A friend of mine got his first can, a Dead Air Mask. When he screwed it onto his Ruger bolt rifle, the rifle started spraying like 7 shot with no choke. I asked him about baffle strikes, but he can't see any evidence of any. His threads are also reportedly concentric. I've heard good things about Dead Air, but is it possible the QC was lacking on this can? I am posting bc I have never heard of accuracy loss with a 22 can.
