What’s the most reliable .45 ACP upper that you can put on a standard lower? Most that I see are Olympic Arms trash or other off brand. Does a .45 upper that’s reliable and durable even exist?
Probably needs to be asked on the AR pistol an pistol caliber AR forum:

If it needs to be moved that’s fine. I wasn’t really sure whether I should put it there or not since I’m talking about a 16" rifle upper, but it is definitely a pistol caliber AR.
Best? How about cool?
