So, these past few times shooting, I've noticed my sights looked a little off... Well upon closer inspection, my rear sight on my springfield GI is loose. It's the GI style low profile non-adjustable sight. I can press it back into place against some wood or plastic, but within a few shots it bumps loose and i can wiggle it with my fingers. maybe wiggles back and forth about 1/16th of an inch, enough to screw up my patterns at 25 feet, haha. How can I fix this, if I press it in too far it'll be out of alignment, so i cant just do that, it wiggles around where it should be sighted in. Is there anything I can do? I dont wanna put loctite on it or anything...do I need to take her in to a gunsmith? I'm not sure how to work this out.
