- High-density polymer
- Rotary adjuster
- For LCT LCK/AK AEGs
If you need better accuracy from your LCT AK AEG, this should do it! The LCT Rotary Hop Unit for AK AEG is designed for LCT AK replicas (LCK range) but may fit other brands, though we cannot guarantee off-brand compatibility currently.
This new HOP-up design brings the rotary adjuster style to the AK platform, offering reduced side-to-side shot deviation, improved setting retention, and finer adjustment increments. Like the original slider unit, this rotary accepts standard TM AEG spec HOP-up buckings, nubs and inner barrels.
- Teeny Tiny size
- Compatible with most AEGs
- Protects trigger contacts and improves ROF
This is the smallest Airsoft MOSFET on the market! It grants you a better rate of fire and trigger response, as well as protecting the mechanical trigger contacts in your AEG, as electrical currents bypass them and go straight to the motor. The MOSFET is so compact that it can be fitted to pretty much any Airsoft AEG.
It attaches to the wiring of your gun and will require some expert knowledge and skills to fit. Make sure you know what you're doing before installation! Also included in the package is a heat shrink, so you can keep this MOSFET safe after you have installed it.
- Progressive Coiling
- Coloured Rating Tip
- SiCr Zinc Coated Steel
Produced to an incredibly high quality with the best mil-spec steel rated SiCr. Every spring no matter the rating has gone through a full quality control test by ASG for your peace of mind that you are fitting a reliable spring.
- Soft Bucking
- Grippy Material
- Air-Tight Design
A soft Hop Rubber for Marui compatible AEGs offering an air-tight design, which comes supplied with a nub and is a purple colour.
- CNC Aluminium & POM construction
- Various O-rings included
- Rotary style adjuster - M4/AR15 AEG & HPA compatible
If you are building out your M4/AR15 AEG for maximum performance the Gate EON HOP-up unit is probably already on your list! This precise HOP-up unit is constructed from CNC machined aluminium and is a rotary style unit which applies pressure directly to the top of the HOP-up rubber/nub to minimise side-to-side deviation.
This unit is compatible with M4/AR15 AEGs and can also be used with HPA setups thanks to the included nozzle sleeve which perfectly centres the nozzle for maximum efficiency.

- Complete V2 Gearbox
- Fits most M4/AR-15 AEGs
- SHS Piston & reinforced tappet plate
If your M4 needs a revamp, a new gearbox is the easiest way to do it. The Delta Armory Complete Version 2 Gearbox for M4/AR-15 AEG is compatible with almost every M4/AR-15 AEG on the market and is well-equipped with reinforced parts straight out of the gate.
This is the same gearbox used in the Delta Armory CHARLIE™ line AEGs, boasting a quick change spring guide, 18:1 steel gears running on 8mm bushings, an SHS piston with a full steel tooth rack, an SHS reinforced tappet plate and a reinforced gearbox shell with radiused cylinder window corners.
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!

- 6.02mm Precision barrel
- Stainless steel construction
- AEG Barrel cut - Fits most Airsoft AEGs
If you want to improve your AEGs accuracy, range and consistency, a barrel upgrade is a great start! The Specna Arms 6.02mm Steel Tightbore Inner Barrel promises to be an improvement even over stock 6.03mm brass tightbore barrels and its stainless steel construction makes it far more rigid and less prone to bends than other brass and aluminium barrels.
This barrel is cut for standard Airsoft AEGs and should fit most of them, though we suggest referring to the product description of your gun to find out what length you need. The standard AEG barrel cuts mean you can use this precision barrel with standard AEG HOP-up buckings, HOP-up nubs and HOP-up units, meaning all your existing parts should fit and plenty of opportunities to pair this barrel with other accuracy upgrades. If accuracy is a priority for you this upgraded barrel is a must!

- R-HOP Kit - Great for heavy BBs
- Includes bucking, HOP arm & nub
- Ideal for AEG DMR builds
If you're building a DMR or accurised AEG, the Delta Armory BERSERKER R-Hop Bucking Bundle for AEG is what you need to achieve maximum range. This set includes an enhanced HOP-up arm, HOP-up bucking and OMEGA-style nub manufactured for Delta by upgrade legends Psionic Upgrades. The included HOP-up arm is designed for M4/AR-15 AEG rotary HOP-up units, specifically the Delta Armory/Specna Arms/Evolution/Lancer Tactical type but the bucking and nub are compatible with other Airsoft AEGs of all different shapes and sizes.
The inner patch of the BERSERKER bucking is shaped to fill the HOP-up window on your barrel, just like home-brewed R-HOP setups of old. The advantage of using a BERSERKER set rather than doing all the mods yourself is its simple drop-in installation, low price compared to sourcing a separate bucking, nub and HOP-up arm and guaranteed compatibility, meaning no chance your nub doesn't work with your chosen bucking. If you use heavy BBs and need a range increase, this set will do exactly that!
- CNC 7075 Aluminium construction
- For M4/AR15 AEG with Gate ASTER V2
- Adjustable trigger sensitivity - 470 sensitivity levels
If you are building yourself a tech-filled, Gate ASTER V2 equipped M4 AEG then an interesting trigger is a great way to add some discrete external flair to your custom build to give onlookers a slight hint at what's inside. The Quantum Trigger from Gate is interesting in many more ways than one!
The Quantum trigger is available in 4 different shapes, all of which are CNC machined from aluminium, giving them a flawless appearance and a strong, flex-free structure. The colour options are almost endless, giving you the choice of some eye-catching metallics or dull and discrete tactical colours to suit any build, from DMR to speedsoft BB hose. The Quantum trigger becomes all the more impressive in its functional qualities; pairing it with the Gate ASTER V2 allows the trigger sensitivity to be adjusted to 470 different settings with over 60 settings just for the first millimetre of movement. Our jaw is still hanging open!
