Initial disappointment with eagle eye fiber optic sight - TANDEMKROSS Eagle Eye Fiber Optic Sight Set

I wrote a review a week ago and was VERY frustrated with the initial install. After calming down and analyzing the issue I took 600 grit wet/dry sandpaper and sanded the bottom of the Eagle Eye sight. It took almost an hour to sand the black Cerekote off the bottom of the Eagle Eye sight. It took time but it eventually slid in and I thread locked it in and started banging' and it took very little sight adjustment and I was slamming my 5" discs in my little range. NOW I ordered another set of sights for my next TX22 and have yet to install them now that I know how. I am a happy man now that I can see my sights. I'm over 70 and need the quick pick-up I get with my Eagle Eye Fiber Optic Sights. A wonderful sigh of relief. Great Product!
