Custom 90� VSR trigger

Custom 90° VSR trigger (S-trigger)

LATEST VERSION S-trigger v.7

I hope that you don't forget on my S-trigger :).

It takes me some time to figure out what I want from the new trigger.

It is mostly:
  • Preserved safety function ( its challenge in this design )
  • Zero need of modification to the gun or trigger guard ( my priority )
  • Simply as possible
  • Robust and durable
  • Versatility ( TM VSR/TM L96 in one package )
  • Some adjustability ( length of trigger pull )
  • Light trigger pull ( even better than on last version )

I have prototype of a new S-trigger v.7 on which I am testing above-mentioned.
Its not the final design, needs some tweaking but is not far from that.

How much I wanted to makes it different from ZERO trigger. I spent a month by trying to make it completely different :) In the end its almost from 30% Zero trigger. Internally its almost completely redesigned. Less complex and easier to manufacture.

Stay tuned for news

Info for Older version of the trigger ( v.6 ) below in code
[B]For[/B] these who don't know my trigger , I call him [U]S-trigger[/U]. Functionally is based on Noobies M-trigger. So if there anybody who still trying to find some M-triggers for sale , I can offer you my S-trigger which has all features of M-trigger and something more.

[B]Advantage[/B] of my trigger beside other after market triggers is preserved function of [U]safety[/U] [only my S-trigger and V-trigger has safety].

For example on stock JG BAR-10 spring is trigger pull weight on my S-trigger [U]1,5 lb[/U]. and on V-trigger [U]4,5 lb[/U]. 

[B]It[/B] is simple 90 degree design focused on durability. All steel construction of trigger is ready for strongest upgrades available on market.

Ill email you back by this weekend to let you know when I can order one.
Thanks for the quick reply.

Edit: just to confirm my piston will work, I have an Edgi piston, have anyone ever used one with your s-trig?
Haha are you selling those already?
Just placed an order! i'll make a review as soon as i test it out. Cant wait!
Nope he shipped mine the day I paid. Fast response too.

Initial impression:
Everything looked perfect and more durable than the stock trigger box 100 fold. The material is sturdy and the screws aren't coming out by themselves, that's for sure. One thing I noticed was that the spring guide pin was connected to the actual trigger box which is a nice feature. Overall, it's a well built, durable, universal (you'll see why in a second), sweet looking trigger box.

In comparison

As I went to install, I filed the trigger guard down like mentioned in the instructions. Once it fit, I put my Laylax Teflon cylinder in the receiver and then screwed the trigger box down and then the trigger guard. Everything looked ready to go. I assembled the rifle, pulled the bolt back and nothing... It wouldn't lock in place. But I was determined to figure out why. So I started trouble shooting and the problem was not the s-trigger. The problem was the spring guide. Unfortunately, Edgi's spring guide didn't work with the Laylax piston. This is because the Laylax piston was too short and the spring guide didn't go in all the way. Here's some pictures so you can see what I mean:

This is with the spring guide in:

As you can see, the edgi spring guide is a bit longer than the stock.
This doesn't allow the trigger sear to catch the piston which is why it wouldn't lock.
Thus you have two options, grind the edgi spring guide to the stock length. Or you can get a new spring guide that's stock length.

But!!! Being persistent pays off. as I looked closer at the edgi piston, it looked different than other 45 degree pistons. Yes it has a 45 degree edge on it but it also has a 90 degree on the inside of the ring. Making it the first, unintentional or intentional, I'm not sure, hybrid piston!!! So I decided to test it out, I put the edgi piston, Laylax m150 spring, and edgi spring guide into my Laylax Teflon cylinder. Installed the s-trigger and assembled the rifle.
Sure enough!, it worked like a charm! I even jiggled it around to see if it would slip off but it doesn't. I will continue to test and see if any damage is done to the piston or the trigger. But as of now, I just got really lucky hahah.

Let me know what you guys think or if you have any input!

Springer for your website review:

Overall, the s-trigger has exceeded my expectations. The high quality, durable, and sleek finish has definitely won me over. In comparison to an upgraded edgi stock trigger box, the s-trigger, hands down surpasses the performance. Money well spent and worth every penny. I would highly recommend this to anyone who is looking for custom top quality products for their bar-10!

Nope they told me they stopped producing vsr-10 parts for now,
Because of the HPA.
Custom 90° VSR trigger

Unfortunately, my s trigger broke tonight. I temporarily fixed it but its definitely the u shaped spring that holds the sear that is broken. I will discuss it with springer.
How many round's have you fired with it ?
I'm a little over 9000.

What spring were you running?

AUDREY-As a first post, you deserve to be kicked. Lame.:bs:
M150 Laylax
Damn is that it was just a spring that broke? I'm getting ready to buy one. I've fired over 4000rds with stock box and upgraded sears with a 170 and no problems.

Does Springer offer spare parts if anything breaks?
Yep he is very generous.
Just put an order in for two more!
