okay, before I lose it, help me out guys! I had to take off the sights on my m14 to mount a scope, but now that I want to put the sights back on, they knobs are jamming up. They worked beautifully before though. When I assemble the sight, the flat on the thread on the elevation pinion catches a flat in the windage knob and makes it so that both know turn at the same time, I have tried figuring it out but am at a loss..... Am I missing a part here or something
?
