I 100% use hear pro with all suppressed shooting, even 22 subs. I have tinnitus even though I have always used plugs and muffs and always worn plugs when doing anything loud (going on factory floor, mowing the lawn, doing carpentry etc.). I have only fired a handful of shots without hear pro, mainly when hunting. I had hearing testing done and my hearing is actually really good, but the tinnitus is pretty loud and annoying...dr said it was due to stress which is a definite possibility especially now that I'm technically a supervisor at work and given my GF's chronic health problems, but I still don't want it to be any worse if it is from exposure to loud sounds.
I'm going to be back full-time in NC in about two weeks (yaaaay!). I want a new dedicated 556 short suppressor for my 12.5" SBR. This is mainly for concussion and flash reduction. I'm going to be carrying this a lot through mountains, so I want something pretty durable, light and short, that isn't outrageously expensive, but like I said gets good flash reduction and some concussion and sound reduction. I was thinking a griffin Recce-K in 556 since I already have a bunch of griffin muzzle devices. Any opinions on that or another can?
