So I purchased my Velocity Arms M4 on thursday and frank gave me a new iron sight to use for it, just wondering how exactly I take off the Triangle Sight. I've removed the bottom pins as well as the screw in the back of it thats connected to the rail plate, but there seems to be another screw under the clip that holds a strap and I can't figure out how to remove it. Any help would be hugely appreciated
