Ben from AR15news alerted me to these AIM BCG's as I've been looking for a nitride coated Bolt Carrier Group to run in my gun. I've wanted to try the nitride coated carriers, ever since another manufacturer was trying to perfect the nitride coating, but had a lot of issues with the product and customer service. Checkout AIM Surplus to order and get more information.

I'll try to post a review down the road once I get it going on a gun.
