I guess I’m in the cool guy club now. Never had any issues with either of my zev oz9c until this happened on the last stage of our local match. Gun has been fed a steady diet of 147 black bullets over titegroup at 950fps. I had planned on shooting open that day a switched to carry optics the night before because I was having some feeding issues in my open gun that I am blaming on some old weak mag springs. Got to the match and had my open ammo in my bag instead of the carry optics minor ammo and ended up borrowing some Winchester white box 115 from a buddy and last stage of the day the lug sheared off and locked the gun up pretty good. I emailed zev some pictures and they sent me a new barrel. Ran 500 rounds through it yesterday with no malfunctions and it still had the same point on impact so I’m happy about that. Hopefully this barrel doesn’t cause any other issues.
