Hi! I've been wondering why my TM VSR-10 G-Spec's bolt doesnt lock.
The Zero Trigger was jammed. I took out the bolt/cylinder to test it.
I pushed the sear then pulled the trigger. It folded backwards,
but it stayed folded. It doesnt naturally go back unless I pull the sear back manually. Sometimes it does this and sometimes it doesnt.
First when I got the ZT, I took it all apart because I didnt know how to put it on my gun. I was able to put it on my gun then I figured out how to put it on the right way

. I think I put it back together correctly, but the bolt pull was rough.
I took it apart and put back together again to try to solve rough bolt pull and It started not locking.
How do Solve this problem? Anyone know if and what part of ZT I put on wrong?
