All Airsoft Gas Blowback Internal Parts

If you want to tighten your groupings and get maximum accuracy from your GBB or VSR setup, the Maple Leaf 2023 Decepticon HOP-up Bucking for VSR/GBB is the HOP-up rubber you need! Also known as the "Desepticons" bucking by Maple Leaf, this is the 2023 version with a refined shape and packaged with an air-seal promoting C-ring which also enhances feeding reliability. Compatibility-wise, this bucking is designed for unbridged VSR-10 and GBB pistol inner barrels.

The Decepticon makes use of a flat shield-shaped contact patch and is ideally paired with a Maple Leaf I-Key but also works with standard HOP-up arms/tensioners. When compared to its sister bucking, the Autobot, the Decepticon is made for maximum accuracy with a slight range sacrifice while the Autobot is focussed purely on long range. If you're all about accuracy, the Maple Leaf 2023 Decepticon HOP-up Bucking for VSR/GBB belongs in your build!

If your priority is extending range and you run a GBB pistol or VSR-10 platform sniper rifle, the Maple Leaf 2023 Autobot HOP-up Bucking is calling your name! Also known as the "Aotubot" by Maple Leaf, this bucking is designed for pure range, with a shield-shaped contact patch for maximum contact area with your BBs and an impressive HOP-up effect. Being the 2023 model, this set also includes an air-seal promoting C-ring which also helps improve feeding. Compatibility-wise, this bucking is designed for unbridged VSR-10 and GBB pistol inner barrels.

Naturally, the Autobot is designed for use with heavy BBs (0.28g+) and is ideally paired with a Maple Leaf I-Key but works fine with standard HOP-up arm/tensioner setups. When compared to its sister bucking, the Decepticon, the Autobot is made for pure range and the Decepticon is for tighter groupings at shorter ranges. If you need maximum range, you need the Maple Leaf 2023 Autobot HOP-up Bucking for VSR/GBB!

If you have a pile of leaky mags, now is the time to fix them up! The WADSN Gas Magazine O-ring Repair Set includes 10 O-rings of 7 different sizes, designed to replace the O-rings of the knocker valve and fill valve in most Airsoft gas magazines. The set is supplied in a clear polymer organiser case to keep everything neat and includes a set of polymer installation tweezers to make installation without damaging the O-rings considerably easier. If you have a lot of leaky mags gathering dust, this set is the key to giving them a new lease of life!

The MEC HOP rubber/bucking is precision moulded and has a slightly narrower inner diameter at the entrance and extra coverage for the top of the barrel cut area for a vastly improved air seal. This HOP rubber provides two points of contact with the bb with equal pressure on either side, improving effective range and consistency.

If you're seeking maximum HOP-up performance and are committed to using heavy BBs, the Maple Leaf 2023 MR HOP Bucking for VSR/GBB belongs in your build. The MR HOP-up Bucking offers a wider and longer “R-HOP” style contact patch for increased HOP-up effect and extended range with heavy BBs. The MR HOP also uses a shield-shaped groove around the contact patch to allow it to stretch and add to the strong HOP-up effect along with an air seal improving C-ring which ensures the bucking is firmly fitted to the barrel and unable to slip or rotate.

MR stands for “Maximum Range”, a design based on home-brewed R-HOP buckings, intended to prioritise range over grouping size and is best used paired with a Maple Leaf OMEGA or OHM HOP-up nub. Compatibility-wise, this version of the MR HOP is designed for unbridged VSR-10 and GBB pistol inner barrels but as always, a certain amount of expertise and tuning may be required to install it, though it will be far less work than the R-HOPs of old!

An upgraded hammer is a great foundation to any upgraded AAP-01 build, especially if you are an HPA user! The CowCow SS Hammer is CNC machined from strengthened alloy with a stainless steel finish, and MAF polishing technology is applied to its exterior surfaces to reduce friction between parts and ensure smooth operation of the pistol.

If you have dropped a mag mid game you probably have a set of broken feed lips, but fear not! The Army Armament Magazine Feed Lips for Hi-capa GBB is designed to replace the original feed lips of AA Hi-capa magazines whether they are cracked from an accidental drop or just getting a bit worn out. 

If you have a magazine which leaks from the fill valve, or your mag is a bit old and the valve has taken a hammering over the years, a replacement valve is the way to go. This Specna Arms valve replaces the fill valve in your magazine with a nice fresh one, complete with an O-ring to ensure there are no leaks! This valve will require a valve key to install.

If you are building out your dream Airsoft Hi-capa GBB pistol, the CowCow Stainless Steel hammer strut would be a great addition if you require an improved trigger feel and better mechanical engagement. This part is constructed from stainless steel with a titanium coating to prevent corrosion and warping.

The KJ Works Trigger Spring for B9/92 GBB Pistol is a replacement original part for the KJ Works B9 and B92 GBB pistol series and is constructed from spring steel.

