New vsr problem...

When I say new problem, I mean I can't find any other example of this in this forum or on Google....

So here it goes.... I bought brand new TM vsr 10 pro sniper and all action army internals.

The first problem I had was the 90 trigger release sear seizing in the forward position when fired resulting in the rifle only shooting once and was unable to recock because the sear was stuck down against the edge of the oval opening of the cylinder housing... So I read the forums here and I filed down the long oval opening in the bottom of the cylinder frame to allow for free movement and of the spring guide sear and the trigger release sear.

That seemed to fix the problem...but now when I rotate the cocking handle up to load a shot, the cylinder itself twists a bit and won't allow the sear to grab the piston (unless I manually twist it back)
My only thoughts are that I over filed the oval opening allowing for too much play, or the long sear is loose and moving left to right, mis-aligning the cylinder.

I am considering to try and get another cylinder frame outer body to start from scratch....any other ideas?

Is my terminology alright? I wasn't sure the exact name of the two different Sears or the name of the body that holds the cylinder.

Its cool, if im wrong someone will correct me. (Most people have their own terminology but we know what each other are talking about for the most part.)
Receiver = cylinder housing
Spring stop sear = long sear
trigger sear = small sear, catches piston

Make sure your teflon cylinder guide rings are still in place, should be 2 in the receiver.

Does it fire consecutively a few times? you say you filed the spring guide sear cylinder spot? you want that sear to fit snugly into the cylinder and stay it shouldnt be free moving.

My rifle's trigger sear would lock up, what I had to do was shim the front screw of the trigger unit to make it hold, and also used loctite. Also my spring guide sear i sanded too much and i used electrical tape to hold it in place and it worked fine.

If those dont work possibly might need a new receiver. Hopefully this or someone elses opinion can help you out.

It does sound like you filed it a bit too much. When filing it, you want it to only just fit in without any movement. So the spring guide should be able to move back and forwards without gripping the cylinder. The trigger sear can also have the same issue.
Another way of fixing it is to file down the sides of the spring guide and trigger sear.

This was basically my route and i ended up reordering and breaking open the trigger unit. real PITA so when you get to sanding be cautious. lol

Thanks all for the info, this is truly the best forum for airsofters...

I tried to tape the spring guide sear but it still has a bit of side to side movement.

I decided to just bite the bb and order a new maple leaf one piece receiver (~60 cad), I hope it solves the problem... otherwise I may have also over filed the spring guide sear itself.... in which case I'll reorder one of those too.....

Yeah possibly too much on the receiver, because if you taped the spring guide sear to the top part of it, it should be secured. When you try to pull the bolt back after that and its moving side to side its the receiver.

When you get your new receiver and it you start having fitment issues sand down the sides of the spring guide sear, leave the trigger sear alone! it will be a PAIN but be patient with the sear. alot of taking the gun apart and putting back together but worth it.
