When I shoot or manually cycle my AK, the rear sight leaf spring will walk out towards the muzzle, causing the rear sight to flop around loose. I can slide it back in place but it does the same thing again.
Anybody have a fix for this? Is there something I am missing? Thanks. |

Quoted:
I am pretty sure its just a detent, mine is at least. Mine is very light and may not be deep enought to engage the hole in the trunion. That may be your problem; the detent is the only thing holding the leaf spring in place, besides the tension it puts on the rear sight leaf itself. Maybe you can take out the rear sight spring and bend it a little to create more tension to hold it in the detent. One of my rifles had a weak spring and I bent it slightly in a vise to create some more tension, but mine wasn't walking out though. |

There is NO weld or pin.
Your tension spring is probably weak or bent as mentioned. The easiest way (relatively speaking) to get the leaf out is to press down using some sort of HARD plastic (or brass) tool at the base of the leaf sight where it pivots in the rear sight block. You will need to press pretty hard, and you may want to wear gloves so you don't gouge your hand. While pressing down on it, press it towards the rear of the rifle. Eventually it will pop out once the pivots of the sight leaf clear the indents in the rear sight block. Once the rear sight is out, you will be able to see the spring. It should have a decent arch to it and should be stiff when you press down on it. To remove the spring, just pull it forward towards the front of the rifle. It should pop out of the small detent in the rear sight block. You may need to use needle nose pliers.

Looks like you're getting a crack in the rear sight base right where the leaf tension spring goes.

Nope just a random google image and honestly I didn't notice the crack! Probably what the photo was trying to capture. Glad it's not yours, that's not a real easy fix. OP - It does sound like you have weak or bad tension spring. Don't try to bend it while is's still in the rifle or you may crack yours too. |
