I'm an experienced SASS shooter, but I'm looking for an opportunity to play with some other guns that I've got. What I'm curious about is the rifle element of 3-gun. It seems that most people I see in pics and vids are using either black guns, or the occasional AK. I don't have either one of those, and was contemplating using an M1 Carbine. There are 30-rd mags available for it, and it's light and handy. Is there any reason that such a critter wouldn't work?
