I picked up one of their older 10/22 retrofit barrels a while back pre the change to the barrel bolt system. I had it sitting around for a while before I got it installed. I found that it was rupturing every case I shot through it. I contacted them to see what the issue might be since I was using good ammo. I sent pictures of everything. I never heard back from them. I had planned to grab one of their La Chassis for my 457, but after this I can't in good faith deal with them. I went with an MDT chassis and haven't looked back.
