Tack, I shot mine as a pistol for a while... it's different, believe me. In a pinch it's fine, but more shootable as a rifle. I like to keep things the same ,so I like the SBR setup.. but you are right...it may work for you if you shoot the stock all the way collapsed, of it does, good for you, save the cash for hookers and blow !
Dale, as long as I have my ATF paperwork with me as required, there is no problem that I am aware of unless I am planning of going to Chicago or similar...if you know different, other than this guy heard some dude tell this girl at a bar... I'll need a cite....
