have a brand new Colt AR 15 match target competition with a 20" 1in9 twist barrel, what is the right procedure to break in the barrel ?
I have had a similar Colt for a couple of decades now...faster twist barrel. What I did was:
the right procedure...
1. shoot the gun
2. take it home
3. take back out some other time
4. shoot it some more.
5. repeat with cleanings every once in a while.
