The Primary Weapons Systems MK116 MOD 2-M is a revamped upper receiver line introduced in 2018, incorporating the reliable PWS long stroke piston system for superior functionality and durability. It boasts patent-pending PicLok technology on the free float handguard, allowing seamless mounting of Picatinny or M-LOK accessories to customize your firearm setup. Crafted with fully forged upper and lower receivers, this model eliminates the forward assist for a sleeker design while adding a flared mag well and built-in trigger guard for improved ergonomics and ease of use. Designed for the 7.62x39 caliber, it includes a 16.1-inch barrel and Triad30 muzzle device, making it ideal for precision shooting and tactical applications. The anodized finish and black color provide excellent resistance to wear and environmental elements, ensuring long-lasting performance in various conditions. Compatible with AR-15 platforms, this upper receiver comes with a Radian Raptor charging handle and M-LOK handguard, offering a compact and ready-for-action build that appeals to both aesthetics and functionality.
