tc,
ProEars dimension 1 Stalker model. I use them and see lots of folks using them every weekend in IPSC matches. They seem to be the choice, as well, for the three gun shooters that wear electronic muffs. The sporting clays model has the same ear cups. I have never had mine interfere with the comb on a shotgun or my AR under any shooting conditions, whether that be trap/skeet/sporting clays, IPSC, hunting, or benchrest. YMMV
