The outer structure of this trigger box is freely based on the mechanism of PDI, but the internal structure is closer to the original Well mechanism. AirsoftPro also developed their own technical solutions and components. For example, construction of the trigger, bearing, location of springs, etc. This decision is purely practical, because it is the basic and most stressed three parts (piston catch, lever and the spring guide stopper) used for the original trigger mechanism manufacturer Well. Below you can find basic facts:

• Body made by CNC machining from light, but durable aluminium alloy 6061-T6.
• Aluminium parts with high quality anodized finish.
• Piston catch, lever and the spring guide stopper are made of steel and hardened to HRC48-55.
• The top of the trigger is equipped with ball bearing for the smoother trigger press.
• Axis are made of stainless steel.
• Two torsional springs safety returns the catch to the original position.
• Whole trigger is made of 26 parts.
• Tested on springs up to M190.
• Inner parts can be used in original Well triggers.
• Easy to install under two minutes.
• Allow to use stock safety lever - new in GEN.2

This high quality trigger set is dedicated for Well MB01, MB04, MB05, MB08, MB14..etc with the classic 90 degree piston catch. You can use it for stock Well or any custom upgrade pistons and cylinders.

This trigger won't fit on guns with 45° piston catch like MB02, MB03, MB06, MB07, MB10, Bar10, VSR10, series MA44xx..etc. Not suitable for M24.

These generally require a level of technical skill to fit properly so we do advise you have it fitted by a competent technician.
