Full description


The Trigger Set is constructed from High Quality and Durable Steel, and the Piston is constructed from CNC Machined Aluminium with Polymer Guide Rings, and Rubber O-Rings. The Trigger Box is a One piece Trigger System, which is designed to have an extremely short trigger pull, also know as a zero trigger, for more accurate and immediate shots. Internally the trigger box features Roller Bearings to prevent wear, and Steel Sears to take the stress of high powered Springs for High FPS builds. The Piston is constructed using a CNC Process making it durable and precise, and is ported to reduce its weight. The front of the piston features a rubber o-ring to cushion the impact with the front of the cylinder to reduce noise and wear. The piston also features polymer guide rings to prevent wobble as it moves up and down the cylinder. Your rifle may require slight modifications, such as to the trigger guard, or to the Piston Guide Rings depending on your Rifle / Cylinder Setup. For more help or fitting instructions please see the Special Instructions at the bottom of the page. This upgrade set is perfect for those who are looking to upgrade their VSR / BAR-10 Sniper rifle, or for those who simply like to tinker with their rifle until it is perfect

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.
