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.

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!

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 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™!

If you're searching for an advanced MOSFET for your version 3 gearbox-equipped AEG, the ASTER II Bluetooth® MOSFET for Version 3 Gearbox from Gate Electronics is ideal. 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 in 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.

The ASTER II is compatible with any version 3 gearbox-equipped AEG and can also be used with the Gate PULSAR Single or Dual-Solenoid HPA Engines if you add the ASTER II-specific HPA cable for the appropriate engine type. If you're ready to turn your Airsoft gun into a Space Gun, the Gate ASTER II Bluetooth® MOSFET for Version 3 Gearbox is calling your name!

Turn your AEG into a TITAN with Gate's new flagship electric trigger unit (ETU), the TITAN II Bluetooth for Rear Wired V2 Gearbox with Basic Firmware.

Built-in Bluetooth 5.2 technology gives you direct access to the TITAN's settings on the fly, using AEG telemetry to allow you to use your smartwatch, STATUS and other future devices in the Gate ecosystem of devices.

The innovative gear sensor not only counts each tooth but also as the first in the world determines the direction of a gear's rotation, offering you the most precise of cycle controls in AEGs.

With mind-blowing optical trigger sensor, the TITAN II allows you  to set your hair trigger with ludicrous precision, with a whopping 50 sensitivity levels for the first millimetre of trigger movement.

The TITAN II is equipped with a multifunctional port ready for connecting additional accessories such as bolt-catch, magazine sensor, tracer in hop-up chamber and others.
