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

The Toolcraft AR10 / 6.5 Creedmoor Bolt Carrier Group, Double Ejector – DLC is a premium, U.S.-made component engineered for high-pressure AR-10 applications. Designed specifically for the 6.5 Creedmoor cartridge, this Toolcraft AR10 / 6.5 Creedmoor Bolt Carrier Group features a dual ejector system and reduced-diameter firing pin channel, supporting smooth cycling and consistent extraction. Built to DPMS pattern specifications, it is fully compatible with receivers chambered in 6.5 Creedmoor and other .470 bolt face calibers.

The Toolcraft AR10 / 6.5 Creedmoor Bolt Carrier Group, Double Ejector is constructed using a 9310 steel bolt and an 8620 steel carrier. The entire assembly is coated in Diamond-Like Carbon (DLC), a technologically advanced surface treatment known for its extreme hardness—rated at 90 Rockwell—and ultra-low friction characteristics. DLC is self-lubricating in dry conditions, highly resistant to wear and corrosion, and offers greater lubricity than Nickel Boron. Its easy-clean properties make it ideal for shooters looking for low-maintenance, high-performance parts.

The full-auto profile carrier includes forward assist serrations and a 4130 steel gas key, properly staked with Grade 8 fasteners for long-term durability. The bolt is MPI-inspected and shot peened for structural reliability, while the extractor is machined from 4140 steel and includes a mil-spec O-ring and triple gas ring configuration to improve case retention and ejection performance under high-stress firing cycles.

Included in the assembly are a cam pin crafted from 8620 steel, a 416 stainless steel firing pin, and dual ejectors—an upgrade that addresses known ejection issues in large-frame AR platforms. The reduced 0.065″ firing pin diameter matches the pin channel, enhancing compatibility and performance in dual ejector configurations. These design features collectively offer improved reliability for 6.5 Creedmoor and similar high-pressure cartridges.

All Toolcraft Bolt Carrier Groups sold by Arm or Ally are sourced directly from the manufacturer and include a 100% no-questions-asked lifetime warranty. Toolcraft does not honor DLC coating claims from units processed by third-party coating services. Purchasing through an authorized dealer ensures full product and finish coverage. Trusted by the U.S. military and commercial rifle makers, Toolcraft delivers one of the most proven AR-10 bolt carrier groups available today.
