Matrix PKM Russian Battlefield Squad Automatic Weapon Airsoft Machine Gun by A&K (Furniture: Real Wood)

"To add: This piece of equipment will give you the aggressive SAW look but without the weight like the M60 and MK43 series. The gearbox is A&K's newest version that seem to work smoother too (I also have an A&K M249 Paratrooper.) If you are looking for superior fire-power and a squad automatic weapon, look no further!!

"Just got my PKM last week and had a blast last weekend!!! All in all, the gun works flawless and as expected. It came in a Matrix labeled box with manual, box magazine, battery and charger. I would highly recommend using a lipo!

Pro:
Insanely accurate.
The box magazine works like a charm.
Amazing rate of fire and fire-power.

Con:
None!!

"The PKM is not for the faint of heart. This absolute beast of an AEG is by far my favorite in my arsenal.

Pros:
Accurate, long barrel means bbs hit where needed and sometimes too good
Reliable, so far I've put it through a decent beating and it hasn't bogged out
Intimidation factor, bodies WILL hit the deck

Cons:
Weight, handling this gun fully loaded and geared up is not for the faint of heart
Length, definitely a hindrance in closer quarters

"This thing is without a doubt, the most intimidating gun I have used in a game. It's monsterous in both size and firepower. 5000 rds of hell. ~4.5 feet of hell. 23 ibs of hell. This gun is seriously something from hell. People fear being on the other end of the barrel. People praise you being on their team. This thing is a solid work of metal and power. Never have I experienced the amount of attention I get when I bring this gun to the field. Eyes immediately turn towards you and at times it gets uncomfortable. But oh well.

Pros:
-Big, Huge, Monsterous
-5000 rds
-Fire rate on 9.6v intellect is plain evile with 5000 bbs
-Eye catcher and moral booster for your team
-Sends people running, I am not lying
-I am 6"3' and I can shoot this like a rifle semi comfortably
-All metal except for motor grip, carry handle, stock
-Definite fear factor

Cons:
-Big, Huge, Monsterous (high chance of bumping people, rocks, trees, and getting snagged in bushes)
-Fire rate thing sucks, comes witha bypass plug which I used
-Eye catcher, bound to make you public enemy #1
-Heavy, sling is a must
-Chews through 9.6v before ONE mag is even done!!! Bring a spare... Or get that 10.8v 5000mah which I am thinking on doing
-Bipod fell of during a game because those screws that hold it in are terrible. I lost the bipod because I was running to cover a weak side that was getting flanked and it fell sometime in between. Sucks for me but beware the bipod
-Big, Huge, Monster- Oh wait I already said that it's Big, Huge, and Monsterous didn't I?

And as the couple of reviewers below me stated... People really don't know what this gun is. I almost didn't want to believe that until a group of people actually asked me if this was a modified M2 Browning...... Yes!!! This is definitely a hand held 50cal machine gun!!! No... Not even. A custom 240? No. SVD? Nah man. M249? ... No (I have a CA249 para as well...) What is it?!?! A PKM...

"First off, I'd just like to say this gun is amazing. It is more accurate, gets more range, and with the right battery, shoots as fast as custom guns do. I recommend buying the 10.8V 5000 mah SAW battery, as that will sustain a whole box magazine of 5000 rounds. The only thing is that the SAW battery sticks out of the box mag, so you'll have to buy the dummy 7.62 rounds to conceal it. Out of the box, it chronos around 450 FPS with 0.2s, so it's recommended to buy a lower compression spring. It shoots at around a thousand rounds per minute with the SAW battery, and when it does, people will go running. I've seen it first hand. This is the perfect gun for yourself or a squad. It will really get you out of trouble with no problem. Now for the pros and cons:
Pros:
-5000 round box mag
-everything is metal except for the carry handle, motor grip, and stock
-built-in removable bipod
-rof adjustor (but be warned, if you use more than an 11.1V battery, you will have to remove the rof adjustor)
-looks awesome and intimidating
-extremely long barrel = plenty of range and accuracy
-easy access to internals
-carry handle's swivel makes it more balanced and easy to carry with one hand
-sounds awesome when firing
-easily upgradable
Cons:
-the bipod spin catch can get easily stripped
-orange tip is harder to remove than your normal AEG
-recommend purchasing the reinforced trigger switch because if you hold down the trigger for too long, it will be stuck firing, which you will have to repeatedly pull the trigger to stop it
-no rail system for optics
-no rear sling attachment (I attached mine around the top of the stock)
-weighs 23 lbs., but with a good sling you should be fine
-awkward to fire standing up, but you shouldn't be firing while standing to begin with. This gun is more of a mount on barrier or ground and fire, like SAWs are supposed to be used.
-rof adjuster is where you would hold it if you were standing and firing, but like I said, that's not what it's meant for.
-like someone else said- not many people know what it is. M240? No. SVD? Nope.

All in all, it is definitely worth the buy. You will dominate the field and be feared.

"First off, I can tell you this is my new favorite gun. I can say that I took advantage of the 4th of July 23% off deal and I can tell ya, I couldn't use it until recently at a Big Op, where I learned that the FPS really was around 450, not the listed above, but either way, it definitely fits the role of support gunner. With it, I held off in a bunker against enemy forces for a total of 4 hours, which the only reason I lost the hill was because the battery died. This hit HARD, people from other states said they were happy not to go against it.

