The kit can be dropped into any WE,  Tokyo Marui, or VFC EU-Series gas blowback Airsoft pistol for instant results.

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, Glock 19, 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 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.

An absolute monster of an upgrade to make to your weapon. The external surface is ribbed to keep your inner barrel more stable inside your hop up unit with next to no play at all after you have fully re-assembled your Airsoft weapon.

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. 

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.

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!

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.

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!

The HOP-up bucking combo from CowCow is a great buy if you are the type of exacting player who swaps their HOP rubber to get the best possible performance in various ambient temperatures. Included in the set are 3 HOP rubbers/buckings designed for TM based GBB pistols and WE GBBRs, and offer three different levels of hardness for different applications.

This part is constructed from oil-resistant rubber, meaning it will not absorb lubricant and expand, preventing cycling issues from developing over long term use. This part is an essential for anyone going for the absolute maximum performance possible from their AAP-01.

Maple Leaf has quickly risen to become the market leader in HOP-up rubbers and inner barrels, and the Maple Leaf Decepticon bucking is no exception. The design of the Decepticon bucking features a narrower entrance to help the BB feed in a consistent spot with each cycle, and a contact patch with a refined shape intended to provide more consistent lift across the entire upper surface of the BB for greater accuracy than standard HOP buckings. This particular bucking is made from silicone, offering greater resistance to temperature changes than rubber equivalents, making it especially useful for a gas blowback rifle or accurized GBB pistol.

If you are tuning up your Hi-capa GBB, whether it's for an upcoming competition or the next CQB skirmish, a recoil buffer kit could be just what you need to give your setup a bit more speed! The Shock Buffer from Airsoft Masterpiece provides 4 rubber buffer pads and 4 steel spacers, allowing you to adjust the length of travel of your slide from short enough that it only just loads a BB, to full length with a single buffer pad to reduce wear. For faster semi-auto follow up shots, this is what you need!
