Nice Aimpoint. I thought about getting one for my shorty, but mine has the carry handle on it. I guess it would still work ok being way up there above the bore so high. The little Chinese scope I have on it now seems to hit to point of aim fairly well at 40 to 100 m.
get a cantilever mount so it's not so high above the bore.
