  • Improves air seal and efficiency
  • CNC aluminium Ergal construction
  • Double O-ring and ball bearing set

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 6 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.

  • CNC Machined POM construction
  • Designed for high rate of fire and DSG builds
  • Compatible with all standard AEG Gearboxes

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!

  • CNC Aluminium construction
  • For high performance and DMR builds
  • Compatible with all standard AEG gearboxes

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!

About Our Airsoft Piston Heads

Take your AEG to the next level with a fresh airsoft piston head. Lightweight and built for longevity, our high-quality piston heads only ever come from the best named brands on the market, such as ASG and Modify. 

###pairsoft piston and is the part that actually compresses the air inside the cylinder. It requires a good seal between the cylinder and edge of the piston head, but still needs to be able to move freely. 

Some piston heads allow air in the front of them to 'inflate' the o-ring as it travels forward. This helps improve compression and air seal, without constantly pressing on the side of the cylinder. Some are mounted on bearings to assist with free movement and prevent snagging inside the cylinder.

If you’d like more information before you decide which piston head is right for you, feel free to get in touch with one of our technical experts!
