Worth the extra money - American Built Arms Company PRO 5.56 Bolt Carrier Group (BCG)

I just returned a boron-nickle coated BCG from another company, which I had bought from another online retailer -- it turned into a nightmare, and this was a fairly well known sight. Word of caution: look to be sure that retailer even HAS a return policy, as this one had a policy of NO returns! I ended up replacing that one with a BCG from American Built Arms. Planet Optics gave me a good price, and I am 100% satisfied. The BCG is well-finished, no mistakes in machining, and it slides up and down inside the upper as smooth as glass, and the company supports American workers. I was so impressed with that experience that today I bought an additional American Built Arms bolt from Planet Optics, as well as an Aimpoint Pro Patrol optic. Now I know where to shop!
