3rd generation of the successful trigger mechanism for rifles VSR system. List of improvements can be found below.

Durable and reliable trigger mechanism is basic premise for a successful upgrade sniper rifle. Stock supplied trigger mechanism is sufficient for basic springs. But when you use stronger springs, significantly increases possibility of the damage. Unfortunately you can`t avoid this even with cheap alloy triggers. Only steel machined mechanism can ensure the greatest durability.

Rifles working on a system Marui VSR have very bad piston catch system. It is capturing only a small edge and angle of 45 degrees. This is sufficient for relatively basic weak spring, but can`t hold stronger springs. In addition, 45 degree system lift piston end and cause jam in the cylinder.

Our CNC metal trigger mechanism brings different solution. It holds piston at 90 degrees (Some customers call it Zero Trigger). Surface is larger and can hold stronge springs. This solution require piston replace. Therefore, it is in the package. And not only trigger and piston, but also steel spring guide and spring based on your choice.

We also developed own technical solutions and components. For example, construction of the trigger, bearing, location of springs, etc..


Body made by CNC machining from light, but durable aluminum alloy 6061-T6.
Aluminum 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 equiped with ball bearing for the smoother trigger press.
Axis are made of stainless steel.
Two torsional springs safety returns catch to the original position.
Whole trigger is made of 27 parts.
Tested on springs up to M180.
All spare parts available.
Easy to install under five minutes. Link to the video installation guide in HD resolution on each packing.
Complete set is designed and manufactured in the Czech Republic. Partial technical solutions are protected by copyright!
Package include trigger set, spring guide, spring and hybrid piston.

Version 2 improvements:
The piston has a lightweight design and result to weight loss
The piston has a plastic guide rings with a smoother surface for better sliding in the cylinder
Spring steel wires has a smoother outer surface and is additionally nickel coated
Brass base is now fixed with only one screw
Piston sear was extended by 0.6 mm
The trigger has revised the structure and has less wooble
The mechanism allows the use of a new fuse. This applies from the original trigger
mechanism. (Tested on brand Well only! Other models may require some modifications.)

Version 3 improvements:
Brand new steel spring guide, which allows to use standard 7mm springs. And once you put 9mm rotation sleeve on it, then you can use upgrade 9mm springs. (means inner spring diameter)
Outer rotation spring guide sleeve is equiped with the thrust axial bearing. It makes bull back much smoother, because allows limited spring rotation.
Set is equiped with the brand new VDSiCr springs in a range M150 - M180. Springs are marked "S" and are little bit shorter compare to our common 9mm springs. It is due to ball bearing on the spring guide. Long standard springs would not fit inside piston.

New body construction makes assembly much faster and do not require trigger guard modification !
Modern packing in a PVC box for better protection.
This high quality trigger set is dedicated for Marui VSR-10, JG BAR-10, Well MB02, MB03, MB07, MB09, MB10, MB11.

Not fit on M24, Marui AWS, Well MA4401,4402 or Well L96.

If you select most popular M150 spring, final velocity of the gun will be around 160-165 m/s (530-550 FPS). We really suggest to use this spring, because it has the best FPS performance and is not so hard for pull back.

Update 8.6.2016. Piston sear has been modified. Problem with the hard trigger has been
