Hey guys. I am buying a used AR barrel and have a question. The owner doesn't know how many rounds have been shot through it but says it still shoots a decent group. I don't need a tack driver just a good barrel for a retro build. What should I look for? Anything I can test with basic tools (Micrometer, dummy round, etc)?
Thanks for the answers. |
