I am looking at one of these http://www.youtube.com/watch?v=Nh0fIIA77bw&feature=player_embedded I am not able to own a SBR in the lovely state I live in and do not want the extra 10" of can sticking off the rifle. Pretty much have all the parts needed for the upper build just need to send it all in and have them get started. I also might have to get another can for the MaTen and another .300 black that I have. Who can have just one :))
