I wanted an extra bolt assembly to keep in the grip compartment for a backup, and happened to see a review of this AB Arms bolt carrier group online. I liked the idea of it being slicker, so supposedly carbon gunk won't stick as easily. The vet-run company has a good reputation, and builds these items to a high standard in materials and workmanship. So instead of getting individual parts, I got this BCG as an upgrade and took the bolt, firing pin, and pins from my original BCG and put them in the grip for backup. I was a little concerned about headspace, so I ordered a Max Nato field headspace gauge to check it. Headspace was fine. I've used the AB Arms BCG for a few hundred rounds and it's worked fine. Since it's silver colored, I can now see buildups of carbon that would have been hidden with my previous black colored BCG.
