The Primary Weapons Systems PWS MK110 Alpha SBR 5.56 10.5 ODG is a premium long-stroke piston-driven AR platform built for shooters who want refined recoil control and dependable performance. Its 10.5-inch 416 stainless steel nitride-coated barrel is chambered in 5.56x45mm NATO with a 1:7 twist and capped with the FRC 2-port compensator, delivering excellent flash and recoil mitigation while remaining suppressor-ready. The steel plate-reinforced Alpha M-LOK handguard, green anodized receivers, and ambidextrous Radian controls create a modern, duty-grade rifle with intuitive handling from either shoulder.

This MK110 Alpha is optimized for suppressed use thanks to a forward-accessible, three-position gas adjustment knob that keeps the action cleaner and running cooler over extended strings of fire. The A5 buffer system and Sprinco spring smooth out the recoil impulse, while the Geissele Super Dynamic Enhanced trigger supports precise, repeatable shots. Outfitted with Magpul MOE SL-S stock, K2 grip, and a 30-round PMAG, this rifle is well suited for range work, training, and general-purpose defensive roles. Primary Weapons Systems’ attention to detail and piston system innovation are evident throughout this compact, feature-rich carbine.
