Dubbletrubble,
You certainly could, but isn't that the beauty of the whole thing? My safe has sidelocks, black rifles, elephant guns, revolvers, 1911's and all sorts of shotguns. They all do somethings well and other things not so well. The AR's are accurate, easy to shoot, and good for every critter from prarie dogs to coyotes. My M1A is a match grade rifle that rivals the accuracy of many bolt guns, if I do my part. The SKS in 7.62X39 has been called the updated version of the 30-30(or something close to my paraphrase). To characterize a weapon as good or bad is pretty subjective, don't you think? In my mind, a "bad gun" is one that doesn't work or shoot where it's pointed.
No one has mentioned Armagedden except you. But since you have and if it does come as a battle between "good and evil", do you want your single-shot falling block, or my belt-fed something?
And yes, you and I are both probably self-rightous enough to assume that we'll be on the "good" side in that battle.
