Was able to successfully install a new rear sight on my SMR. I already had a taller sight on it but I’d messed it up from the get go. When I was shaping it I made one too many passes with the file so I had to shim it with .005” copper, then when I was sighting it in I again got over jealous with the file and got it shooting a little low. Could have just filed the front sight a little, but that would have defeated the whole purpose of getting the higher sight picture I like. Yesterday I tried heating the old one up and peening it out and I filled the V up with some silver solder and reshaped it. I did manage to peen out the extra length but the base took a slight bow that I couldn’t get out so I said the hell with it. I keep a couple of extra TOW tall sights on hand, I’ve used these on the SMRs and Woodsrunners. Today I took my time and got a good tight fit. But I’ll be dog gone if I didn’t almost get the V too deep. I’ve learned to start with the bottom of the V at .220” above the flat, which prints 2”-3” high at 50 yrds. The sight I messed up was filed to .210” and was low at 50. Although I called myself stopping high on the V filing, once installed it measured .215” above the flat. So fingers crossed that it’s spot on this time. For comparison the factory Kibler SMR rear sight V measures .114” above the flat. I had to file the front sight down to a nub before I swapped to the taller ones.
