We’ve gone and done it!! The best damn BCG’s on the market are now being offered direct from

Blackwood Arms. For years we’ve been supplying a number of manufacturers with Mil-Spec Bolt Carrier

Groups, so we thought it would be a great time to offer them to all of our customers.

This is the same BCG that you will find in some of the BIG NAME manufacturers OEM guns. When a

client came calling on us and saw the crates of BCG’s being prepped for shipping they immediately

demanded to purchase a few. We realized that we shouldn’t keep something so damn sexy tied up for

just OEM work, and at that point we knew that something so good couldn’t be kept a secret forever.

Just like all BWA parts, good looks are just part of the promise, these carriers will provide you with

function and longevity that you can count on.

Bolt Carrier Group fits AR15/M4 compatible style Rifles (i.e.) .223/5.56mm, .300 Blackout.
