Toolcraft 224 Valkyrie Bolt Carrier Group – Black Nitride

The Toolcraft 224 Valkyrie Bolt Carrier Group – Black Nitride is a robust, M16 full-auto profile BCG engineered for AR-15 rifles chambered in 224 Valkyrie. Manufactured in the U.S.A. with precision machining and premium materials, this assembly is coated in Black Nitride to enhance surface hardness, lubricity, and corrosion resistance, ensuring long-lasting performance during extended shooting sessions.

Constructed with a 9310 steel bolt and an 8620 steel carrier, both components are shot peened and MPI-inspected to verify structural integrity. The Black Nitride finish forms a durable bond that resists wear and reduces friction compared to standard phosphate coatings, making it easier to clean and maintain under sustained firing conditions.

The bolt features a machined D2 tool steel extractor with a Mil‑Spec O‑ring and triple gas rings to ensure reliable case retention and consistent ejection. Additional precision components include a 416 stainless steel firing pin and an 8620 steel cam pin, all assembled to Mil‑Spec tolerances for dependable operation in high-pressure 224 Valkyrie environments.

The Toolcraft 224 Valkyrie Bolt Carrier Group full-auto profile provides added mass, promoting smoother cycling and enhanced reliability—especially valuable in suppressed or rapid-fire scenarios. Built with the same quality standards used for military applications, this carrier group is ideal for competition shooters, precision rifle enthusiasts, and hunters targeting extended-range performance.

All Toolcraft BCGs sold by Arm or Ally are factory-coated and assembled by Toolcraft in North Carolina, preserving the lifetime warranty. Units re-coated by third-party vendors may void coverage. For shooters building or upgrading a 224 Valkyrie AR, this Black Nitride BCG offers a dependable, clean-running solution backed by Toolcraft’s uncompromising quality.
