While M-LOK has been widely accepted, the PWS engineering team sought a way to retain picatinny compatibility on the handguard along its cardinal sides. This desire led to the conception of the ‘PicLok’ system that is featured on PWS MK1 and MK2 MOD 2 rifles and uppers. This hybrid combination is the best of both worlds, merging M-LOK and Picatinny technology into one versatile rail design.

The FRC compensator by PWS is not just another muzzle device—it's engineered for shooters who demand high performance and suppressor compatibility. Available in both 2-port and 3-port versions, the FRC reduces recoil and makes your firearm more controllable without sacrificing precision.

If you’ve ever built an AR-15 or AR-10 from tip to tail, you’re probably familiar with Milspec buffer tubes, castle nuts and endplates. These parts haven’t changed much since the 1950’s, but the engineers at PWS saw room to improve upon the classic design. Meet the PWS Enhanced Buffer Tube and Ratchet Lock Castle Nut and Endplate!

Primary Weapons Systems is proud to announce its sponsorship of the Rescue 22 Foundation Shooting Team. PWS will be the team’s exclusive rifle sponsor, providing team members with PWS piston-driven rifles to shoot in competitions.
