I'm helping a friend set up a Skinner peep sight on his 94....
He wants a FO front bead but I can't find one that is the correct width...both Williams and Marbels make them in .250 and .340 widths but his in .290....
Marbels doesn't have a rifle specific chart but Williams specifically says the .340 fits a 94..........not..
Tru Glow also makes a 3/8 dovetail front bead but damned if I can find out how wide they are.....

I worry that the .340 will snag on stuff...I could put the .250 on it or maybe change the front ramp but I'd really like to have one that fits the existing ramp (maybe someone changed the front ramp at sometime, dunno)...anyway....are there any mfgr's I'm missing?

Or an even longer shot....does anyone know how wide Tru Glows front beads are?

Thanks
