Now this is purely for the M54 Win. It has the goose egg rear site boss on all eras, but the later ramp identical to the integral ramp of the Win 70 is later. The earlier M54's had front sights similar to 1898 Krags. I do not know the heights of either front sight with or without the ramp or the heights of the leafs on the Lyman 6W for that matter, but the ranges for the M54 with the 6W is 200 yards and 500 yards!
