Description

Free Shipping on all Toolcraft Bolt Carrier Groups! 

Toolcraft Inc. is an OEM manufacturer of bolt carrier groups (BCGs) for many AR15 makers. These companies know they can trust Toolcraft quality and are proud to have their logos applied to Toolcraft BCGs. Toolcraft products are also trusted by the U.S. Military and carry a lifetime warranty.

Finish is Black Nitride which is a metal treatment that produces a case-hardened surface. The resulting finish is extremely wear and corrosion resistant. It is also very slick, especially compared to the traditional phosphate finish. This means that all contact surfaces of the BCG will experience less friction and smoother, more reliable function. Easy clean-up of this smooth surface is a nice bonus. The rich black color on these BCGs looks great on the Black Rifle!
