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!

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 are after a bit more accuracy from your GBB pistol, a tightbore barrel is the easiest and most effective solution! Introducing the 6.03mm Tightbore Inner Barrel from Nine Ball, one of the best inner barrels you can treat yourself to. The Inner Barrel features standard inner barrel cuts, meaning the barrel is compatible with TM-based GBB pistols with the VSR style bucking (WE, Umarex G series etc.). Due to its length, we recommend this for GBB pistols, specifically HI-CAPA 5.1 and 4.3.

The inner barrel is constructed from stainless steel, with a highly polished internal surface for minimal friction and a deep and smooth crown to ensure your BB leaves the barrel smoothly and consistently. This barrel is cut for either VSR/GBB style HOP buckings.

If you have a leaky M887x series shotgun this is what you will need to fix it. Replacement complete O-ring set, useful to repair your old unloved Shotgun or refresh your well loved Shotgun.

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. This is the spring that resets the trigger, so if your trigger gets stuck back after one shot this might solve your issue!

If you love your Novritsch pistols and want to keep them shooting pristine, keeping a spare Novritsch SSP1/SSP5 Nozzle can't hurt! This polymer loading nozzle is compatible with Novritsch SSP1/SSP5 GBB pistols and is a fantastic part to have lying around just in case a catastrophe strikes, especially if you often find yourself relying on your sidearm. If you're very attached to your Novritsch SSP1/SSP5 pistols and don't ever want them to sit around awaiting spare parts, grab this to put your mind at ease and get your Novritsch pistols back on the battlefield!

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 your Hi-Capa to shoot like a beast, the Maple Leaf Steel HOP-up Chamber Set for Hi-Capa GBB Pistols belongs inside. This steel HOP-up chamber should improve consistency and air seal by tightening tolerances between your HOP-up bucking and air nozzle and is far stronger than standard alloy HOP-up units as a bonus.

Included in the set is an enhanced HOP-up arm, a CNC machined adjuster dial and the legendary Maple Leaf I-Key which is designed to provide a "flat HOP" effect and is ideally used with heavy BBs (0.28g+). Compatibility-wise, this unit is designed for Tokyo Marui Hi-Capa GBB pistols and should fit most other Hi-Capas, though modification and tuning may be required. If you want to use your Hi-Capa as a primary and need range to compete with rifles, the Maple Leaf Steel HOP-up Chamber Set for Hi-Capa GBB Pistols is ideal!

If you love your SSP18 and want to keep it shooting in the long term, having a Novritsch SSP18 Complete Nozzle can't hurt! This polymer loading nozzle is compatible with Novritsch SSP18 GBB pistols and is a fantastic part to have lying around to pre-empt potential disaster, especially if you use full auto a lot. If you're very attached to your SSP18 and don't ever want it to sit around awaiting spare parts, grab this to put your mind at ease!

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!

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.

Fix your Novritsch magazines so they're skirmish-ready, or have some spare parts should the worst scenario occur. The Novritsch SSP2 O-Ring Set gives your magazines a second chance at fighting!

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!

If you have a broken magazine it's a real shame to have to bin it! Luckily Army Armament have released their 1911 magazine follower as a separate part, allowing you to repair your mag if you have had follower issues, or even replace a worn follower for more reliable feeding.

If you have an Army Armament 1911 GBB with a broken nozzle you are in luck! The Army Armament Nozzle for 1911 GBB Pistol is a replacement original part designed for the Army Armament 1911 GBB series, including the R26, R28, R31 and R32 pistols. This nozzle may also work with TM-compatible 1911 pistols from other brands, but as always we only recommend brand mixing for the experts as this may require fine-tuning and modification.

Nozzles are a known failure point for pistols and as reliable as the SSX23 is, it's always wise to have spare parts so you can keep your beast of a pistol up and running!

Although this comes with an attachment screw and rubber O-ring, please be aware that this base plate does not come with a valve.

Whether your HOP-up rubber is worn out or you are seeking an upgrade, the Novritsch HOP-up Bucking for SSP1/SSP5 GBB pistol is one to keep an eye on. This HOP-up bucking is a big reason that Novritsch pistols have such incredible range, and being a VSR/GBB style HOP-up rubber, this should be compatible with most TM-based GBB pistol designs as well as the VSR-10 sniper rifle series.

A high quality replacement Hop up rubber, made to 70 degrees of hardness, and designed for VSRs, as well as KJW and WE Airsoft designs.
