The 7.5-inch barrel is machined from 4150 CMV steel, treated with a nitride finish for corrosion resistance, and threaded 5/8-24 to accept brakes or suppressors; an A2-pattern flash hider is installed.
A forged 7075-T6 upper receiver with “A” forging mark sits atop a matching hard-coat anodized lower marked “PA-15 MULTI.” The pistol-length direct-impingement gas system and free-float 6-inch aluminum M-Lok handguard keep weight to roughly 5.5 lb while preserving accuracy.
PSA’s single-stage Enhanced Polished Trigger breaks at approximately 5 lb, giving a clean, predictable pull. An ambidextrous SB Tactical SBA3 brace provides five-position length adjustment and a Velcro strap for added stability.
The platform accepts standard STANAG magazines; four 20-round PMAG GEN M3s ship with the pistol, offering a 20+1 capacity in .300 AAC Blackout. Flat-top Picatinny rails on the upper and handguard make optic and accessory mounting straightforward.
