A while back one of the guys here posted something to the effect that the best way of dealing with the hellish recoil of .223 was to stuff a maxi-pad under your bra strap. I thought it was hilarious.
I was looking at getting a comp while I had my 10.5" Norc on order, but after I got it and shot it some, I decided not to bother; it wasn't as loud as I had expected, and the recoil was non-existent, at least relative to the milsurps I usually shoot. I do like the looks of the Noveske Pig and the Dlask clone, though, and might get around to getting one of those eventually...
