Pws Mk116 Mod 1-M Upr 16" 762X39 Blk$1,136.21
Availability: In Stock
The Primary Weapons Systems MK116 Mod 2-M upper receiver in 7.62x39 is a complete, ready-to-run upper for shooters building or upgrading an AR platform rifle in one of the most practical intermediate cartridges available. Built around PWS's proven long-stroke piston system, this 16-inch upper delivers reliable operation in a compact, configurable package that works equally well for hunting, home defense, or precision shooting.
What sets the MK116 Mod 2-M apart is its attention to detail. The upper is forged from T6 7075 aluminum and hard-coat anodized for durability, while the 15-inch PicLok free-float handguard gives you genuine flexibility: mount Picatinny rail or M-LOK accessories wherever you need them, without compromise. You get a flared magazine well for faster reloads, an integrated trigger guard, and a Radian Raptor ambidextrous charging handle that works from either side. The 3-setting adjustable gas system lets you dial in the balance between reliability and soft shooting, or run it unsuppressed in adverse conditions.
The 7.62x39 chambering is the real story here. It's effective for hunting medium game, economical to shoot at volume, and offers proven terminal performance. The 1:8 twist barrel is optimized for the full range of 7.62x39 ammunition, and the mid-length gas system keeps things smooth and manageable in a 16-inch platform.

Yes. The 7.62x39 cartridge is effective for hunting medium-sized game, and the 16-inch barrel provides practical velocity and handling for field work.
Yes. The PicLok handguard is free-floated, meaning it does not contact the barrel, which helps with accuracy consistency. It also allows you to mount both Picatinny rail and M-LOK accessories.
