Palmetto State Armory PA-15 LW-Series 5.56 NATO 16" Carbine with Free-Float Quad-Rail
This PA-15 combines a Palmetto State Armory LW-series forged lower with a less-common DPMS-marked 16-inch chrome-moly barrel and a free-float quad-rail handguard.

The DPMS 1:9-twist barrel gives this carbine a twist rate preferred by shooters who often run 55- to 62-grain ammunition, setting it apart from PSA’s more common 1:7 offerings. The barrel is button-rifled, chrome-moly steel, and finished in phosphate or nitride for durability.
A free-float quad-rail handguard with T/L/R numbering provides ample room for lights, lasers, and accessories while keeping the barrel isolated for better accuracy. The carbine-length gas system maintains reliable cycling across a wide range of loads.
The 7075-T6 forged receivers wear a hard-coat anodized finish, and the lower displays PSA’s crossed-cannons logo. A mil-spec six-position stock, Hogue-style grip, and pre-installed Magpul AFG deliver familiar ergonomics right out of the box.
A fixed A2 front sight base pairs with the flip-up rear BUIS for immediate use, and the flat-top receiver is ready for optics. The threaded 1/2x28 muzzle allows quick attachment of flash hiders, brakes, or suppressors.
The blue-anodized bolt head offers a unique visual cue while maintaining standard AR-15 compatibility. Overall, this modular build blends proven PSA components with a desirable DPMS barrel for shooters who want a reliable, accessorized 5.56 NATO carbine.
