7.62 x39 bcg

Your 7.62×39 AR (7.62 x39 bcg) build deserves the best bolt carrier group money can buy. This 7.62×39 Nickel Boron BCG by Toolcraft is the highest quality BCG on the market today. Finished in Nickel Boron for a lifetime of flawless performance. Toolcraft products also trusted by the U.S. Military and carry a lifetime warranty.

Nickel Boron is an extremely durable finish with self-lubricating properties so your AR15 cycles smoother and requires less lubrication. Toolcraft has the Nickel Boron finish applied by UCT Coatings of Palm City FL, the same company that applies it for Fail Zero BCGs. Called EXO Technology, this is a patented process that applies a Nickel Boron finish so durable that it is specified on Army 81mm and 60mm mortar tubes, Blackhawk helicopter hoists, and for hard use applications on some Navy ships!  IMO, this may be the ultimate upgrade to the All-American AR-15. And it looks good too!

The AR-STONER™ 7.62x39mm Bolt Carrier Group is a great option for your next AR build. Chambered in the popular 7.62x39mm Caliber, this BCG machined to strict military standards. State of the art magnetic particle testing ensures the assembly is free of imperfections and will function flawlessly.


Note: Some dealers selling Toolcraft BCGs that have finished after leaving Toolcraft. The finish on those BCGs would not be warrantied by Toolcraft. All Toolcraft bolt carrier groups sold by SpiceTac include the 100% no-questions-asked Toolcraft warranty.
