PSA PA-15 16" Mid-Length 5.56 NATO – Lightweight M-LOK Classic Free-Float Edition
The Palmetto State Armory PA-15 featured here is a factory-built, full-size AR-15 that blends mil-spec reliability with modern weight savings. Anchored by a 16-inch, 4150 CMV steel nitride barrel and a 15-inch free-floating Lightweight M-LOK handguard, it delivers solid accuracy, softer mid-length gas impulse, and ample real estate for accessories—all while keeping forward ounces to a minimum. Forged 7075-T6 receivers, a Carpenter-158 bolt, and a government-profile barrel mirror military standards, yet the rifle stays light, sleek, and ready for customization.
Condition
Excellent overall. Outside surfaces show only faint handling marks, and controls remain crisp. The bore is spotless with a mirror finish; lands and grooves are sharp, indicating very limited round count and proper maintenance from day one.
What’s Included
• One Magpul PMAG 30 GEN M3 30-round magazine.
The heart of this PA-15 is its 16-inch 1:7-twist nitride-finished barrel, optimized for the full spectrum of 5.56 NATO loads and terminated in a 1/2-28 threaded muzzle with the classic A2 flash hider. The mid-length gas system reduces recoil impulse and component wear compared with carbine-length setups, making follow-up shots smoother and sight recovery quicker. The 15-inch Lightweight M-LOK rail deletes most of the 12-o’clock Picatinny while retaining critical slots up front, giving you a rigid, free-float platform that sheds forward weight without sacrificing accessory flexibility.
Controls stay familiar: a standard left-side SAFE/FIRE selector, mil-spec single-stage trigger, and standard bolt catch and mag release. The six-position M4 stock provides a 10.5-inch length of pull at its shortest, fitting a wide range of shooters, while the A2-style grip offers a secure, no-nonsense hold. Because the lower is marked “MULTI,” you can pair it with any caliber-appropriate upper without new serialization, adding versatility for future builds.
Made entirely in the USA, this PA-15 is an accessible, turn-key path into the AR platform or an excellent foundation for a tailored rifle project. Its combination of forged strength, proven materials, and smart weight reduction makes it equally comfortable as a training workhorse or a lightweight defensive carbine.
