Airsoft Cylinder Group & Compression Parts

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.

FPS Softair brings you a super high quality M4 piston with a technopolymer body and a full rack of steel teeth for a good combination of high strength and low weight. This is compatible with Tokyo Marui NGRS M4 gearboxes, aka the Version 9 gearbox. Please note, this piston is not compatible with the TM NGRS SCAR-L or SCAR-H.

The loaded technopolymer assures great mechanical resistance and dimensional precision. The rack was manufactured through the use of MIM (Metal Injection Moulding) technology since this production process guarantees dimensional accuracy and sturdiness equal to those of solid machining.

Currently considered the best for this type of use, the metal injected is SAE 4650 steel. The sliding guides are designed to minimize friction and hold the lubricant for a long period of time, so you can be safe in the knowledge that your AEG will have reliable and long-lasting cycle functionality.

If you're looking for a strong and lightweight nozzle for your P90, check this out! The FPS Softair CNC POM Nozzle with O-ring for P90 AEGs is made from CNC POM polymer, a massive upgrade from the factory polymer nozzles present in TM P90s and clones. The nozzle also includes an internal O-ring to maximise air seal and its ultra-strong POM construction is ideal for high rate of fire or high FPS setups.

FPS Softair is a fantastic company, offering high quality upgrades for unbeatable prices, all designed and manufactured in Italy. The techs at FPS recommend lubricating the nozzle step of your piston head before installation using silicone lubricant. If you're working on a beast of a P90 build and want it ready for anything, the FPS CNC POM Nozzle with O-ring for P90 AEGs is what you need!

FPS Softair brings you a high-quality piston with a carbon fibre-reinforced technopolymer body and a full rack of steel teeth for a good combination of high strength and low weight. This is compatible with Tokyo Marui-style Version 2 and Version 3 gearboxes.

This Superlight piston reduces friction for an increased rate of fire, in addition to the overall reliability of your rifle. The sliding guides are designed to minimize friction and retain the lubricant for a long period of time and the rack seat is decentralized to favour the coupling between the piston teeth and those of the sector gear.

Upgrade your Lee Enfield with a superior cylinder. Tough and durable, the cylinder is specifically for the Lee Enfield S.M.L.E No. 1 MK III, with the cylinder set constructed from stainless steel and Teflon coated, to reduce piston friction. As a result the set can work with high-power springs.

If you are tuning your gearbox for a high rate of fire build a reinforced tappet plate is a must for your shopping list. The Perfect Tappet Plate from Laylax replaces your original tappet plate to keep your AEG running for longer at high speed thanks to its reinforced polymer construction.

Can be fitted inside other rifles including AEG gearboxes. The sorbo pad works by absorbing impact from your piston head, please note you should expect an FPS loss so you may have to improve the air seal or fit a slightly larger spring to regain your desired FPS.

If you're running an M4 AEG and seeking a cylinder head upgrade, the SHS V2 Cylinder Head for M4/AR-15 AEGs is a fantastic affordable option. Equipped with two O-rings around is circumference to close any gaps between your cylinder and the head, this cylinder head is compatible with any version 2 gearbox equipped M4 AEG.

The cylinder head body is constructed from CNC-machined aluminium and features a rubber dampening pad on the rear designed to reduce gearbox noise by cushioning the impacts of your piston head. If you're looking to enhance air seal or build a version 2 gearbox from scratch, the SHS V2 Cylinder Head for M4/AR-15 AEGs will suit you perfectly!

The GATE AOE spacer is an ideal and straightforward upgrade for your Airsoft AEG. Positioned behind the piston head, it helps achieve the optimal angle of engagement (AOE). This refers to the angle at which the first tooth of the piston engages with the sector gear's teeth. Incorrect AOE can lead to excessive wear on the piston guide rails and the first tooth of the piston.

Proper AOE adjustment greatly extends the lifespan of the piston and helps prevent jams, which are often caused by incorrect alignment. It also improves FPS consistency by allowing smoother and more accurate gear engagement during each shot. The spacer is compatible with pistons that have a 5 mm centring hole and piston heads with a 5 mm centring spline.

Upgrade your Airsoft AEG with the GATE AOE spacer to enjoy more reliable performance and extended piston durability through countless skirmishes.

If you are tuning your gearbox for a high rate of fire build a reinforced tappet plate is a must for your shopping list. The Perfect Tappet Plate from Laylax replaces your original tappet plate to keep your Tokyo Marui NGRS AEG running for longer at high speed thanks to its reinforced polymer construction.

Building a beast of a gearbox? The Gate Protector CNC Aluminium Cylinder head guarantees a fantastic air seal thanks to its double o ring configuration. The Protector cylinder head is constructed from CNC machined aluminium and includes two rubber buffers of differing hardness, one of which can be installed on the rear of the cylinder head to reduce the impact force on the front of the gearbox shell and prolong its life. This cylinder head is best suited for standard builds or high performance DMR style builds and has super tight tolerances making fitting a breeze while reducing friction between parts which can result in premature failure.

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!
