Just my lil bit of experience with the mags from atlas. I shot a2 with a guy who had a brand new chaos. Got it Two or three days before match with all atlas tuned mags.
got to chrono and his 170 failed gauge. Something I think he should have checked before a major, but also something atlas should have not dropped the ball on.
I don’t know what the final verdict was on the guys situation, but at a2 they basically told him he is sol.
hopefully they got it figured out and took care of him
