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
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. 

[U][B]Trigger pull weight[/B][/U]

Average trigger pull weight on my S-trigger is 1.5 lb.

Another update my s-trigger is up to 53.5k as of this weekend. Still using original piston sear.

Anyone compared this to the Laylax PSS10 Zero trigger?
Can't decide between Laylax Zero trigger and piston, or S-trigger and Ranger's piston. I'll probably go with the latter. ;)

What do you expect from trigger ? You can write here functions which are important for you and I can help you decide.

I also send one trigger to Daren from ASPUK, tels me that he used almost every trigger so when it will arrive to him , probably makes some review.

I own ASG zero trigger (its different shape but same function) so I have some insights.
Just looking for a sturdy and reliable trigger that will survive for a long time in a gun shooting at 450fps (on .2g).

Decided to go with the S-trigger though, when I get round to buying a trigger anyway.

I have'nt had any other zero triggers, but I will say that these S Triggers are bad ass! just received my box of 10 trigger units from Springer today, and I cannot wait to install mine!

Not trying to "sell these up" but in my opinion, buying from a small business like Springer and myself tend to care more, and take better care of our products, and customers.. Without you, there wouldnt be us..

The big companies dont usually care as much. There will be better customer service, and replacement parts etc..

Everyone knows the issues with the M28, and I cant imagine Echo1 not knowing about it.. BUT, all they have done so far, was call us owners idiots, and say the rifles are fine, and that all these stock pistons blowing out was OUR fault.. Brian from E1 has a youtube video where he talks crap to us, and is super snotty..

I can tell you right now, if there were to be a problem with my parts, or Springers parts, we would make sure you "the customer" is happy.. I know that Springer feels the same way, cause as soon as I mentioned modding the trigger box to fit the M28, he was cool enough to make another style trigger box that will fit the M28.

Right there shows me he cares, and that he's a good dude.. If anyone ever has a problem with my custom parts, I will do everything I can to make ya happy, as I believe Springer would also do..

Not saying them other trigger boxes arent also awesome, cause they must be cause they sell like hot cakes lol.. But, them guys will never be personal with a customer like us small business owners are..

I still chat with piston customers all the time, even months and months after they bought my parts.

"sorry for the longest post ever haha" Just wanted to mention all that.. lol..


also, I wouldnt be upset with anyone here for buying a piston from another business,lol.. I would rather you be happy, no matter where you get them..

At that FPS you will be more than satisfied. It lasts century on that FPS.

haha! I agree.. The rifle will fall apart before these trigger boxes give out.. I have been holding and admiring them all day today so far!

the sears are a nice hard steel, and thats one of the best parts I liked about them.. I also like that the body is aluminum plate, with steel inside! I kept breaking standard trigger boxes.. These, I would say are Ranger proof lol..
And that sear has been used at 860fps with 2000rnds of sgm's
I've got four spare sears but i wont need to replace any time soon if atall. And their not expensive i've bought three s-triggers with two more to purchase :)
Well today my S-trigger arrived and I have installed them now. My first impression was quite ok. There are some things that need to be improved.
Compared to M-Trigger V1 the S-Trigger looks unprofessional made -> all hand made so I think replacement parts will be difficult (all parts are not the same -> need modification or whole box need to be sent to slovakia.
One major thing is that the bottom side of the box is not round up to perfect fit to the receiver. M-trigger solve this by placing the 3 pieces of the shell (sandwich) in a triangle form -> innerpart plate is positioned litte bit inside so that both outershell is sticking out. In that case you have 2 points that stabilize the box instead of one point.
I hope you unterstood what I mean.

The trigger pull of the S-Trigger is ligther than the M-Trigger V1 / V2.

