The specs for the new Dreamline Compact Tactical show it, and the "extended" version to both have a 500mm barrel in .22 caliber. Does anyone out there know the correct specs for the compact (not extended model)? The picture appears to preclude the possibility of a 500mm barrel in the compact non-extended version. To my eyes anyway. I really hope that the barrel is short and has a fixed, fully functioning shroud/moderator.
