Laylax PSS10 VSR Zero Trigger w/ Piston Set

Code: 12160
  • 90 Degree Catch
  • Strong & Reliable Unit
  • Incredibly Smooth Release

The must have trigger unit and piston combination for any Airsoft sniper using a VSR/Bar-10 compatible platform. A 90 degree setup results in unreal strength for some incredibly strong spring choices.

Full description


The trigger release is also unlike any other build. The whole unit is built to last, very rarely do you need to service this unit, but with it being quite open you can easily get to all moving parts to add a little oil now and then and remove any build of up debris. The piston can also be broken down into 4 parts for a proper deep clean. The piston head also has a reasonably thick sorbothane pad to absorb some sound and impact. The white tip you see in the photos is an air brake system. This makes your rifle even quieter but can reduce the FPS of your gun. If you do not want to have the air break, it can be removed by hand and replaced with the included grub screw.


  • Removable air break damper rod (makes your rifle quieter if used but reduces FPS)
  • Piston pick-up end and Teflon rings are removable for servicing
  • Very lightweight
  • Incredibly durable
  • 6 hole ventilation piston head
  • Sorbothane padded head
  • Takes up to 13mm wide springs
  • Improve your FPS and consistency
  • 90 degree catch for extreme durability and trigger release
  • Single stage trigger
  • None-adjustable trigger pull, due to its precision pre-setup

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.

If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
