I have a dead air mask 22 and the banish 22. Both are nice, I’m not convinced that it makes much difference on a bolt action rifle compared to a pistol and the banish 22 is lighter than the mask but apparently the mask is one of the best out there. Eventually I’ll order a thunderbeast takedown 22 but it’s not a priority at this point.
I honestly don’t know which one I like better, the banish 22 has worked well for the year I’ve had it and I have no complaints about it. I got the mask out of curiosity and I can’t tell a difference sound wise. Rimfire suppressor technology seems to be pretty good these days. If you care about first round pop or shoot a pistol a lot it would make more of a difference. For me, only shooting bolt action rifles with sub sonic ammo, I honestly can’t say that I’d notice a difference between my mask and the banish if I didn’t see which one I was using.
