The Toolcraft AR10 Nickel Boron Bolt Carrier Group is manufactured using a 9310 steel bolt and an 8620 steel carrier. DPMS Compatible with most calibers in the 308 parent cartridge family. If building a 6.5 Creedmoor,  we also offer a Toolcraft 6.5 Creedmoor Nickel Boron Bolt Carrier Group which is 100% compatible with the high-pressure 6.5 Creedmoor Cartridge.

Toolcraft is an OEM for the U.S. military and many other large rifle manufacturers, producing the most popular, and well built AR10 bolt carrier group on the market. Forget the fancy logo at a $75 premium, and buy directly from Arm or Ally, the internet’s largest dealer of Toolcraft products. All of our Toolcraft Bolt Carrier Groups come with a 100% hassle free Lifetime Warranty – should any Toolcraft product fail, contact us for replacement. We are proud to feature Toolcraft products along with our already fantastic line-up of reputable manufacturers.

We also offer a Toolcraft 308 Double Ejector BCG for the ultimate in reliability. The 308 dual ejector BCG features a 0.065″ reduced diameter firing pin, and firing pin channel.
