BCG is very smooth and machined very well have not fired it yet but I'm sure it will work flawlessly I've never had any issues with the AR builds I've done.
usually purchase PSA bolts but ACME was running a sale on these so I decided to give it a try. Bolt runs great onot ran about 150 rounds thru it, hardly any marks on the coating just where the hammer rubs on it. will buy some more again.
Upon arrival and inspection of these bcg's I found no tool marks whatsoever. They function just as they should and the coating looks just fantastic. Please run these on sale again soon Acme machine.
Buy one now!
Rocks out in my 20” PSA Upper!
Great product, best price around
Great service great quality fast shipping
The great BCG . Great Bolt Carrier Group for a good price
Very nice I haven't had a chance to use these yet, but they looked great and arrived extremely fast. Keep up the good work Acme.
Sloppy machining This is a good looking bcg but when I ran it in my rifle it failex to seat and it was rough to pull back. I ended up having to mortar the rifle to pull the bolt back. Upon further inspection I noticed some marring on the gas tube from where it met up with the gas key. I removed the bolt and inspected the gas key to find that it wasn't cleanly machined and it had a sharp edge that got hung up on the gas tube. Eventually, after working the bolt, it removed material from the gas tube and restored normal function to the rifle. This bcc will have to stay with this rifle since I don't believe it'll easily swap to another without giving me malfunctions.
