Your 7.62X39 AR build deserves the best bolt carrier group money can buy. This 7.62X39 BCG by Toolcraft is the highest quality BCG on the market today. Finished in Black Nitride for a lifetime of flawless performance. Toolcraft products are also trusted by the U.S. Military and carry a lifetime warranty.

At SpiceTac, we buy these BCGs direct from Toolcraft in bulk before any logos are applied. This allows you to get one of the best AR15 bolt carrier groups on the market but without a logo and without the steep markup. A Toolcraft BCG really is one of the best kept secrets in the world of the Black Rifle! Speaking of secrets...


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!
