Does the same sight fit a win. 94. ?
No. Williams FP-336 only fits the Marlins using the top mount holes and often necessitates replacing the front sight with a taller one.
The FP-94/36 WILL fit the Winchester 94 and Marlin 336 using the holes in the side of the frame. Sits a little lower and usually utilizes the factory front sight w/o issue.
