Does anyone know which Lyman 66 style sight will fit the 1895...if any? Any experience or alternatives would be appreciated.

10at6, I`ve got a Williams peep on mine don't know the part No but it also fits the Win 94 models and the Marlin 336. there are two types the non mirco ajust and the micro ajust which is the one I have,, Les

I put a Williams WGRS for the Browning BLR on my Guide Gun. I filed the bottom of the sight a bit to flatten it to fit Marlin. Hole spacing is the same. Makes for a very compact sight. Up front I have an Ashley Patridge with a white vertical line. Pretty amazing how well this combo shoots out to 200 yards.
