Took some thinking but I mounted a ATI Heatshield Ghost Ring Sight Combo to my Rem 1100, Required to shave the top off the forearm (paid 20$ for it) I put it on a belt sander and shaved the front down a few mm's, then I had to make a notch on both side so I could fit the clamp that goes around the barrel, I had to align it so it would not effect the moving parts and bent the tabs around my gas port area....
This was a prototype I'll be getting another forearm and modding it so I wont have to make notches in it and be able to remove the forearm w/o taking off the shield.
