Toolcraft AR10 / 6.5 Creedmoor Bolt Carrier Group, Double Ejector – Black Nitride

The Toolcraft AR10 / 6.5 Creedmoor Bolt Carrier Group, Double Ejector – Black Nitride is a high-quality BCG engineered for AR-10 rifles chambered in 6.5 Creedmoor and other .470 bolt face calibers. Made in the U.S.A. and backed by a lifetime warranty, this bolt carrier group delivers consistent performance and enhanced reliability, making it a trusted choice for both builders and serious shooters.

Constructed from a 9310 steel bolt and 8620 steel carrier, this BCG features a durable Black Nitride finish that enhances corrosion resistance, reduces friction, and supports long-term durability. The carrier includes forward assist serrations and a 4130 steel gas key, properly staked with Grade 8 screws to ensure secure alignment and function under stress. It is fully compatible with DPMS-pattern AR-10 platforms.

The bolt assembly incorporates a double ejector system and a 0.065″ reduced diameter firing pin and channel, designed to resolve common ejection issues found in large-frame ARs. This configuration promotes smooth cycling, flat loading, and consistent ejection in high-pressure calibers such as 6.5 Creedmoor, .308 Winchester, and .260 Remington. Each bolt is MPI-inspected and shot peened to ensure structural integrity and performance reliability.

Supporting components include a 4140 steel cam pin, 8740 stainless steel firing pin, a machined extractor with a Mil-Spec O-ring, and triple gas rings. These parts are selected for durability and compatibility with high-stress operation, ensuring the bolt carrier group performs consistently in demanding shooting conditions.
