Last fall I got an A2 profile 22LR barrel from CMMG. I mated it with a bolt kit from them I had purchased previously.
So I built it up this summer.
It functioned perfectly, but there was a bore defect that was affecting accuracy.
I explained the issue and they said to return it. Even sent a call tag.
Finally got around to mounting the replacement barrel this weekend. Function was perfect, and the accuracy was excellent with Federal Automatch.
Around 1" at 50 yards before my eyes fuzzed out. This will be my Appleseed gun next spring.
