Bolt Not Locking W/ Zero Trigger
Hi!
internals: Zero Trigger Ball Bearing Spring guide laylax hard hop 150 spring B4 I start, I just want to say : When I first got my zt, I didnt know how to put it on the gun. I completely dismantled it. I was able to put it back together(hopefully correctly). I used it for a while. My gun had been having a rough bolt pull. I tried everything, but still rough. So my last thought was to dismantle the ZT and put it back together and see if that changes anything. IT DID. NOT FOR THE BETTER. Now when I pull the bolt back, it WONT LOCK!! I looked at the piston sear and I was just a slight difference in the middle of it. The middle was JUST a little wore/lower and alittle more shinier than the sides on the top. I had the zt for just about 1-2months. I don't think that is the problem, because how it the world will it get like that in 2 months?! Also, the spring guide stopper was originally black, but now the parts that are being touched are silver. Is that normal too? The way I put my gun together, is to put the cylinder first then put the zt because I tie a string on the spring guide stopper so it doesnt get loose. Could that b a problem too? So if you guys got lost cuz of my talking, the main point is that the bolt is not locking when i pull it back and i need it to lock lol I have a game tommorrow! please need to find answers asap |

Normally bolt not locking back = broken sear but if you've disassembled the zero trigger you may have not put a spring back in the right place..
Rough bolt pull can be because a lack of lubrication between the cylinder and the body of the rifle... or if you've got a scope mount (assuming it's a VSR) and you've tightened the screws too far the screws could be causing friction. What company and gun is this? Last edited by Amos; March 28th, 2009 at 17:52.. |

I made an awesome trouble shooting guide that covers this stuff in the upgrade section you should look. I bet that problem is covered in there.

well for 1-2 months its almost impossible to have worn sears. I see alittle curve in te middle of the sear, but its just toooooo tiny to even care about it. Hopefully worn sears(on a zt) r not the problem. Also, i dont think i put anything on the trigger wrong, but just to make sure, do u have any pictures on where the parts belong on the zt? The roughness is also not the lack on lube. Its most likely the sides of the spring guide stopper grinding against the bottom hole on the cylinder. Just duno how to fix that. Thankz alot btw bro |

Since you failed to follow my suggestion I will spoonfeed you. Take your bearing spring guide out and unscrew it. Thread lock the threads and put it back together this should fix it.

hey bro! thx alot for ur help. The troubleshooting guide helped. I think the problem is that the receiver is too thick according to your guide. I just dont understand that the zero trigger was working fine when i first got it for my tm vsr 10. I didnt know how to put it on so i dissassembled it to put it on until i figured out the real way lol. Anyways, it was working fine. Then i decide to take the zt apart again because i tried everything except for that to solve my "rough bolt pull" problem. Ive super glued the 2 halves of the ball bearing spring guide together because ive had that problem in the past. I finally install it in my gun and the first few times i cock it, its fine. Then it gets rougher and then doesnt lock anymore at like the 2 try then it doesnt lock at all after that. Do you think the filing with 100 grit sandpaper will work? Do you think that i didnt install the zt properly? Do you have any pictures that i can follow to install the zt correctly? Thanks alot for ur help I have a game tommorrow and i thought i might not be able to use this rifle but u make me actually have hope lol. Please dont log off or at least check every like few minutes for a msg from me. Really hope i will get to use it tom Last edited by gerardcb; March 28th, 2009 at 20:23.. |

with a TM you shouldn't have to modify the receiver at all...
But I used all PDI parts. Your zero trigger doesn't have anything to do with a rough bolt pull. |

hmm...well then wat else could b causing the bolt not locking back? Isnt it almost impossible for the sears to b the problem because i mean its a laylax zero trigger used for only like 2 months.

there is a little sear that extends on the top of the 0 trigger when you push on it (the way the piston would do) does it locks or it folds?

... What are your cylinder specs? IIRC the Zero trigger has a strangely shaped sear that locks onto the piston... If you're using the stock marui piston the end of your piston may have stripped causing it to slip off... But this is all speculation, I don't have any experience with Zero Triggers (only PDI's V-Trigger) Do a test for me, take the cylinder out and reach in to the sear that'll be in the body, try pushing on it.. it shouldn't move until you press the trigger down. |

cylinder specs/test
Quote:
I took the cylinder out and when i pushed the sear, it didnt move like it should. U know, i was trying out my gun and it worked! it worked for like 5 shots then it didnt lock for about 2-3 pulls then it locked again. I didnt wanna experiment with it more because i'm afraid of wat might happen and the dmg it causes. I gues i might bring it tommorrow on my skirmish, but i really have to have the sniper attitude of one shot, one kill. it prolly wont last for long working. Hopefully it does tho. |

also does the sear try to latch when you are pulling on it? Wonder if the trigger is jammed and lot letting the sear move on order to latch onto the cylinder. |

What do you mean by latch? And what do you mean by pulling on it? Pulling like actually pulling the sear toward you while in the receiver?
