OK...
ASA flattop upper. RRA post-ban stripped lower built by me with JARD trigger (set at 16 oz.), JP anti-walk pins, extended oversize mag release (modified spring), extended bolt release, Badger Ordinance tac-latch, ASA one piece mag block, and Hogue grip.
Buttstock is FIXED in short/mid position (from Model 1 sales) and fitted with Colt heavy buffer. Comp is from EGW gunworks. It is post-ban legal and has been blind pinned onto a threaded barrel that was shortened so overall length WITH comp is 16.25 in. (left a .25 margin for error just to be safe.)
Tube is aluminum free float (mainly to add weight up front and look cool). Sight is C-More SlideRide on an A.R.M.s #44 throw lever mount.
Shoots VERY sweet. I built it to compete in IDPA style three gun matches our club holds where target distance never exceeds 20 yards and moving quickly around barricades and barrels is made easier by this EXTREMELY compact gun. I also have a very similar looking .223 Bushy for farther range...
