Recently the spring that returns the sear on my Zero Trigger broke. This caused a small panic of "Oh great, 500+ rounds later and my $200 trigger is done." I decided that since I might have to send it off for repairs why not take a shot myself? To make a long story short I'm glad I decided to try it myself.

First thing you want to do is remove all the hex screws from one side of the plate. Gently and boy do I mean gently separate the two plates. Yous should be left with something similar to this, if the pillars or rings fall off don't worry I'll tell you where to put them back.


Go ahead and remove everything until your trigger looks like mine. Don't worry no small parts will fall out just pillars and rings.


Now slowly pull the sear assembly off the plate and set it right side up. Take a look at the picture and remove the ring and the pillars that are displayed in the picture.



The back section of the assembly should be like this with the pillar removed. Now remove the bottom pin, note that this pin is a different size so you need to keep it separate from the others. When you push this pin out the two plates should fall along with the spring.



Reassembly time. Grab the sear assembly and the first plate along with the special pillar.


Now the spring, then the last plate.



Now grab a ring and put it in between the plates and stick a pillar through them.


Ok before we starting putting things back together we need to add the rings that we can't put on if we assemble others things first.
Here's a key to help understand the picture.
Green = Ring
Red = Pillar
Yellow = The two pillars on the sear and the back of the sear assembly.
Gold = Trigger sear pillar.


Following the guide you should be able to get to this part fairly easily. Please note that when installing the spring guide look which way the notch is facing and that it sits on top of the rings. Also the two rings that are on the sear assembly.


Here you can see a final picture of assembly with all the springs attached to the personal pillars. This part gets pretty tricky since everything is under tension so taking your time is key here to not have everything explode on you. If you can get everything in place without holding it simply put the plate on top put a ton of pressure on it and move the pillars with a small screwdriver to align them to their holes.


If you anyone has any questions or if pictures expire let me know and I'll help and or update the pictures. This link will take you to the album for the guide that includes some more up close pictures for people having issues with the final assembly.

Parts for your LayLax/AA trigger can be purchased here. (Thanks to 1tonne for the link)

If anyone ever needs parts for either the Laylax Zero Trigger or the Action Army Specialized Trigger, they can go directly to AA and they will send the parts normally just for the cost of the freight. These 2 trigger systems are exactly the same as I have owned both and I have fixed the Laylax version with AA Parts.

This thread would be good to sticky as I have a lot of people asking me for photos of how to pull apart their trigger.

Duuudee, thanks a lot! My sear spring just snapped in bottom area and my piston sear can't return to its original position. I did your instructions step by step (also with cleaning and lubing those dirty parts), and i just stretch the broken spring and coil it so it could engage with the pillar. And it works!

Cheers man, i can't say thank you enough.

I swear they must have swapped to cheaper parts over the years on the Laylax Trigger. I have one each on my Maruzen L96 and my VSR G Spec and both are at least 10-15 years old. Never had a problem.

So would you recommend buying a AA zero degree trigger set over a Laylax since they have the same parts and the AA set is cheaper?

I had to do this in the field once at a big op on the back of a pickup tailgate . Salvaged an AEG tappet plate spring and cut and bent it into the right length. Talk about a panic moment , it was the only gun I had up for the whole weekend
I bet you were praying the parts did not go flying off the tailgate!:yup:

Hello Accurate,
I just ordered my AA hop up, AA 6.01 barrel and ML bucking. Thanks for the advice.
I was about to post about zero trigger sets and came across this thread. Army Action or Laylax?
From your post, it seems like Laylax has dropped in quality, so why pay more money than the AA set?
Plus if the parts are the same.....

They are about the same quality. Can't see any difference really. So why pay for the more expensive one.

That is what I figure. Best to order a few extra springs with the set.

What about the PDI V-Trigger or the Springer S-Trigger?

I was also wondering what Novritsch uses in his SSG-24 and whether they break often too.

You would think that if the manufacturer's used a stronger sear spring, that would solve the problem.

I wonder if most of the people having the problems are using a stronger +500 fps spring as opposed to those using a weaker 450 fps spring?

To answer one of my own questions, I was just at the SSG-24 forum and apparently batch 5 of the SSG-24 has some trigger problems.

The spring breakage for the Laylax and AA is not a regular thing. It happens only about once every 15,000-20,000. So that is about 5+ years usage for most regular players.
You could get some spare springs but it is an easy fix with a pen spring and then you have another 5+ years again.

Does the laylax fit better?
Just wondering if the AA trigger kit has been upgraded or do you still run into the same problems installing it into a Bar-10 as seen in this video made a few years ago?
