Description

 

The Toolcraft 5.56×45 NATO/.223 Rem (or .300 Blackout) Bolt Carrier Group comes in the Nickel Boron finish to reduce overall wear and friction, and for upgrading your existing AR build. These Full Auto M16 Profile Direct Impingement BCG designs have multiple features that separate them from the average AR Bolt Carrier Group. They are Magnetic Particle Inspected for Quality Control, and built to Mil-Spec standards throughout. They have Mil-Spec 8740 Steel hard chromed Firing Pins, Mil-Spec Gas Keys with Grade-8 screws that are staked and sealed with Permatex No.3, and they have shot-peened case-hardened D2 tool steel extractors. These Toolcraft Inc. BCGs come from the factory with a Lifetime Replacement Warranty on the entire BCG.

NOTE- The Nickel Boron coating is well known for reducing friction because of its molecular structure, it offers great heat dissipation properties, reduces wear on the BCG and the corresponding parts, and it increases the longevity of the BCG. Nickel Boron coatings are also known to reduce problems with function due to the decrease in overall friction and wear.
