Features:

• 10.5" Barrel: The 4150 steel medium-profile barrel is nitride-coated for durability, corrosion resistance, and enhanced heat dissipation. Chambered in 300 Blackout, the barrel is optimized for both subsonic and supersonic rounds. With a 1:7 RH twist, it stabilizes the heavier projectiles common to 300 BLK. The barrel features M4 feedramps, ensuring reliable feeding and smooth cycling. Finished off with an A2 flash hider and crush washer, the barrel reduces muzzle flash for low-light shooting environments.

• M4 Flat Top Upper Receiver: Crafted from certified 7075-T6 aluminum forgings, this A3 flat top upper receiver is black hardcoat anodized to military specifications for strength and durability. The forward assist and dust cover are pre-installed for added reliability and ease of operation. The M4 feedramps contribute to flawless cycling during rapid-fire shooting.

• Precision Gas System: The .750 low-profile gas block is made from steel and black hardcoat anodized for excellent wear resistance. The pistol-length gas system ensures smooth cycling and function, specifically optimized for the 300 Blackout cartridge.

• Slim MLOK Handguard: The 10" MLOK slim-profile rail is crafted from aircraft-grade aluminum, ensuring a lightweight, rigid, and durable build. Finished in OD Green Cerakote, it not only provides a sleek look but also enhances the handguard’s resistance to wear and tear. The MLOK system offers versatile options for attaching accessories such as grips, lights, and slings.

• Versatile & Tactical: The OD Green Cerakote finish gives your build a rugged, tactical appearance, making it an excellent choice for those looking to stand out in both style and performance. The 10.5" length is ideal for those seeking a compact AR-15 pistol that can be maneuvered with ease.
