I installed one on my Ruger PCC 9 carbine and it worked well initially but it quickly lost zero and now it seems that adjustments make no difference. The mount is perfectly tight and nothing else is loose or moved. I read about this in a couple of threads but I wanted to see if anyone here has seen this before. Not sure if I want to try another or move to another comparably priced optic? Thanks in advance.
