Run Your 6.5 Grendel or 6mm ARC Upper Right with a NiB BCG

It’s important to have a bolt carrier group that has everything you need. MPI inspected bolt, properly staked grade 8 gas key screws, chrome plated firing pin, plus a lifetime warranty, just in case. There’s plenty of tough finishes out there too, but few are as slick and tough as Nickel Boron.

Nickel Boron (NiB) coated bolt carriers have greater lubricity than your standard phosphate finish, and are easier to clean than black nitride. At the very least, it’s easier to see how much carbon you can wipe off to reveal the chrome-like finish after a day of shooting. And it’s a perfect match for a 6.5 Grendel Type II barrel, or the new 6mm ARC.

The BCG is the workhorse of your rifle – and it pays to have one that runs reliably. And it’s easy to keep this one in tip-top condition for a lifetime of use.
