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
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.

I also just got my trigger today and OH MY GOSH is this thing amazing compared to the 45 degree system.

I have it paired up with a Polarstar 90 degree and spring guide and it works perfectly. With a laylax 170 spring i can cock the gun easily with one finger and once the piston is locked back you literally have to point the gun down and the cylinder slides back forward with next to no resistance. The trigger pull is stronger but the break is very clean and alot nicer than my old TM trigger and is just as nice or in my opinion nicer than the pdi trigger ive used before.

Overall I am so pleased with my purchase and would recomend this to anyone who wants to move to the 90 degree system

I am glad to hear that you like my trigger guys. And thank you for review Dead Ace Shot.

You can order one directly from Polarstar. Just send their CS an email and they'll invoice you.

Nope they told me they stopped producing vsr-10 parts for now,
Because of the HPA.
Yeah I was told they will continue the VSR-10 range after the Fusion Engine range. (Sorry for thread derail).
Well, then you have the option of turning it into a 90 degree piston, if you have the right tools. In fact, I believe that the piston end is loctite-d on, threaded too. You might be able to remove it, convert it, and then loctite it back on.

Idk. Sucks mayn. But, there's a lot of other great 90 degree pistons out there, with cup seals too. Anywho, dragging off topic.

Hi, yes trigger housing is from aluminum. Don't worry, it is strong enough for highest upgrades.
I have a VSR which I bought used and it has an S Trigger.I have to say,the smoothness is unbeatable.Design is simple and effective,it's insanely reliable.Build quality is almost on Par with LayLax and PDI.Defiantly would recommend,cheapest and one of the most reliable trigger systems available for the VSR 10.

New version of S-trigger is ready. 5th revision of trigger brings mainly new design of spring guide stopper , which is shorter and differently shaped. It improved consistency of power needed to pull bolt back.

I also used shorter screws , which no longer exceed end of brass nut.
And few minor modifications.

Aw... Could have used the shorter screws when I ordered it a month ago! Lol.

I think there are more important things on trigger than screws :yup:
I just ordered one of these this morning, can't wait to get it in! Ill be putting it in my m28 with one of rangers pistons. Complete asf sniper build haha :shot:
So I was sent the S Trigger so I can mod it to fit the M28 better.. The Trigger box and trigger guard do not match up as is, and need some work to make match up..

I have inspected the S Trigger and all I can say is wow! This trigger box is seriously a solid piece of work! I can not see this unit to EVER break! I am thoroughly impressed!

If your looking for a serious upgrade, look no further!
I second ranger's opinion. After all, it's my s-trigger in his hands! =D

But yes, as he stated, it will need some modification to work properly with the m28.

In addition to what ranger mentioned, the screw holes need to be bored out to a larger size in order to accommodate for the larger set screws that the m28 uses. Took me about two minutes on a drill press.
I will be happy if you guys post here some pictures and write something more about modifications needed to fit M28. So everyone could decide if it can modify by yourself or not.
