- Made in England
- 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.
- ETU & Trigger set
- For V3 Gearbox (AKs only)
- Programmable fire modes & pre-cocking
If you need a cheap ETU to give your AK advanced features, the Specna Arms HAL™ ETU for V3 Gearbox is a fine choice. A pre-wired Electronic Trigger Unit (ETU) equipped with a Deans battery connector, the HAL™ is designed to fit version 3 gearboxes, and the included trigger is designed for AK AEGs. Due to the magnetic trigger sensor, the included trigger must be used for the HAL to work. As such, this is only compatible with AK AEGs.
With the HAL™ installed, you can access programmable fire modes, including 3 or 5-round burst, binary trigger, semi-auto only, sniper delay and AUG mode (two-stage trigger). The HAL™ also allows you to set pre-cocking to one of 5 levels, letting you crank up trigger response to near-instantaneous. All programming instructions are carried out using the trigger and fire selector, and instructions can be found on the Specna Arms website. The HAL™ requires expertise to install, so if you're unsure, we recommend consulting a technician.
- Bluetooth connectivity built in
- Expert firmware preinstalled
- Fits V3 GB AEGs & single-solenoid HPA engines
If you're revamping a version 3 gearbox-equipped AEG, the GATE ASTER II Bluetooth® EXPERT for AEG & HPA Version 3 Gearbox belongs inside! A cutting-edge advancement over the original Gate ASTER MOSFET, the ASTER II boasts several quality-of-life improvements, more customisation options than ever before and Bluetooth 5.2 connectivity built in, allowing you to change settings wirelessly on your smartphone or mobile device.
The ASTER II 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 using either the trigger and fire selector or the Gate Control Station App.
Other programmable options include adjustable pre-cocking and adjustable active braking; perfect for the techy types to set their primary up to suit practically any build objective, from high FPS DMR to a beastly high-speed DSG.
The ASTER II is compatible with any version 3 gearbox-equipped AEG and can also be used with HPA engines when paired with the aftermarket HPA Cable Set for the engine type (dual or single-solenoid). If you're ready to take your AEG to the next level of advanced functionality, the GATE ASTER II Bluetooth® EXPERT for AEG & HPA Version 3 Gearbox is waiting!
- CNC 6061 Aluminium
- For standard-length AK rifles
- Requires a Z-style handguard
If you're styling up your AK build with optics mounting as an objective, the LCT 20mm Picatinny Railed Top Cover "Classic" for Z Handguard is a solid choice. Made from CNC-machined 6061 aluminium with robust steel bolts, this receiver top cover/dust cover is designed for standard-length AK AEG platforms (not AKS-74U or PP-19) but must be paired with an LCT Z-style handguard to be mounted correctly.
This top cover is a hinged design, making battery access a breeze for top-wired AK AEGs. Its upper 20mm Picatinny rail runs the full length of the top cover, providing plenty of space for optics and a reliable zero. Compatibility-wise, this part is designed for LCT AKs; while most AK AEGs are cross-compatible, we cannot guarantee off-brand compatibility.
