Made in the U.S.A – Lifetime Warranty

The Toolcraft AR10 308 Bolt Carrier Group in black nitride is manufactured using a 9310 steel bolt and an 8620 steel carrier. Compatible with most calibers in the 308 parent cartridge family. If building a 6.5 Creedmoor, we recommend the Toolcraft 6.5 Creedmoor Bolt Carrier Group as it is 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 proudly feature Toolcraft products and our fantastic line-up of reputable manufacturers.

We also offer a Toolcraft 308 Double Ejector BCG for ultimate reliability. The 308 dual ejector BCG features a 0.065″ reduced diameter firing pin and firing pin channel. Historically, the large format AR10 variants are known to have ejection problems. The addition of the second ejector ensures consistent ejection and greatly improves the reliability of your AR10 rifle.
