Anyone have the Magpul MBUS3 rear sight mounted on their ARV?
Having trouble getting mine installed. Says it should fit on this platform. The front went on the hand guard no problem. Any suggestions?
I have seen the gen 3s be tight. A little lube and a rubber mallet may work.

I will try that. It’s almost like the part behind where the screw goes through is out of line with the front portion.
If you have to file anything, do the sight, not the rail.
