  • 90 Degree Sear
  • Amazing Value Set
  • CNC With Anodised Finish

This 90 degree trigger and piston set is a must have combination for any Airsoft sniper using a Tokyo Marui based or clone VSR / Bar-10 bolt action sniper compatible platform.

Full description


A 90 degree setup results in unreal strength for some incredibly strong spring choices. 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, as it is a close box unit dust and debris is unlikely to find its way in. The piston can also be broken down for a proper deep clean. The piston head also has a reasonably thick sorbathene pad to absorb some sound and impact. This trigger set is amazing for the value and would be an amazing addition to any compatible sniper set up offering a very positive locking sear and great trigger pull

      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.
