Picked mine up today! Holy shit, this thing has heft!
Question though.. I think I might have accidently snapped something in the rear sight apature

. Anyone know how that metal pin in there is held in (it's curved, about an inch long, two holes in one end). It "pranged" out when I bumped the rearsight by accident.
EDIT:
It also seems my selector switch only works when it wants to. Sometimes it does nothing. Anyone else have issues with it?
