Posted this same thread over on the Greybeard H&R forum looking for answers...
I put a Williams WGRS rear aperture on my HR. Combined with that, the factory front sightwas way too low. I (partially) remedied that by soldering a section of 16-penny nail on top of the front sight, then filed the sides down flat to match the blade and dressed up the rest of it as needed. Now don't laugh! It worked...after a fashion anyways.
But I'm not really satisfied and want something different. Trying to find a suitable ramp that has the right contour for a .798" diameter barrel is not a simple thing to do. I've looked at all the major sources: Williams, Marble, skinner, brownells, midway...can't find what I'm looking for. None of the ramps have the screw hole in the right place (there's only one on the HR - and I don't really want to drill another hole in the barrel).
Anybody here dealt with this before? What do you suggest? I can do some of this but drilling holes in my barrel...no thanks. And I prefer not to $pend money on a gun$mith...if I don't have to.
