| I got a mil-spec rear sight to replace the silver colored sight on my Krebs AK103K conversion. It looks like it should fit easily. However, Im not that familiar with AK assembly. Any tips on how to get the old blade out easily with screwing anything up? |

this job is best done with 4 hands. call up a friend and have him help. first, flip the sight leaf up to about a 60° from horizontal angle. under the sight leaf is a flat leaf spring. using a screwdriver, depress the spring in front of the pivot point of the sight leaf. this will require a lot of pressure!!! one slip and injury, or at least lots of swearing, is possible. puncture wounds suck! let your friend hold the rifle securely and press down on that spring. while he takes the pressure off the sight, wiggle it on a side-to-side angle tp get one of the pivot posts into the large part of the keyhole slot in the sight base. now, careful twisting will worm the sight leaf out of the base. installation is just the reverse of this. another option is to modify a c-clamp...thinning down the clamp screw and blocking the receiever bottom with a thin plate of steel to clamp against. i have also heard of guys that used a wood golf tee, driven by a c-clamp to depress the leaf spring. |
 Campy, Did I mention that being Italian and Dutch = Stuborn and Stupid? I went ahead and did it anyway. Used a Saf-T plastic 5.56mm/.223 round and the floor to depress the detent spring plate. Popped the sight right out. I used the pivot pin guides and snapped the new one right back in. No puncture, but a nice rear blade slice. Oh well, Im not gonna die, and its done.

| If you got a drill press it is easy, mount rifle in vice, chuck up a drill rod and position it so it will contact the leaf spring (with sight leaf up). With drill off bring the drill down onto the spring to depress it, and remove sight. You are just useing the drill press as a Press. It works great, and no bandaids needed. |
