Universal pistol rail adapter and AK-style adjustable sights

This is a pistol rail adapter for all pistols that have a 21mm rail on the bottom of the muzzle.
I intentionally left some space between the pistol and the top-rail, so you can still use the pistol`s iron sights.

The front sight is very simple, but be sure not to break off the thin post.

The adjustable rear sight is inspired by the AK-47´s sights.

All parts have a tight fit because that way they don´t fall of, so a little bit of force is required
(but don´t break it ;D ).
