... I need help locating a rear peep sight for an 1894S marlin 44mag. I'm looking for the one tha attaches to the top of the receiver via the factory scope base holes....
You may be thinking of the Williams -336 series (5D basic, or FP with micrometer adj.) I just put a 5D-336 on my 1895. I think the scope base holes are the same, so it should fit an 1894 as well. According to the Williams catalogue:
5D-336: For Marlin Centerfire Lever actions (uses two rear scope mount
holes) 1894 requires hammer extension.If in doubt, give Williams a call (1-800-530-9028)
The WGRS is good, but you have to remove the aperture to get access to the screw to adjust elevation.
I have not used the XS sights but everything I have heard has been very favourable. I have made up my own "white line" front sights in XS style, using a
very thin strip of white Scotchlite reflective tape on the front of the blade and find they stand out really well.
