source for OEM 617 rear sight?

[markush]

I'm considering purchasing a 617-1 that has had it's rear sight removed to install a scope base...original rear sight not included.

A quick google search hasn't turned up a source or cost of an OEM replacement. Would this only be available from S&W? Can someone give me an idea of what a new rear sight would cost (saving me a phone call)?

Brownell's has it, or you could call S&W.

I don't know if the 617-1 has the old or new style rear sight.

The 617-1 has the new-style (round-leaf) rear sight, and is drilled & tapped at the factory to mount a scope base. Any new-style rear sight assembly should work.

Thanks! Brownell's of course . I tried Numrich and didn't see the complete assembly just the individual parts...Thanks again.

.136" or .146" does this refer to the notch opening size? What was OEM on a 6" barrel?

 

[Tom C]

No, I believe that is the blade height of the rear sight. I am not sure which would be appropriate for your gun. It depends on the height of the front sight.

 

[valkyriekl]

correct--that refers to the height of the rear sight blade. According to my copy of the Kuhnhausen shop manual, S&W didn't vary the depth or width of the notch, just the height of the whole blade.

My 617-6 and 617-4 and 17-8 (all 6" K-frames with the small (0.200"?) Patridge front sight, and all of which have the new-style rear sight) came with 0.146"-high rear sight blades. Both of my Model 14s (6" K-frames with the medium Patridge front sight (0.250"?)) came with the 0.126"-high rear sight blades. I think I actually prefer the 0.146" sight blades.

It depends on how much rear-sight elevation you'll need--if you're shooting Bullseye with iron sights and a 6-o'clock or sub-6 hold, you might need a taller sight blade (just so that the rear sight body doesn't float so high over the frame). If you're going for a center-hold, a shorter sight blade might be more appropriate.

This was what I found.

HaHa seems just a tiny bit overkill for a .22lr Maybe for a M29?

617's have oddball sight heights. .167 front, .126 rear, if I remember right. You can usually run a .228 front with a .196 rear. The tallest rear blades (.160 and .196) have the deepest notches. The notches get shallower as the blade heights decrease. I run a .228 front cut down to .200 with a .160 rear.
