Description

ZERO Upgrade Set for Marui AWS and Well MB44xx with M140 spring 7332 [AirsoftPro] 

Durable and light upgrade set for Tokyo Marui AWS and copies, such as WELL MB44xx series. 
 
Hybrid Piston
 
The piston is made by CNC machining from light, but durable aluminum alloy 6061-T6 (Dural) with a high-quality anodized finish.
The piston catch is made of stainless steel.
The piston has one sliding polyacetal (POM) ring.
The piston head has an back-pressure system with O-ring (O-ring expands and seals better when shotting).
The enlarged inner piston diameter allows you (and we recommend) to insert a stronger 9mm spring upgrade.
Dimensions: lenght - 75,9mm, outer diameter - 19,8mm, inner diameter - 13,5mm
Weight: 24g
 
Spring Guide
 
Allows the use of classic 7mm springs and stronger 9mm spring springs.
Axial bearing makes pull back much smoother, because of limited spring rotation.
The spring guide is made of stainless steel with a perfectly smooth surface.
 
M140 Spring
 
High-quality spring made of spring wire with heat treatment and grinded ends.
Chemically blackened against corrosion.
The outer diameter of the spring is about 12.8mm.
 
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 OUR CNC trigger mechanism. See product code 10639. see below
