I had be using a low profile claw mount on my HK SR9T that required me to take of the rear sight. I picked up an A.R.M.S. Claw mount for the HK SR9T that is supposed you use the rear sight and has a hole thru the mount to let you do so. I re-installed the rear sight be after trying may times to install the A.R.M.S. over the rear sight it just would not fit over it. It looks like there is not enough clearance to fit over the sight. I don't know what I an doing wrong.
Am I wrong in my assumption that the mount allows you to use the iron sights as well as a scope or am I doing something wrong?
Any help would be greatly appreciated.
TIA
