What’s Included
- PSA PA-15 M-LOK SBA3 5.56 NATO pistol
- Two 30-round Magpul PMAG polymer magazines
The 10.5 inch barrel is cut from 4150 CMV steel, nitrided for corrosion resistance, and capped with an A2 flash suppressor on a 1/2-28 threaded muzzle—ready for additional devices.
Around the barrel, PSA fits a roughly nine-inch free-float aluminum handguard featuring full-length M-LOK slots and short 1913 rail sections, giving plenty of space for lights, grips, and other accessories without adding bulk.
The upper and lower receivers are forged from 7075-T6 aluminum and finished with MIL-A-8625 Type III hard-coat anodizing in matte black. The flat-top A3 upper includes a forward assist, shell deflector, and ejection-port cover.
Stability comes from the SB Tactical SBA3 brace, adjustable through five positions and paired with a Magpul MOE pistol grip for a secure, ergonomic hold. A manual safety and STANAG-pattern magazine well round out the familiar AR-15 controls.
Built in PSA’s Columbia, South Carolina facility (serial prefix SCB), this pistol delivers mainstream AR-15 compatibility and dependable performance in a compact, range-ready format.
