This seems to be a nice enough barrel, although I have yet to shoot it. Just wanted to point out that it is not 7.5" long, it is actually 9" long.
7.5 .22 barrel

Bought a 7.5 ..22 upper from PSA tried to zero and got 10-12" groups never the same place twice ordered 7.5 barrel from Grid Defense installed and getting 1/2" groups at 25 yds understand these are produced by CMMG definitely would recommend!
