- Upgrade spring
- Fits most Airsoft AEGs
- Different strengths available
Springs are the perfect upgrade for an instant FPS boost! They fit in most standard AEGs and have a relatively simple installation process. Many rifles these days have some sort of quick-change spring system which makes your life even easier when upgrading your rifles.
The Bolster Armouries Premium AEG Spring is the best of the best when it comes to internal springs. These are the same springs used in our Bolster Armouries rifles, that's just how premium these springs are! If you want your rifle shooting like a Bolster Armouries ONYX, then the Bolster Armouries Premium AEG Spring is certainly a step in the right direction!

- Rubber construction
- Replaces the HOP-up unit spring
- Provides superb air seal
If you're the techy type and want to maximise your AEG's efficiency, the Bolster Armouries HOP-up to Barrel O-Ring Shim Set belongs in your toolbox! This set includes 10 o-rings designed to fit around the HOP-up unit and inner barrel, forcing it back to meet the gearbox as seamlessly as possible to promote maximum efficiency and reduce shot-to-shot FPS deviation.
This set is designed to replace the "one size fits all" HOP-up unit spring, providing a user-customisable solution to account for manufacturing tolerances. While this will take a bit of trial and error to get the perfect fit for your AEG it should prevent airseal qualities from reducing over time and avoid that annoying realisation that you forgot to reinstall the HOP-up spring after upgrading or maintenance!
The Bolster Armouries HOP-up to Barrel O-Ring Shim set should fit almost every AEG on the market and you probably won't need to use the full set, meaning you might even be able to replace two HOP-up springs with a single set.
- Rotary adjustment wheel
- High-density polymer HOP-Up chamber
- Designed for M4/AR-15 AEGs with V2 gearboxes
If you are having HOP-up troubles with your M4 platforms, don't worry, G&G has just the thing for you! This HOP-up chamber is a replacement part and comes with the necessary pieces for installation, but does not include a HOP-up rubber or a nub. The main chamber is made from high-density polymer and is compatible with all M4-style AEGs which have V2 Gearboxes. It's a reliable and high-quality replacement part that will help your AEG shoot like brand new again!
The rotary adjustment dial is the latest and greatest way of setting your rifle's HOP. It is much more accurate and provides finer increments of adjustments when compared to previous gear-style HOP-up adjustments.
- Optical MOSFET
- Gate Quantum trigger included
- Pre-installed Expert Firmware
If you're running an SMG-5, M4/AR-15 or any other AEG which uses a version 2 gearbox, the GATE ASTER™ MOSFET will take your AEG to the next level. This advanced electronic trigger unit replaces your conventional trigger contacts with optical sensors, allowing for 250 different trigger sensitivity settings, burst and binary fire modes and a plethora of other functions to be programmed in using either the trigger and fire selector or the Gate Control Station App.
This set also includes the Gate QUANTUM CNC trigger which is compatible with M4/AR-15 AEGs but unfortunately won't work with SMG-5 or G3 platforms. When installed, the Quantum trigger offers 250 trigger sensitivity options via the ASTER's optical sensors. Constructed from CNC-machined aluminium, the Quantum both looks great and allows the ASTER™ to take full advantage of its optical trigger sensors.
This MOSFET is a great choice due to its fantastic balance of cost-effectiveness and performance, offering incredible efficiency improvements even before you get into the programmable features and customisation options. As with all ETU/MOSFET systems, a certain amount of expertise will be required to install the ASTER™ so if you're not confident, we suggest seeking a technician to carry out the installation process for you. If you're ready to take your AEG's performance to the next level, you're ready for the ASTER™
- High Torque motor
- Perfect replacement part
- Long shaft - For M4, G3, SMG-5 & P90 AEGs
If you've had motor issues and need a cheap replacement, here you go! The CYMA Standard Motor Long Shaft is a standard-speed long shaft motor for M4/AR-15, SMG-5 (not K), G3 and P90 AEGs. It is the perfect part if you're noticing some performance issues with your platform and the power is underwhelming. The set includes a pre-installed D-type pinion gear and pinion spring, both of which are pre-installed on the shaft.
- Semi Only MOSFET/ETU
- Adjustable pre-cocking
- Compatible with M4/AR-15 AEG with V2 gearbox
If you are looking for an easy way to make your Airsoft platform exclusively a DMR or CQB beast, this is worth checking out! The Delta Armory Programmable ETU Processor Unit for V2 Gearbox; Semi Only replaces your conventional trigger assembly and offers semi-automatic fire only with adjustable pre-cocking, which can be programmed in using the fire controls of the AEG itself.
This ETU should fit most M4/AR-15s which use a version 2 gearbox, but we only recommend this part for experienced techs and those in the know when it comes to Airsoft internal upgrades. The ETU is also pre-wired to a Deans/T-Plug battery connector in rear wired configuration and spade connectors for your motor, so you shouldn't need your soldering iron!
- Pre-wired MOSFET & ETU
- Provides programmable fire modes
- For version 2 gearboxes
If you need a replacement for your G&G MOSFET or want the latest version with its more compact design, the G&G Armament ETU/MOSFET for G2 Gearbox; Rear Wired is ideal. This set is pre-wired for relatively easy installation and is the latest G&G MOSFET 4.0 with its more compact form, saving you space in your battery compartment.
Installing this set gives your AEG the option of programming 3-round burst instead of full auto, great for those who keep running out of ammo due to a heavy trigger finger! Other features include low-voltage cutoff and cycle completion, ensuring both your gearbox and battery are kept healthy in the long term. Worth noting is that this set will require 11.1V LiPos to be used and if you're installing this in a non-G&G G2 AEG you will need to carry out modifications to ensure your setup does not pre-engage (AOE correction at the least).
