After the recent prarie dog post, I have got an itch to pick up a used AR15. I own a decent selection of rifles, shotguns, and hand guns, but I would like to pick up a better varmint gun.
In the 80's I was in the Army reserves, so I think it would be fun to have an AR15 of some sorts kinda for old times sake.
I have heard of Bushmaster, Colt and another brand. For my purposes, any brand will probably do, but I can't justify blowing $1000 bucks on a gun right now (like I said, I have quite a few all-ready). Where is a good place on-line to shop for used guns of this type? What is a low price for used one?
