No problems with function for 160 rounds. I marked the wear areas and there is no longer any contact.
Good news!
Thanks, RSR. I now need to do the others and pay close attention as the rounds add up. I'll update if anything happens.
I got the AR rear-sight stock adapter from Czechpoint and will be installing it in the next couple of weeks. The home-built aperture sight has cut my groups in half. I've been getting ragged holes at 50 yards and about 5-6 inch groups at 100. Room for improvement at 100 yards. I can finally see the target clearly instead of a black blur.
