Exactly what I was looking for. Processed and shipped quickly. Thanks!
Perfect finish. Fit nicely in my upper. Threads are concentric to the bore and my suppressor threaded on snuggly and stays tight. 147gr standard factory loads stay subsonic at this length. Accurate. Will be buying a 16" for my father's 9mm build.
