lost the front sight on my .54 t/c renegade on the next to last day of pa flint season.ran to my local sporting goods shop and picked up a rmc sights kit for it.instead of going home, I drove to the rifle range to change the sights and re-sight in.while I was changing the rear sight on the bench, a gust of wind caught the plastic box the sight was in. lost the screw that holds the rear on. emailed them when I got home (had to change guns) and 5 days later a envelope arrives with 4 screws in it. no charge. not even for postage! I know where i'll check for parts for my guns now!