We recommend a valve key for easy installation. Breath new life into your pistol or save money fixing an old mag instead of replacing it!

The Maple Leaf HOP-Up Chamber for Umarex/VFC Glock is compatible with the Umarex/VFC Glock 17 Gen.5, Glock 19 Gen.4, Glock 19X and Glock 45 GBB pistols and is constructed from alloy for improved strength. The unit is supplied with two HOP-up arms with one pre-installed, giving you a spare to keep handy or modify for some experimental HOP-up setups. 

The tolerances of this unit are far more precise than the original, offering better air seal and gas efficiency, translating into better effect on target and better consistency. If you want to shock the enemy by landing a hit with your pistol at long range, the Maple Leaf HOP-Up Chamber for Umarex/VFC Glock is the key!

The MEC M-Valve from PTS is designed to improve gas efficiency and speed up the cyclic rate of your Tokyo Marui EU17 GBB pistol.

This hammer is an original replacement part for the Army Armament R601 JW3 GBB pistol but may also fit other Army Armaments Hi-capa based GBB pistols. A hammer is a great spare to have in the tool kit if you use your JW3 pistol heavily, as over time these tend to wear out due to the repeated impacts on the hammer with every shot. Having a spare hammer on hand for worst-case scenarios can help avoid disappointment and potentially a long wait for replacement parts and allow you to have your pistol back up and running quickly for its next outing.

If you've got leaky M4 ZET system mags, these could help fix them up! The CYMA CGS Enhanced M4 ZET System Gas Route Bucking 70 Degrees - Set includes 5 gas route buckings/seals for TM ZET system M4 GBBR magazines constructed from 70-degree hardness rubber for temperature resistance and improvements in strength. 

Not only a handy spare to have on hand for anyone with TM ZET system M4 magazines, these gas route buckings can also help improve gas efficiency by reducing gas leakage between the magazine and nozzle, especially if you've installed a CGS nozzle or bolt carrier group into your TM. The CGS Enhanced M4 ZET System Gas Route Bucking is compatible with Tokyo Marui and CYMA CGS M4 magazines and should also fit the Double Eagle M4 ZET system magazines.

The set includes a Maple Leaf 6.02mm Tightbore inner barrel made from stainless steel, the Maple Leaf HOP-up chamber and a Maple Leaf Autobot 60° HOP-up bucking paired with the much-lauded Maple Leaf I-Key. Compatibility-wise, the Complete HOP-Up Chamber should work flawlessly with both ASG and KJ Works CZ Shadow 2 GBB pistols. Installing this set should boost FPS and gas efficiency slightly thanks to tighter tolerances, improve accuracy potential and extend range, giving your sidearm-sized platform a primary-like punch!

This is a set of spare O-rings for Novritsch SP1, SSP2 & SSP5 V2 magazines. They are the perfect replacement parts for magazines that are leaking gas. Become a maintenance master and fix your leaky mags, rather than spending extra on new ones. Should your magazine spring a leak, a spare set of O-Rings is always handy.

This set is designed for TM ZET system M4 GBBR mags and should also fit clones of the TM design, including CYMA CGS M4 GBBR mags and Double Eagle M4 GBBR mags. 

The included feed lips are an ideal spare part to have on hand; as any experienced GBBR user will know, dropping a hefty gas mag is likely to break the lips and render the magazine useless. The Gas Route Buckings are also very useful in the event your magazine develops a leak from the top, and can also help improve gas efficiency should you decide to upgrade your TM or Double Eagle M4 GBBR with a steel CGS bolt carrier group. If you're getting in deep with ZET system GBBRs, this set belongs in your toolbox!

If your Tokyo Marui ZET system M4/AR-15 needs some steel to keep it strong, the CYMA CGS Adjustable Trigger Box for TM ZET System M4/AR-15 GBBR belongs on your shopping list! This complete trigger box is ready to drop in and contains full steel trigger components which should last practically forever in normal use. The box is compatible with both CYMA's CGS M4/AR-15 GBBR series and Tokyo Marui ZET system M4/AR-15 GBBRs. 

Along with its steel construction, the extra perk of this box is its ability to adjust the hammer stroke strength, translating into adjustable FPS by varying the force with which the hammer strikes the valve knocker. As always, we recommend internal upgrades only for those who are confident in how to install them, but with this trigger box being pre-built, most of the hard work has been done for you!

If your grip safety is worn out, this replacement should cure that!

Nozzles are a known failure point for GBB pistols and as reliable as the SSP2 is, it's always wise to have spare parts so you can keep your beast of a 'Capa up and running!

A silicone rubber seal designed to fit on the bottom of your Hi Capa magazine internally, to replace old and work out seals and reduce leaks. With a properly fit and lubricated seal you should never experience a leak again, just ensure you coat the seal in silicone based lubricant prior to fitting it, and be gentle! These things may snap under too much tension.
