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!

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.

If you are looking for accuracy and FPS upgrades, a tightbore inner barrel is the easiest way to get a bit more from your current setup without adding strain to the gearbox. With this stainless steel tightbore from ZCI installed, you should see a slight FPS increase due to improved air seal, and better accuracy down range thanks to the tighter bore and precise internal finish.

This inner barrel is compatible with standard AEG HOP-up units and is 430mm in length, making it well-suited to 17-inch outer-barrelled AEGs. Its stainless steel construction adds significant rigidity when compared with brass barrels, meaning no amount of rapid fire can cause this barrel to flex, and its finely polished internal surface should guide your BBs onto target with minimal interruption to its flight path.

If you've decided to join the dark side and HPA your M4, this set will sort you out! The Storm Airsoft HP-R Storm System HPA Engine is a complete drop-in conversion kit for rear-wired version 2 gearboxes, packaged with everything you need to convert your AEG, bar the usual HPA regulator, airline and hose.

The included FCU offers a wide range of adjustable parameters, including programmable fire modes, rate of fire adjustment, and nozzle dwell time adjustment, ensuring reliable feeding with every shot. While it is a drop-in kit, this set will require a certain amount of familiarity with AEG internals and HPA. Luckily, Storm Airsoft provides a useful installation video which makes the process even easier.

Benefits of running HPA over a standard AEG gearbox include minimal FPS deviation between shots for improved accuracy, near-instantaneous trigger response for cranking out those double taps and a wide range of tuning options and adjustments, perfect for casual skirmishers looking to take their build to the next level. If you want the competitive edge HPA provides with minimal effort, the Storm Airsoft HP-R Storm System HPA Engine is the way to go!

If you need a replacement lower receiver for your M4/AR-15 AEG, this is perfect for you! This Specna Arms Lower Receiver is an original replacement part for the Specna Arms CORE™ series, but is compatible with most M4/AR-15 AEGS, thanks to its standard shape and dimensions.

It is constructed from polymer, features a preinstalled fire selector, as well as some cool-looking Specna Arms trademarks. This is a great replacement part to get your old Airsoft platforms back up and running. It's affordable and lightweight, making it a perfect part for your loaner/beginner replica!

Need a new cylinder for your Version 2 gearbox? This Specna Arms Type 2 Cylinder is a top-tier replacement from the Edge series, built for performance and reliability. Its polished inner surface reduces friction for smoother operation and better air efficiency.

As a Type 2 cylinder, it features a precision port designed to vent excess air, perfect for AEGs running inner barrels between 270mm and 430mm. Compatible with both Version 2 gearboxes, this is a solid upgrade for experienced techs who know their way around AEG internals.

If you need a quick, cheap replacement piston head for your Assault rifle, you've come to the right place. The Specna Arms Replacement Piston Head for V2/3 Gearboxes is identical to the piston head that comes in CORE series platforms. This means that, whilst it's nothing special, it is reliable and good enough to be installed in a stock platform. It is the perfect spare part to have around for your V2 and V3 gearboxes.

The Specna Arms Polymer Rotary HOP-Up Chamber is an affordable replacement part, perfect for fixing up your Airsoft rifle! This is a complete HOP-up chamber and comes with all the necessary pieces for installation, including the HOP-up rubber and nub.

The main chamber is constructed from durable polymer and is compatible with all M4-style AEGs which have V2 Gearboxes. It is an affordable solution to mend your platforms with damaged or old HOP-up chambers. The Specna Arms HOP-up chamber is a great fix for your old rifles that are sitting collecting dust.

If you need a new cylinder head to fix up your old Airsoft rifle with a version 2 gearbox, this is for you! The Specna Arms CNC Cylinder Head For Version 2 Gearbox is constructed from CNC-machined aluminium and is fitted with two O-rings to seal any gaps between it and the cylinder for perfect efficiency and minimal air loss.

It also has a sound-dampening pad installed on the rear face, which reduces the whirs of your gearbox and protects the piston head from repeated impacts. A replacement original part for the Specna Arms EDGE series, this cylinder head is also compatible with most version 2 gearboxes!

If you're working on a featherweight M4 build, Specna Arms has the buffer tube for you! The Aluminium Alloy Buffer Tube for M4/AR-15 AEG is compatible with most Airsoft M4/AR-15 platform AEGs and should also fit AR-9 AEGs, which use the same stock mounting lug as standard Marui-spec M4 AEGs.

Providing 6 positions of stock adjustment for whatever M4/AR-15 sliding stock you mount, the tube is constructed from Aluminium Alloy with a glossy finish and is solid as a rock, despite its ultra-low weight. The set also includes the correct length mounting bolt and spacer, so you won't have to work too hard to fit it!

If your ARCTURUS AK12 has a damaged receiver, this is the perfect replacement! It is constructed from steel, meaning it is very durable and realistic feeling. It has detailed mock rivets and realistic stamped receiver markings, which are perfect for those who like keeping their kit as true to life as possible.

This replacement receiver is compatible with the ARCTURUS AT-AK12; it is unclear whether it is compatible with other brands or versions of the AK platform. If you need a new replacement part for your favourite ARCTURUS AK, the ARCTURUS AT-AK12 Full Steel Receiver should be exactly what you want!

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.

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!

If you're looking for accuracy improvements for your M4/AR-15 AEG, the Delta Armory TRINITY R-Hop Bucking Bundle for AEG is what you need to tighten your groupings. 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 TRINITY bucking is diamond-shaped, similar to the Maple Leaf Super bucking, intended to improve accuracy by applying backspin more consistently. The advantage of using a TRINITY 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're looking for tighter groupings from your Airsoft AEG, the TRINITY R-HOP Bucking Bundle is the one to go for!

Whether you're building a DMR or simply want more range from your standard AEG, an R-HOP kit can make all the difference. Unlike other R-HOP kits on the market, the Trusight Tru-Hop Gen.3 is designed to be effectively a drop-in installation, with no need for adding patches of various sizes and includes both the HOP-up bucking and a concave HOP-up nub.

The set is designed to be widely compatible and should fit most Airsoft AEG spec inner barrels, though due to its enlarged contact patch, it will only work with inner barrels with a window measuring approximately 5mm in length x 1.7mm in depth. If you are happy to get stuck in with your AEG internals and you're looking for range and accuracy improvements, the Trusight Tru-Hop Gen.3 Hop-Up Rubber is what you need!

If you are looking for a replacement piston on the cheap with no performance compromises, CYMA to the rescue! The CYMA Steel Tooth Piston Set w/Piston Head includes the piston itself, a piston head and a piston head O-ring. The piston has a full 15-tooth rack of steel teeth, improving strength while keeping overall weight manageable, making it great for high performance builds. The set is designed for version 2 and version 3 gearboxes and will be provided in a random colour; either blue or green.
