Description
 
These are the last of them we expect to arrive until possibly April 2021

We are thrilled to offer our own complete lustrously diamond polished Nickel Boron finished 6.5 Grendel bolt carrier groups made for us by a leading ISO 9001:2015 manufacturing and assembly certified company that specializes in bolt carrier groups.

These are the slickest 6.5 Grendel Bolt Carriers we offer and are perfect for maintaining reliable functioning during the more demanding conditions.

This BCG features a SAAMI specified bolt face (so-called "Type II") for widest commonality with quality manufactured barrels and is assembled with the vaunted o-ring for increased extraction reliability. Coated with a matte finish of nickel boron that has a low coefficient of friction, meaning the slicker surface will aid in reliability and easier clean-up, plus it looks great.

Made in the U.S.A

4 of 5 Not quite "diamond polished" March 27, 2021
Reviewer: Giovanni Tenorio from TEXAS!!!  
The BCG looks nice and stout with all right angles nice and sharp. No real, left-over machining marks and it looks like it'll take a good amount of use and abuse!! HOWEVER, according to the spec list, it claims to be "diamond polished" and the picture itself looks really slick. Unfortunately, mine came with a dull finish and doesn't feel slick, like normal nickel boron should.
