For firearm enthusiasts seeking a reliable and versatile rifle that combines classic design with modern features, the Palmetto State Armory PA-15 Classic AR-15 Rifle stands out as an exceptional option. Chambered in the widely used 5.56 NATO caliber, this rifle offers a blend of quality construction, thoughtful engineering, and user-friendly components, all housed in a tough and lightweight package. Whether you're a seasoned shooter or registering your first AR-15, this rifle delivers performance and value without compromise.

Robust Barrel Construction and Precision Engineering

At the heart of the PA-15 Classic is its 16-inch chrome-moly vanadium steel barrel. Known for its durability and corrosion resistance, the chrome-moly vanadium steel barrel ensures consistent accuracy even under demanding conditions. It features a 1:7 twist rate, stabilizing a wide spectrum of bullet weights—from lighter 55-grain rounds to heavier 77-grain projectiles—enhancing versatility for target practice, hunting, or tactical use.

The M4 profile barrel includes a carbine-length gas system, a military-proven design balancing recoil management and reliability. Topped with a low-profile gas block and a classic A2 flash hider, this setup delivers smooth operation and mitigates muzzle flash for better shooting comfort in low-light scenarios.

Innovative Free-Float Handguard with Hex M-LOK Design

A standout feature of the PA-15 Classic is its 13.5-inch Hex full Picatinny M-LOK free-float rail, crafted by PSA. This lightweight, hexagonal-patterned handguard is designed around the M-LOK system, allowing shooters to easily attach compatible accessories like foregrips, lights, lasers, and bipods. The free-float design means the barrel is free from external pressures, improving accuracy potential compared to traditional handguards that contact the barrel.

The hex pattern contributes both to aesthetics and weight reduction while maintaining structural integrity, striking a balance crucial for extended shooting sessions or tactical carries. The extended rail length offers ample space for accessory placement without crowding.

Machine-Made Upper and Lower Receivers for Durability and Reliability

The upper receiver is forged from 7075-T6 aluminum, well-known for its high strength-to-weight ratio, and machined to MIL-SPEC standards to ensure proper fit and function with a wide variety of AR-15 parts and accessories. The anodized hard-coat finish resists wear and corrosion, extending the rifle’s lifespan. Military-style features such as a forward assist and dust cover enhance reliability under adverse conditions.

The lower receiver maintains this high standard, also forged from 7075-T6 aluminum and marked "MULTI" to indicate compatibility with multiple calibers. This hard-coat anodized lower sports the PSA Classic Carbine Flat Dark Earth (FDE) stock and matching Classic FDE A2 grip, offering durability and ergonomic comfort. With six positions for buffer tube adjustment, users can tailor their cheek weld and length of pull for customizable comfort.

Reliable Bolt Carrier Group and Fire Control Components

The bolt carrier group (BCG) features a full-auto profile crafted from nitride-coated 8620 steel, ensuring smooth cycling and excellent resistance to corrosion and wear. It includes a mil-spec Carpenter 158 steel bolt that has been shot-peened for added durability. The gas key is hardened to USGI specifications, fastened with grade 8 screws, and staked per mil-spec standards, ensuring consistent gas flow and enhanced reliability.

The standard Mil-Spec AR-15 fire control group integrated into the PA-15 Classic guarantees crisp and consistent trigger pulls, suitable for precise shot placement whether at the range or in the field.
