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're running the VMP-2D or VMP-2MD and want to tune muzzle energy, the VORSK Replacement Nozzle for VMP-2D & VMP-2MD is what you need! Available in a range of power levels, including 300 FPS, 330 FPS, 430 FPS and 450 FPS, these nozzles are colour coded so you can tune to perfection without the confusion.

While these nozzles are compatible with all VMP-2 variants, the stated power level only applies to the VMP-2MD and VMP-2D barrel lengths. Muzzle energy will be slightly higher with longer barrel lengths and slightly lower with shorter barrel lengths, so please keep this in mind. The nozzle spring is also pre-installed in each nozzle to make installation that bit easier. If you're the type to take full advantage of your VMP-2's modularity, the VORSK Replacement Nozzle for VMP-2D & VMP-2MD was made with you in mind!

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!

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. 

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 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!

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.

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!
