Product Overview — Compact Power, Practical Design

The TacFire SSPK300LPK10 AR Build Kit Pistol is engineered to give builders a compact, reliable foundation for a .300 Blackout AR pistol. The kit pairs pistol-length geometry with durable parkerized steel components to withstand the increased cyclic stresses and heat of short-barrel use. Its 5/8"-24 tpi muzzle threading supports a wide range of muzzle devices and suppressor interfaces, while the pistol-specific form factor keeps overall length and weight down for easy handling in tight spaces.

Key Features & Benefits

• Chambered for .300 Blackout: Designed specifically for the .300 AAC Blackout cartridge (300 BLK), delivering subsonic and supersonic flexibility on a short-barrel platform.

• Pistol Platform Geometry: Optimized component lengths and clearances for AR pistol builds—great for compact defensive builds, short-range hunting, or versatile range rigs.

• Black Parkerized Steel Construction: Durable parkerized finish on steel components improves corrosion resistance and provides a low-glare tactical appearance that stands up to heavy use.

• Standard Muzzle Thread (5/8"-24 tpi): Common muzzle threading for .300 BLK pistols, giving wide compatibility with flash hiders, muzzle brakes, and suppressor adapters.

• Sports South Exclusive Package: Exclusive kit configuration (SSPK300LPK10) only available through Sports South — useful for builders seeking a distinct parts bundle or limited-release SKU.

• Precision Fit & Durability: Machined and finished to industry tolerances to ensure coherent function with compatible AR pistol lowers, buffers, and accessory components.
