I bought a set for my model 70 (magazine fed version of the model 60) and my 11 year old son loves them. I changed the 70 to tech sights and a they currently reside on a 60. Easy install, easy to adjust and work well. Much better than the stock sight.
I'm sorry! I wasn't very specific in my question! I thought you could read my mind. I was talking about the gun sight. I've been thinking about getting one for my Levermatic, and was looking at the 'Ace in the Hole' front and rear sites. For $68, it doesn't sound like a bad deal. Then I could take that scope off. I wish I knew someone with a peep sight so I could try it out and see if I can focus the front and rear sights at the same time. Getting old has some serious drawbacks!
For a peep option, I have the Williams WGRS-54 that would fit on the dovetail on the Model 60 receiver, however you would probably need a taller front sight. I used this one on a Glenfield 25 that has the dovetail slot in the barrel for the front sight, just drifted out and replaced with a taller Marbles front sight. If you have a screwed in front sight, there are screwed on ramps that can take a dovetail insert and you can go as tall as you need.
Gumpy yup I misunderstood your question. I just have the standard sights always had trouble with my vision. I saw some youtube vids on the fire sights snd I was really interested! I still plan on a decent scope with some see through sope mounts!
