All Airsoft Gas Blowback Internal Parts

If you're after more accuracy and range from your GBB pistol, VSR sniper rifle or GBBR, the 4UANTUM Friction Pro High-Performance VSR/GBB HOP-up Bucking is the key! This cutting-edge HOP-up upgrade set includes an HOP-up rubber/bucking with a uniquely shaped contact patch and an OMEGA-style flat nub, ready to be installed into any VSR sniper rifle, GBB pistol or VSR/GBB compatible GBBR HOP-up unit.

The Friction Pro bucking was developed over 2 years of rigorous testing and, since its launch, has taken the Airsoft world by storm. We've been extremely impressed by the performance of this bucking during testing, offering exceptional range and a remarkably tight grouping, a combination other buckings often compromise on.

Designed to perfectly centre your BB with each shot and lift up to 0.48g heavy-weight BBs, the Friction Pro provides positively epic long-range performance and is ideal for accuracy-focussed skirmishers who want impressive range without a wider grouping. Whether you're running low-capacity GBBR mags and need to make every shot count or you need your pistol to reach out and surprise the enemy team, the 4UANTUM Friction Pro High-Performance VSR/GBB HOP-up Bucking is what you need!

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!

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'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!

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.

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 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. 

The Army Armament Green Gas Valve Kit for AA Hi-capa & 1911 GBB is what you need if your magazine leaks from the fill valve or knocker valve. The set includes replacements for both, complete with pre-installed rubber O-rings. 

This set should be suitable for most Hi-capa and 1911 GBB pistol magazines but is specifically designed for Army Armament R26, R27, R28, R29, R31, R32, R45, R501, R601, R603 & R604 magazines. 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!

If you want your sidearm to be capable of really reaching out, a HOP-up upgrade should be top of your list! The Maple Leaf HOP-up Chamber for VFC/WE/TM EU-Series GBB is constructed from alloy and supplied with a steel HOP-up arm and aluminium "I-key" style tensioner, promising tighter tolerances than the stock HOP-up unit which should translate to better air seal qualities, consistency and thus better accuracy downrange.

This set is compatible with VFC, WE and Tokyo Marui EU-series GBB pistols but should also fit most Tokyo Marui clone EU-series pistols, though as always, we recommend upgrade parts only for the knowledgeable and confident!

If you have hammer issues with your Army Armament Hi-Capa, this should help! The Hammer and Strut for Hi-Capa GBB Pistols from Army Armament is constructed from Aluminium and an original replacement part for the Army Armament Hi-Capa GBB series, including the R501, R504, R603, R608, R609 and potentially others. The set includes both the hammer and hammer strut and should be compatible with most TM clone Hi-Capa pistols, though it may need mods for anything other than Army Armament 'Capas. 

If you want to upgrade your Umarex Glock and build a sleeper of a long ranged pistol setup, this is the HOP-up unit you need! 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!

If you've got some old MWS, CGS or Hi-Capa mags to refurbish, the CYMA CGS / MWS / Hi-Capa GBB Magazine Output Valve is what you need! This set is a complete replacement original knocker valve (aka output valve), the valve at the top of the magazine which is struck by the valve knocker. 

Compatibility-wise, this should fit Tokyo Marui MWS ZET System Mags, CYMA CGS GBBR magazines, Tokyo Marui Hi-Capa mags and some TM clone Hi-Capa magazines (though this is not guaranteed). Whether you like to keep spares on hand so you're always battle-ready or your mags are a bit tired and need a revamp, the CYMA CGS / MWS / Hi-Capa GBB Magazine Output Valve will do the trick!

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. 

If you're building out your Shadow 2 GBB and seeking more accuracy, the Maple Leaf Complete HOP-Up Chamber for KJW/ASG Shadow 2 GBB is an easy way to get there! This complete HOP-up chamber group is practically a drop-in fit and pre-built so you don't have to do any of the fiddly stuff!

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!

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. The valve is constructed from high strength brass with rubber O-rings and should help improve the performance of your pistol in cold weather, and speed up the cyclic rate if you have installed a heavy steel slide.

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. When installed into your TM based Hi-capa or 1911 GBB this part should help improve shot to shot consistency and provide longevity far beyond the original parts.

The CYMA CGS Feed Lips & Gas Route Bucking Set for ZET System M4 GBBR provides 5 sets of feed lips and 5 gas route buckings for your magazines, allowing you to fix up old mags or keep spares handy just in case. 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 you want to take pure advantage of the inherent modularity of the VORSK VMP-2, these Complete Trigger Groups are the key! Available in semi-auto only for DMR builds or select fire (semi/full auto) for assault rifle setups, the VORSK Complete Trigger Group for VMP-2 Series is constructed from alloy with steel springs, pins and screws.

If you're rocking the VMP-2D or VMP-2MD, the select fire version will allow you to convert your DMR into an assault rifle, though you'll also need a low power nozzle to keep your build site legal. Installing the semi-auto only version in the VMP-2M will lock it to semi-auto, allowing you to pop a high power nozzle inside and run it as a compact DMR!

Each trigger group comes pre-built and equipped with ambidextrous fire controls, making it an almost literal "drop in" installation. No need to fiddle with small springs and awkward little screws installing these! Despite the super easy installation, any internal modification made will void the VMP-2's original 12-month warranty so we only recommend these for the pros!
