Heres the setup.
6920LE
LT Cantilever mount
Aimpoint M3
LT Troy BUIS
Ammo: tried both 55gr Federal and 55gr Monarch
I was trying to Zero my Aimpoint M3 and also my LT Troy BUIS.
After shooting with just the LT Troy BUIS my shots were shooting low. I'd say 3"+ at 25yrds.
I said the heck with it I'll strap on my Aimpoint and see what happens. Same result was shooting low.
After Zeroing the Aimpoint to hit Dead on, this was the result:
![]()
Is there a problem with my Colt shooting low? I know the BUIS is supposed to be at a proper height already because simply you can not adjust height on it. 2nd Aimpoints should already come zeroed. I'm wondering if there is something wrong with the 6920LE to shoot so low. It almost seems maybe the LT Troy BUIS is to short.
