The Airtech Studios RetroArms Rotary Centring Unit is an easy upgrade to improve your AEG's accuracy. It is constructed from high-density polymer and fits a RetroArms CNC Rotary HOP-Up Chamber Gen.2 ONLY. It prevents the hop-up unit from wobbling side to side. Once fitted, the RetroArms Rotary HOP-Up Chamber will be securely fitted in place and sit in its true centre position, which prevents BBs from swerving at a tangent when shot.

As well as removing the wobbling from your HOP-up chamber, it also provides a better air seal due to the improved tightness of the system, resulting in a more stable FPS output from your AEG. While the power upgrades for shooting BBs further are significant, they wouldn't be effective without accuracy. It's often that small parts like this are overlooked in Airsoft upgrades but they have a major impact and the Airtech Studios RetroArms Rotary Centring Unit is exactly that.

Improve the consistency and accuracy of your RetroArms CNC Rotary HOP-Up Chamber Gen.2 with a simple polymer part, the improvement will be instantly noticeable!

If you are upgrading your MPX AEG, a ball bearing spring guide is a great way to reduce stress on the gearbox and spring, and prolong the life of your internals when operating in high-strain setups. The Laylax Ball Bearing Spring Guide is designed for the MPX and is a quick and easy replacement thanks to its quick change functionality.

The spring guide is constructed from steel, which alone will prolong its life considerably, but the ball bearings in its base allow the guide to spin freely and redirect any stress on the gearbox shell, and the spring itself.

The Patrol Base Large Tamiya Connector is an essential spare to have if you are the techy type of Airsofter who cannot resist customising their kit, but could also be useful for anyone who participates in RC hobbies. The set includes the connector and the outer plastic shroud, and is available as either a set to mount to your gun (Gun end) or a set to mount to your battery (Battery end).

The Bolster Armouries AOE Correction Washer is the perfect easy upgrade for your Airsoft AEG. It fits behind the piston head and ensures your replica has the perfect angle of engagement. This is the angle at which the first tooth of the piston toothing comes into contact with the toothing of the sector gear. If the AOE is incorrectly adjusted, the piston guiding rails and the first piston tooth are subjected to increased wear.

The correct AOE adjustment significantly increases the lifetime of a piston, it can also reduce the chance of your Airsoft platform jamming, which often occurs when the angle of correction is not correct. The FPS will also be more consistent due to a smoother and more precise engagement when firing the AEG.

Treat your Airsoft AEG to the Bolster Armouries AOE Correction Washer and watch as its performance becomes more consistent and the piston survives many more skirmishes.

IFRIT Motors have a great reputation for speed and response rate, featuring inside G&G's ARP series and SSG-1. If you want improved rate of fire and trigger response, the G&G Armament Long Shaft IFRIT 25K Orange Motor will give you just that!

If you're working on a high-speed or high FPS build, the Delta Armory Version 2 CNC 8mm QSC Gearbox Shell will save you a lot of heartache in the long run! This ultra-strong version 2 gearbox shell is CNC machined from the best aluminium around, known as 7075 T651. This means if you're running a super strong spring or going for a dual-sector gear build, this gearbox shell has what it takes to keep running in the long term, being considerably stronger than standard alloy gearbox shells.

The QSC Gearbox shell also features radiused cylinder window corners to better distribute force and is pre-cut for Gate TITAN/ASTER, Perun Hybrid or Delta Armory ETU MOSFET systems, meaning no need to get the Dremel out to add advanced functionality. The bearing ports are 8mm in diameter, making this the perfect host for Bolster Armouries EZO Ball Bearing Bushings. If you're reaching for the stars when it comes to performance and want your build to last more than a few bursts, the Delta Armory Version 2 CNC 8mm QSC Gearbox Shell is what you need!

The pre-installed spring will provide around 380 FPS when installed, so if you plan to use this gearbox for anything other than a semi-auto-locked DMR build you will need an M100, M105 or weaker spring to keep it within site limits. Thankfully, the quick change spring system makes spring swaps a breeze! Whether you are breathing new life into an old M4 AEG or you are building an AEG from scratch, this complete gearbox will save you loads of time and messing around!

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!

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 is the MOSFET we use in our Bolster Tuned platforms 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™
