icon Description

Upgrade set for Tokyo Marui AWS airsoft sniper rifles and Chinese copies such as Well MB44xx. Include piston, spring, and spring guide.

Piston body is made on the CNC machines with the blue surface, piston head has rubber pad o-ring.

Spring guide is made from one steel block,CNC machined and zinc coated.

Spring is specially designed for this set. It is smaller compare to other sniper rifles spring, because it must fit in a small space. Due to 45 degree trigger system we cant offer very strong spring. Catch could not hold it. So set include spring equal to M140 – M150.

Set is dedicated for Marui AWS and Well copies MB44xx series (for example 4401,4402,4403,4404, 4410, 4411,4412…etc),

but you have to use the Airsoft PRo CNC trigger mechanism. You can buy it here.

Set is not suitable for VSR, MB02,03, M24, MB01..etc.
