Airsoft Piston Heads

If you're working on your gearbox and looking for more efficiency, the Lonex Aluminium Piston Head for V2/V3 Gearbox is ideal for your build. This piston head is constructed from CNC aluminium and is equipped with a rubber O-ring surrounding its surface to close the gap between the piston head and cylinder, ensuring every bit of air compressed by the piston is translated into downrange effect.

This piston head is compatible with version 2 and version 3 AEG gearboxes and is a handy part to have around for the techy types. Whether you're building a custom gearbox or upgrading, the Lonex Aluminium Piston Head for V2/V3 Gearbox is an essential part!

If you are looking for a replacement piston on the cheap with no performance compromises, CYMA to the rescue! The CYMA Steel Tooth Piston Set w/Piston Head includes the piston itself, a piston head and a piston head O-ring. The piston has a full 15-tooth rack of steel teeth, improving strength while keeping overall weight manageable, making it great for high performance builds. The set is designed for version 2 and version 3 gearboxes and will be provided in a random colour; either blue or green.

Upgrade your AEGs piston head to improve air seal and increase the efficiency of airflow through the cylinder. This piston from FPS Softair has ports on the front to push out the O-ring as it moves forwards, this ensures that all of the air in the cylinder is being pushed out to propel the BB.

Constructed from CNC aluminium Ergal, which has been anodised, the piston head features a smooth precise surface. The piston head has ports on the front to push out the O-ring as it moves forwards, this ensures that all of the air in the cylinder is being pushed out to propel the BB.

The ball bearings help reduce tension created by the spring compressing and expanding, this combined with a ball bearing spring guide is the optimal set up to keep your spring in good shape.

This is the most advanced version with 8 ventilation holes for higher speed and rate of fire, double O-ring and ball-bearing. This head is designed for version 2 and 3 gearboxes but may fit other types.

If you have stripped your piston and need a replacement, here ya go! The KRYTAC Piston & Piston Head Assembly V2 for M4/AR-15 AEG is a replacement original parts set including a polymer piston with a 4-tooth steel rack and a polymer piston head with pre-installed O-ring. The set is designed for the Krytac Trident AEG series but is compatible with M4/AR-15 AEGs equipped with a version 2 gearbox.

If you're building a high ROF AEG this piston head could be the part you have been waiting for to squeeze that bit of extra speed from your AEG. The Gate High Speed CNC POM Piston head is designed for standard AEG gearboxes, including versions 2, 3, 6 and 7, but is not compatible with non-standard gearbox setups such as the TM NGRS rifles or the BOLT BRSS series. Gate designed this piston head with high rate of fire builds and dual sector gear builds in mind, and its ultra-light POM construction lends itself well to this role. Using POM polymer may lead some to think this piston head lacks strength, but it is rated to handle springs of up to M140; more than enough or anything UK legal!

If you are building up a DMR AEG you will want one of these inside! The Power CNC Aluminium Hybrid Piston head from Gate combines innovations from the AEG piston head market with those from Sniper rifles to allow the weight of the piston head to be adjusted to help reduce power loss when using heavy BBs (>0.3g). With the Hybrid Piston Head you have the choice; either install the piston head alone for improved air seal, longevity and reduced friction, or if you're building a DMR you can add the included weight pads to increase the weight of the piston, and reduce lost FPS when using BBs weighing over 0.3g. Perfect for a DMR build, but equally great in a standard AEG build, Gate has really broken the mould with this one!
