all relies on the context.

It’s been greater than 6 months because it’s launch, and lots of potential patrons nonetheless can’t pay money for one. And these that may, may not be capable to discover sufficient magazines to truly discipline it. I’m conscious of the irony of me having used mine from launch and having purchased a second MP5 in addition, however I simply occurred to be in the appropriate place on the proper time.

I do know of three different patrons inside my circle of mates who’ve an NGRS MP5A5 however don’t have any spare magazines. Despite utilizing mine since launch, I’ve not seen anybody else carry one to a recreation. So far, this duplicate is woefully underrepresented within the discipline, and with out magazines and elements assist it should by no means stay as much as its potential.

Will elements assist choose up? I hope to god it does! Because if one thing proprietary breaks (such because the M-System ECU), you’re going to be left with a 500 paperweight. So far, theres just one improve out there for the NGRS MP5A5; an interior barrel made by Laylax. Quite frankly, that’s not sufficient to assist the client base. Unless we see a ruggedized improve for the ECU as a naked minimal, It’s going to hamper the skills of their buyer base on how far they’ll push the efficiency of this duplicate.

Final Thoughts

We’ve now come to that inevitable a part of the assessment, the half the place the one query that basically issues will get answered; Can I like to recommend the Marui NGRS MP5A5 or not?

Well, I did purchase two of them!

Overall, the NGRS MP5 is a reasonably cool little bit of package. If like me, you’ve been bitten at an early age by the MP5 bug, it’s just too fascinating to withstand. It has plenty of options that make it much more immersive in use than it’s rivals, a useful cocking deal with, cease on empty and three spherical burst; Quite merely, it’s essentially the most characteristic packed MP5 you should purchase.

As for worth? It’s going to price you £650 for a gun and 4 mags (or thereabouts). Haters will say {that a} Cyma can shoot higher for much less cash; But it received’t contact the Marui from inventory, and no amount of cash gives you the recoil, cease on empty and management options that the Marui comes with out the field.

It’s nearest rival is arguably the Systema TW5; a duplicate that prices twice as a lot, nonetheless has no recoil and is more and more laborious to search out. This places the Marui NGRS MP5A5 in a novel place, one which in my view is difficult to beat. All in all, a fantastic addition to any assortment.

If you’ve made it this far, thanks for studying. Both replicas have been bought at full worth from Eagle 6 and Airsoft Direct respectively. Thanks to each for his or her service and particularly, Rich at Eagle 6 for the recommendation and assist concerning the problems I’d been having with the mis-feeding.
