Lyman 57SA Rear Sight?
I just picked one up for my Savage 99 project but doesn't include instructions. Just curious to see if anybody know where I can get one.
Thanks!

Re: Lyman 57SA Rear Sight?
Just a couple of questions:
The hash marks on the windage and elevation settings, what do they represent?
There are a couple of screws, one on the elevation side plate, one on the windage plate and a long set screw near the elevation knob. What adjustments do they make?

[The hash marks on the windage and elevation settings, what do they represent?]
They are called "gradients", and theoretically represent different distance settings - but don't rely on them to be accurate, since settings vary rifle to rifle and with differing chamberings & loads.
[There are a couple of screws, one on the elevation side plate, one on the windage plate]
[What adjustments do they make?] - None
These screws secure the gradient scales (marker plates) to the sight body, and are usually centered/zeroed after the rifle is sighted-in. Then, theoretically, a shooter can twirl a windage and/or elevation adjustment so many gradients, and expect to be zeroed at some other distance. I ignore them, after centering them for "looks".
[a long set screw near the elevation knob.] - It is a "return to zero" feature, used when removing the upper half of the sight, say to use a scope or whatever. This is backed out until the rifle is sighted-in/zeroed, then screwed in until the tip just kisses the top of the action. Once you do that, the side button on the base may be depressed to pull out/remove the peep cross bar - and the peep will return to zero when you pop it back down to the limit set by the screw (provided the screw hasn't been fooled with in the meantime).

That's as good an explanation as in the instructions and Lyman includes pictures! Thanks Pete.
