PKM machine gun replica - Polymer stock [A&K]

Received mine last week and am happy to say that it performed very well.

The box mag insert is the new "black turbine" model which is WAY more reliable and performant than the old "green" ones.

All of the screws, grip and stock are well tightened with no wobble, creaks or movement at all.

Wiring is well done, no cracks or tearing in any of the shielding.

I did have to "shim" the hop-up nub as it was having issues hoping over 0.25 BB's... but this was trivial and rather common on A&K MG hop ups.

With a 7.4V Titan battery, the ROF is ~13-15 (depending on what chrono brand I used). An 11.1V Titan battery yielded a ROF of ~20.

The air seal seems consistent with the targeted FPS varying by a maximum of 5fps.

I did remove the ROF control board as I have no need for it. It is a very easy process as A&K provide a bypass in the box.

I played a weekend skirmish and shot close to 15000 rounds with no issues. The PKM ran flawlessly.

I did have to change the spring to a 100m/s one to achieve 0.95-0.98J (Ireland has a 1 Joule limit).

In testing, a 110m/s spring yielded ~1.2J and the stock spring was regrettably useless, only providing 0.5J.

The above had the hop set for 0.25 BBs.

I've had great success with A&K Machine guns, using them exclusively for well over a year now. They have worked well in both cold rainy weather and on humid hot days. They survived Milsim use as well as Skirmish days only needing general maintenance/cleaning.

I can recommend this PKM (and the wood furniture model) with no hesitations... as long as you can lift/move with them, give them care and use high quality BB's. these will treat you very well!

I received my PKM two weeks ago. And i am very disappointed a total waste of money!
I have many problems with this replica and now i am trying to fix it!
First it came without one of the screws that holds the gearbox.
Second on the first use the ROF stoped working so i used the plug included it the box and the replica started working.
Third on the game the fuse blown and gears jammed i removed the fuse and unjammed the gears.
Fourth it shoots VERY inconsistent first 2-3 shoots are 1.7j a then starts shooting below 0.5j!
Fifth the gas tube/block is VERY wobbly it's annoying.

Amazing replica, without doubt a perfect PKM, as stock it shoots and behaves above what i thought. I had mine for a skirmish, just amazed how 5000bbs are used so fast. Barely needs any upgrades for niw, but will upgrade soon with taiwan parts