Pros:
Great (adjustable) ROF
449.5 FPS (To be exact)
Intimidating as heck (In favor of other profane words.)
5,000 Round Box Mag (With an accumulated total of 8 minutes continuous, suppressive fire)
Hop up is adjustable (That should be a given)
All steel construction (Cept for feeding tube in magazine, handles and stock)

Cons:
Heavy (23 LBs)
Battery drains slightly faster with auto-wind (So buy an extra one)
Little stiff on bipod preparing
BBs have a chance at falling below the feeding mechanism (The 3 screws on the bottom can help with that)
The orange tip is plastic

Other than that, it's all good and PERFECT for a support gunner role.

"Very worth it, not that heavy to where you cant shoulder fire it for long periods of time, price is great if it were any lower every casual would have keep it high bros /)

also the rate of fire adjuster doesnt work all that well. bypass with 14v lipo 2 full box mags day one, flawless.

"Had this gun since April and I can say that this is a pretty good gun for the money. I've never had a problem with this gun and it's very fun to use.

Pros:

Accurate
Don't have to downgrade fps to use at my field!
Large, automatic winding magazine
Almost all metal (really good plastic for pistol grip, carrying handle, and stock and can be replaced with wood!)

Cons:

The RoF selector buttons are where you would put your hand if you were to fire from a standing position. But this gun isn't really meant to be fired from a standing position anyways.

Overall money well spent

"I gun a few days ago and it is HEAVY its difficult to play in a 3 hour war with the PKM. I also had a problem with the box mags latch coming undone and me loosing around 4000 BBS but I fixed that. But overall the PKM is the most intimidating weapon on the battle field and one of the best weapons on the battle field. Also the bipod is very wobbley which isn't a big deal. THIS GUN IS THE BEST GUN IVE EVER HAD!

"First off I love my PKM, he is a beast. Love the box mag with its direct feed, runs off the same battery as the gun, has different feed modes. Its a pretty solid gun, gets decent range. Sadly I'd recommend picking up the reinforced switch they are selling, mine went out pretty quickly, luckily it's really easy to switch out. They say it fires between 340 and 390 fps, thought I'd be ok to take it to an OP but when it chronoed he fired pretty tightly around 450 (impressive but about 50 fps over the allowed limit for saws).
In the end the only real issue I had was with the switch burning out and causing the PKM to continuously fire. Defiantly pick up a spare switch.

"Simply Awesome! Buy it! You will not regret it! Best Airsoft machine gun I ever own!

"To add: This piece of equipment will give you the aggressive SAW look but without the weight like the M60 and MK43 series. The gearbox is A&K's newest version that seem to work smoother too (I also have an A&K M249 Paratrooper.) If you are looking for superior fire-power and a squad automatic weapon, look no further!!

"This gun, out of the box, was completely unfunctional. The trigger would not activate the motor or fire the gun. The box mag would wind, but no pew. A bit disappointing, but considering I had already swapped the muzzle device, voiding the warranty, so nothing i can do in terms of return/swap. I modify all my guns heavily, so this gun was already going to be gutted, but having no function OOTB is disheartening. The externals are great, the wood is nice. Only external issue is the carry handle will not lock properly, the metal mount having already been broke upon my receiving it. Its not to serious as if you slightly adjust the angle of the handle its fine, but still not great. I'm gonna rewire it and do barrel and motor swaps so it will work, but the QC is crap. Never had a gun be dead upon arrival. I'm sure its a lemon, but be aware. Its sexy as **** though. Once functional it will be the perfect addition to my Ukraine kit. No other complaints.

"It seems like A&K quality control has improved somewhat since the inception of the PKM into the airsoft market. I'm referring to the warped gearboxes and aftermarket parts incompatibility that plagued early owners.

I thought I'd post what I've learned and what has worked in my PKM so that new owners can have a parts list to work with.

Parts List:
Barrel: 6.03 Madbull Black Python V2 509mm

Hopup Bucking/Nub: Madbull Red Shark 60 Degree Bucking

Hopup Chamber: Bullgear PKM/M60 Hopup Unit

Magazine Insert: Bullgear PKM Insert

Nozzle: Lonex POM M4A1 Air Nozzle (21.3mm)

Cylinder Head: SHS V2 Cylinder Head

Cylinder: ZCI "Anti-Heat" Stainless Steel Full Cylinder

Shock Reduction: 1/8" 70D Die Cut Neoprene Buffer

Piston Head: Lonex POM Ventilation Piston Head

Piston: SHS 14.5-tooth Full Metal Rack Piston

Gears: Rocket Airsoft 17.28:1 High-Speed Steel Gears

Sector Delayer Chip: SHS Sector Delayer Chip

Shims: Prometheus 24-piece Steel Shim Set

Motor: ASG Ultimate 22TPA CNC Short Motor

Spring: Guarder SP120 Spring

Notes:
LEAVE THE DANG TAPPET PLATE ALONE! The stock one is perfectly fine, even though the color looks kind of weird.

The stock wiring sucks. Simplifying the wiring harness is no monumental task, provided that you're handy with a soldering iron and some heat shrink.

With the Guarder SP120, I'm getting right around 1.5 joules. With the SP130, I get 1.8 joules.

My PKM was the first AEG I've ever worked on myself. I taught myself how to do so by using Chupacabra Outdoor's YouTube videos on AOE correction and how to shim.

Every screw on this gun will loose and back itself out eventually, and I really do mean every screw. You can really save yourself some headaches down the road by using a bit of blue thread lock to keep those pesky screws in place.
