Description
The Primary Weapons Systems MK111 MOD 2-M is a short barreled rifle chambered in .223 Wylde and built around PWS's long stroke piston system with a 3-setting adjustable gas regulator delivering the reliable cycling and reduced fouling of a piston-driven platform in a compact 11.85 barrel configuration. The 41V50 stainless steel button-rifled barrel provides exceptional accuracy and barrel longevity and the PWS FRC 2-port muzzle device manages recoil and muzzle rise effectively on the short-barreled platform. A PWS proprietary piston upper built from T6 7075 forged aluminum with an anodized finish combined with a fully forged lower featuring a flared mag well and built-in trigger guard reflects the precision craftsmanship that defines the MOD 2-M line. – The 11 M-LOK free-floated handguard incorporates PWS's patent-pending PicLok technology allowing users to mount both Picatinny and M-LOK accessories on the front section without separate rail segments delivering maximum accessory versatility in a slim free-floated profile. A Radian Raptor ambidextrous charging handle provides positive ergonomic manipulation from either side of the rifle and BCM adjustable stock and pistol grip deliver proven field-tested ergonomics for a wide range of shooter sizes and shooting positions. The elimination of the forward assist and the addition of a flared mag well and built-in trigger guard reflect deliberate design choices that streamline the platform and improve the shooting experience. – Primary Weapons Systems developed the MK111 MOD 2-M as the go-to SBR for shooters who want a single AR platform capable of handling hog hunts law enforcement and SWAT training courses and demanding recreational use with equal effectiveness. The .223 Wylde chamber accepts both .223 Remington and 5.56 NATO ammunition maximizing ammunition versatility without accuracy compromise and the long stroke piston system significantly reduces the maintenance demands compared to direct impingement alternatives in sustained or suppressed fire applications.
