I’ve been very unhappy with my new CMMG barrel I bought for my dedicated AR .22LR build. I sent it back a couple of months ago and by the looks of it it could be a few more weeks or months before I get a replacement. I’m now thinking of getting a new custom barrel made so I can get operational again. The fact that their steel lined aluminum barrels is a plus as I want a featherweigh. What’s your experience with them?
