So here's how it works ... I think.
I'm still working with it to see if I'm doing it right and understand how it should work.
You pull out the original sight leaf and spring. (Oh what joy that task is!
)
Then insert the "t"-shaped front prong ears into the ears of the trunion.
Insert the long dowel pin (
A) through below the front prong of the mount, and tighten the set screw (
B) that jacks down onto that pin to hold the mount up firmly into the trunion ears.
Here's where it starts to get a little questionable, to me. You then use the rear jack screw (
C) to press down into the base of the original sight mount to elevate the rear of the optic mount. That screw will hold it UP, but there doesn't seem to be any real force holding it DOWN. So, it's not real hard to lift the rear of the mount and screw up your elevation setting.
You screw in the two cap screws (
E) at the sides and they sort of grip the outside faces of the rear trunion. But they can't do much more than very minorly secure it, because if you tighten them much the heads slip up and off of the trunion sides and push the mount up out of place. So, it seems they need to be not a whole lot more than finger-tight and held in with locktight. I thought that maybe they were supposed to try and hold the mount down, but any real tension there actually pushes it up out of place. So I'm a little confused by that.
Letter "
D" in the picture is a sliding dovetail between the steel front half of the mount and the aluminum rear that actually holds the optic. There is a set screw you can't see in this picture that secures them from sliding. This gives you a simple windage adjustment for the built-in rear sight notch (
F), and to roughly center the optic.
The instructions say to use that rear jack screw (
C) to roughly set the mount's elevation until the bottom of the mount is parallel with the top of the dust cover. I did so, but what my eyes told me about that was WAY off from where it really needed to sit.
That's not much of a surprise, I guess, as AK dust covers are not a precision part and aren't held in place with any sort of precision. I'm not worried about that elevation factor, so much as the fact that it seems too easy to bump the whole mount upward and lift the rear of it up enough to shoot way over the heads of the targets.
