Toolcraft knows bolt carrier groups. It’s what they do, and they do it well. A Toolcraft BCG is built to the highest standards out of the highest quality materials and must pass a long list of requirements before they are shipped out the door to ensure you get a product that will last a lifetime. With a variety of calibers and coatings to choose from, you can find the right one for your build. This Toolcraft BCG is built for 5.56 NATO AR-15 rifles with an M16 profile and rated for full auto use. To ensure it can withstand the wear and tear of heavy use, the carrier is machined from 8620 aircraft quality steel which features a lower carbon content and is case hardened for high strength durability. More importantly, the bolt itself is made from Carpenter 158 tool steel and shot peened to improve high pressure performance. The entire Toolcraft BCG is finished with a Salt Bath Nitride process which physically changes the surface of the material which makes it easy to clean and smooth to run. Toolcraft Inc. is the name you should be searching for when building out your new AR-15.
