Full description and what we offer
Primary Weapons Systems was founded in 2008 by firearm enthusiasts who noticed something obvious after testing rifles at high round counts: direct impingement systems required way more maintenance than piston-driven designs, especially in adverse conditions. That realization became the PWS long-stroke piston system—an AR platform that keeps the core AR-15 design intact while cutting maintenance demands dramatically.
PWS manufactures a full lineup of tactical and sporting rifles:
AR-15 / MK1 Series - Complete rifles and pistols - Uppers, lowers, and conversion kits - Barrel lengths from 7.75" to 16" - Calibers: .223 Wylde, 300 Blackout, 6mm ARC
AR-10 / MK2 Series - Full-size rifle platforms - .308 Win and other large-frame calibers
UXR Rifles - Limited release modern sporting rifles - Available in .223 Wylde and .308 Win - ELITE configurations with FRC Compensators
Suppressors & Muzzle Devices - 3D-printed suppressor technology - BDE (Backcountry Defensive Equipment) line - FRC (Fast Recoil Compensators) in multiple port configurations - Caliber-specific options: .22LR, .223/5.56, .308/7.62, .338/8.6
Every PWS component gets made on state-of-the-art CNC machines. Parts not produced in-house come from top manufacturers only. The company is staffed entirely by shooters—machinists, assemblers, QC, office staff—which means designs are built by people who actually use them.
PWS tests rifles through rapid fire, accuracy runs, water immersion, mud, and drop tests. They publish real performance data.
