Fits good
I had to file one little side bur that the machine missed but no big deal it took like two mins but fits perfect now! It's worth it my finger wouldn't fit under my scope with my gloves on to pull my hammer back on my marlin 3030 so I bought this and it's perfect way easier to cock back during rifle season!

Doesnt fit, Marlin .35 reminton lever action.
This doesnt fit a 57' to 82' lever action. I used the serial number on my 35 remington lever action to verify its year. I looked up the hammer designs and it showed images that match the lever i have. Unfortunately theres not enough headspace to go over the hammer. This is the second one i ordered, the first was for the same firearm but later years which made me reference the serial number. It may work for you and i may have something different for some reason. My firearm is a marlin .35 remington lever action made in 1957. My grandfather owned it before he entered Vietnam.

Works perfectly
Finally put a scope on one of my old rifles. I wanted a low profile. This allowed me to adequately put on my scope of choice and still be able to access the hammer with no effort.

Good but could be better
The screws on these are just too fragile and strip too easy . The little supplied wrench is tiny and fails to get a good solid bight thus these things will loosen after a while .

Does not fit 336cr prior 1957
great product for sure. Just make sure you have the right model. My 336c is 1955 and it does not fit. Otherwise it is as expected. Great quality for the price.
