A compact, mission-ready piston AR built for operators, instructors, and serious range shooters, the PWS MK1 MOD 2-M blends low-maintenance reliability with precision. The long-stroke PWS piston system and 3-setting adjustable gas let armorers and end users tune the rifle for suppressed use or specific loads, while Boise-made barrels and a Sub-MOA accuracy guarantee make it equally at home on precision workups. PicLok™ handguard flexibility, ambidextrous controls, and suppressor-optimized features deliver a short, durable package that stays paperwork-simple with a pinned muzzle device.
