Not Brownells fault, barrel issues

First issue.headspace issues are still common with their barrels unless you get the head spaced bcg that is matched for the barrel that you have actually bought. I couldnt get my brand new bcg to pass with the go gauge. So, before you buy this barrel you should consider buying it straight from them with a matched bcg, or be ready to check for proper headspace and additional work to make it work if needed. Second issue.dent/nick on the barrels extension lip that should have been caught by someone before being shipped off to brownells, so pretty much that upward dent would be rubbing on the inside of the upper while being installed, and you would have to beat that thing with a hammer to install it all the way into the upper. Waiting to hear back from barrels manufacturer to make this right. If not Im sure Brownells will take care of me as always
