What’s Included
- Palmetto State Armory PA-15 Nitride M4 Carbine Free-Float M-LOK rifle
- One 30-round Magpul PMAG polymer magazine
The 16-inch barrel is machined from 4150 CMV steel and QPQ nitride treated inside and out, adding corrosion resistance and a slick, easy-to-clean finish. Its M4 profile keeps weight manageable without sacrificing durability.
A 13.5-inch free-float aluminum M-LOK handguard removes pressure from the barrel, which can help maintain accuracy during rapid strings of fire. Ample M-LOK slots allow easy attachment of lights, grips, or bipods without excess bulk.
Forged 7075-T6 upper and lower receivers wear a hard-coat anodized black finish for wear resistance. The lower is marked "MULTI," letting owners convert to other calibers with a simple upper swap.
The carbine-length direct-impingement gas system is paired with a six-position collapsible stock and A2-style polymer pistol grip, offering adaptable ergonomics for shooters of different sizes or gear setups.
A standard two-position safety selector, threaded muzzle (1/2x28 TPI), and 30-round PMAG round out a straightforward, mission-ready configuration, all made in the USA. A DCSF serial prefix places this rifle in PSA’s 2020-era forging batch.
