Primary Weapons Systems took the AR platform and gave it the piston treatment, and the MK116 Mod 2-M in 7.62×39 is a great example of what that gets you. This is a complete upper running the PWS long-stroke piston operating system, which keeps the hot gas and carbon up front instead of dumping it back into the action. The payoff is a cleaner running gun, smoother recoil impulse, and a 3-setting adjustable gas block that lets you tune the rifle for suppressed shooting or dirty ammo. The 16.1-inch barrel wears a 1:10 twist that handles the wide range of 7.62×39 loads out there without fuss.
Everything here is built to a high standard. The upper receiver is forged 7075-T6 aluminum with a Type III Class 2 hard-coat anodized finish, and PWS ditches the forward assist for a cleaner profile. Up front sits the 15-inch PicLok free-float handguard, a slim 1.7 inches wide, so you can mount M-LOK accessories or clip Picatinny sections right where you need them. It's a thoughtful setup that keeps the rifle light and lets you run lights, lasers, and grips without a bunch of adapters.
This is a complete upper, not a stripped receiver, so it ships with the bolt carrier group and a Radian Raptor ambidextrous charging handle already fitted. That ambi charging handle is a genuinely nice touch for lefties and anyone who runs optics that crowd the standard latch. A capped muzzle device comes installed to help tame blast and keep things comfortable at the bench or in the field.
The MK116 Mod 2-M is machined in Boise from PWS proprietary forgings and designed to fit and align with most standard AR-15 lowers. Slap it on the lower of your choice, run a magazine, and you've got a piston-driven 7.62×39 carbine that shoots soft and cleans up easy. For anyone who wants the reliability reputation of a piston gun without building from scratch, this is about as straightforward as it gets.
Yes, it's designed to fit and align with most standard AR-15 lowers. PWS machines these from proprietary forgings held to tight tolerances, so it should mate up cleanly. Keep in mind it feeds 7.62×39, so you'll want magazines made for that cartridge.
The piston keeps hot gas and carbon up at the front of the barrel instead of routing it back into the action, so the gun runs cooler and cleaner than a direct-impingement AR. Recoil tends to feel smoother, and the 3-setting adjustable gas block lets you dial it in for suppressed use or dirtier surplus ammo. It's the same operating system PWS owners have relied on for years.
It does. This is a complete upper that ships with the bolt carrier group installed along with a Radian Raptor ambidextrous charging handle. You just need a lower to have a running rifle.
It rides on the PWS PicLok 15-inch free-float handguard, which combines M-LOK compatibility with PWS's PicLok slots. That means you can mount M-LOK accessories directly or add Picatinny rail sections where you want lights, lasers, or hand stops. At 1.7 inches wide it stays slim and comfortable to grip.
