The receiver hole spacing is the same for 336 and 1895 - so yes, the receiver (peep) wil fit. Something to remember, the adjustment range on the WRGS peep is 0.100". If your front sight is too short, you will run out of adjustment room. If it is too tall, you can shim the peep. Hopefully the folks at Williams can send you the correct front sight height first time. One more thing, you may find the stainless cutout hood used for the stainless Marlin 60's to be less obtrusive to shoot with than the blued hood. Stainless seems to dissappear to my eyes.
