Thru some trading I have a Remington #5 Rolling Block in 7mm . Got the load dialed in pretty good but plan to in time replace to a tang sight . That little v notch it has got a little small for my eyes and the big thick front sight is no fun either . Has anyone made these improvements to their RB and if so what brand and model sight did you choose ? Measuring for a better front sight do you just measure the upper and lower gap on the dovetail and width ?