Is it worth the money? I think yes unless you already have a M-Trigger

Dont get me wrong: I just want to give you some feedback where you can improve your product.
I would have to agree about the squareness of the mount plate for the trigger unit. It should be more rounded for a more snug and stronger connection of the unit with the receiver.. I didnt think they really look unprofessionaly made though. I am an "Authorized dealer" of the S Triggers in the United States now also. I will be getting a milling attachment delivered next week to me. I will try to get some milling bits and round the flat part of the units to match the shape of the receivers. It will leave the main parts of the trigger unit thinner so I will only try and round them some. Being that the inside of the "sandwich" is steel, it should still be nice and strong, and way way stronger than the BS aluminum stock trigger units.


I will work out the details with Springer more about having replacement parts on hand like springs etc.. So if anything happens, I can help to fix them so nobody has to ship out of country for help or parts etc..

I will gladly help in any way I can.

Hi, thank you for critics. So let me tell you something too.

"Unprofessional made (hand made)"

Every part is cut by Laser (basic shape) and than it is tuned by hand.
So spare parts are no problem , they will be always the same on 0,05mm. I am assembling 20 triggers at once, so I am picking random parts for assembly (nothing like this piston sear was made to fit this ALU housing)

They looks hand made because I spent a lot of time of tuning them to have great function and minimal friction. I take care to these parts which are functional. I dont polish all parts to looks amazing. I focus on function parts. Trigger is not so expensive for that reason. I dont want to spend so much time on one trigger only for shiny look.

"Bottom side of the box is not round up"

None of the triggers on market have this ,,round up,, except standard cast trigger box. I dont telling it is bad feature but I think on Noobies M-Trig it has mainly psychological effect. When it is perfectly rounded to fit receiver it works but in this case I dont think so. If it was helpful PDI will have it on trigger (probably).

"The trigger pull"

This is most important thing on trigger (with bolt pull) for me (and for function). Which you telling is better than M-trig. So in trigger pull it is desc Zero-trigger, S-trigger, M-trigger, V-trigger and others :)
Thank you for confirming that.

I will make some tests (on your suggestions of design improvements)

I hope you will be satisfied with function of trigger :)
And thanks for feedback

My initial thoughts....

Being the owner of ASPUK we already reatail our own "EZ Trggers" however they have similar trigger pull to the stock trigger. We built ours for reliability and sturdyness. Medium Trigger pull is acceptable.

Springer has sent me a sample as i'm looking to add an alternative option with similar light trigger pull characteristics as the Laylax Zero Trigger.

I am yet to fit the sample to a rifle to test however my initial thoughts are:

Tip of piston sear is quite thin, would this wear down quickly? Could the tip be made slightly thinker to add longevity to the sears life?

Crudely made? Yes, a little. The S-Trigger doesn't have the refined edges of some other triggers out there however I can see beyond this as i'm after something that is going to be very robust.

I noticed the top edge of the trigger is flat. Not rounded to fit the shape of the receiver. Our EZ Triggers don't have this nor do Laylax so i don't think this is an issue.

Trigger pull: TBC, however from my experience it seems very light, prob just a tad off the Laylax Zero Trigger. I've never tested an M-Trig so cannot compare.

I'll respond further once i've tested the trigger.

Alright I trow the S-Trigger out my VSR10 cause I don`t trust the springguide stopper. I have the feeling that the bolt pull is little bit harder.
Here are some pictures that compares the S and M-trigger

I don`t understand why you redesigned the springguide stopper. Your first edition are little bit similar to the M-trigger -> tiny hole and without big groove.
I am using a Polarstar springguide and I am scared that the springguide will have a bad position/bad angle that cause more friction inside the cylinder which lead my tefloncylinder will die very soon.
Are there any advantage if the springguide is extended like the M-trigger?
Can someone confirm my doubt?

Btw: on the second picture you can see that the innerpart is slightly shifted inside to fit better to the receiver

Piston sear in this configuration will last very long time (years), as you can see few post above (53k+ shoots and piston sear does not show any noticeable wear. I goes trough many versions of piston sear (thicker) and this is the best version.
