Tuning Edgun Leshiy 2 250mm .22 cal ISSUE!!!

Hi, it appears I am having an issue with my L2. When shooting,

this lever (see picture, my finger is pointing at it) is somehow disengaging and the stock is popping open ever so slightly. This happens almost every time I start shooting. I shot with a bipod and on bags and the issue still persists. Anyone ever seen this issue before? 
 
I just checked mine. Sounds like your tapered locking pin isn’t going into the hole of the lug far enough. The tapered locking pin locks up the action and on mine it doesn’t take much movement on the lever to disengage and open the action. Only about 1/16” . I would like to have more myself but it does lock and I can’t make it open without pulling the lever. When closed the lever doesn’t go all the way down compared to when the action is open so the pin is either bottoming out in the lug or it isn’t centered in the hole. Check your lever throw when closed and when open and see if the pin is going down all the way when closed. There is an Allen screw and a pin holding the silver lug, see picture. Maybe if you loosen the Allen screw the silver lug can be adjusted in and out to align with the locking pin. I would loosen the screw, close the action and see if that helps. If it does then tighten the screw and you should be good to go. This is just a guess. Please let us know if this does it.

I have a caliper and measured the pin that comes out is 3.42mm. How far does yours come out? Once its locked it won't unlock unless I shoot the gun. I'm wondering now if there is a manufacturer flaw and I don't want to break warranty. I probably won't mess with the reg unless told otherwise. Its issue is nagging and becoming frustrating. It shouldn't behave this way.

Wow that video concerns me as I said my leaver only moves a tiny bit before it unlocks the action. The fact you say it won’t unlock unless the gun is fired really confuses me as it is just a simple locking devise. Is the leaver Jammed tight when closed? Or can you still move it. If you can still move it then the tapered pin must be broken. Definitely call Brian at EdGun West and he will take care of it. Good luck
 
So I decided to tinker a bit more and see if I loosened the screw, part #16 at which point would the gun cause the pin to disengage when firing. As soon as I got it to a point where it actually functioned normally, moving the lever and the pin operated normally, it started working properly. I test fired it over 20 times with ammo and everything is working normally now. Not sure why this is the case but it is.
