Search didn't return anything recent on this:
Yesterday I was running my LPVO equipped AR and couldn't get a cheek weld without moving my right muff out of place. I'm using MSA Sordin's that I've had for about 10 years. Nothing I've tried comes close and they're fairly low profile too. Now, last night I ordered some gel cups for them... I didn't even know those existed until looking for threads on ear pro.
For rifle bare minimum, in addition to the gel cups, I'm going to double up with plugs and muffs. I have some OK plugs I custom molded at home.
So what are you guys/gals using? Suggestions?
