Description

Free Shipping on all Toolcraft Bolt Carrier Groups!

Toolcraft Inc. is an OEM manufacturer of bolt carrier groups (BCGs) for many firearms 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.

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!

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!

Reviews: With over 150 5-Star Reviews the Toolcraft Black Nitride BCG is one of our best reviewed products! Again and again, shooters just like you have become believers in the quality and value of Toolcraft products. You can see our own review here: Toolcraft BCG Review - Best Black Rifle Secret Ever?
