The At3 bolt seems to be a quality part. Finish was nice and I had no problems with fit or function. Brass pooled in a neat pile from a bench rest.
Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
The bolt arrived very quickly and looks nice and clean. The only problem is that it fits very snug on the carriers I've installed it on. I'll probably have to polish it a little to loosen it up because it is not cycling properly. It extracts and ejects the casing correctly but does not chamber the next round.
