All Airsoft Gas Blowback Internal Parts

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!

Fix up your old mags with Army Armament Magazine Followers! This teeny, tiny part tends to take its fair share of wear and tear during long-term use and is a great replacement to have on hand if you have plenty of Army Armament Hi-capa mags at your disposal.

This is a replacement original part designed for Army Armament Hi-capa, JW3, JW4, R504/604 and R608 magazines to name but a few, but may also work with other brands' mags, though we can't confirm this. If you are having feeding issues, replacing the follower is far cheaper than getting a new mag!

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.

If you want more recoil and higher muzzle energy from your Tokyo Marui M&P9 GBB, the CowCow 150% Hammer Spring for TM M&P9 Series is what you need. This replacement hammer spring is rated at 150% of the strength of the original spring, meaning your hammer will hit the knocker valve harder and release more gas, translating into harder felt recoil and higher FPS. Naturally, this will shorten the lifespan of your M&P so proceed with caution if this is your first time upgrading a GBB pistol.

If your grip safety is worn out, this replacement should cure that! The KJ Works Grip Safety for 1911 GBB Pistols is a replacement original part for the KJ Works 1911 GBB pistol series but should also fit most Tokyo Marui and TM clone 1911 GBB pistols. The grip safety is constructed from alloy and finished in black. Please note, this part may require modification to install and as such we recommend it only to experienced Airsofters with a decent amount of tech knowledge.

If you have stored your grenade for too long or in the wrong conditions, fear not! This kit includes exact replacement O-rings and washers for the APS Hell Fire grenade. It even comes with a tiny bottle of pure silicone lubricant, how thoughtful!

If you are planning a Hi-capa overhaul the Custom Hammer from Laylax Nine Ball is a great choice to not only improve the feel of your trigger but add some style points too. This hammer is a skeletonised design with weight-reducing ports machined into the hammer in a hexagonal shape, giving the hammer an ultra-modern look. The hammer is constructed from aluminium, keeping the weight low for maximum performance whilst boasting added strength when compared to most alloy hammers provided out of the box.

If your MK1 Pistol or Tactical Sniper has a leaky mag, this might solve it! The KJ Works Magazine Base Seal for MK1 NBB Pistol is a replacement original part for the ASG/KJW MK1, both the pistol and Tactical Sniper variants. This part replaces the magazine base seal and is the perfect part to have in the toolbox just in case!

Has your R29 magazine become damaged in some way, and a new base is exactly what you need? Well, lucky for you, this is exactly that! The Army Armament Replacement Baseplate for R29 GBB is a replacement part designed for R29 magazines but it should be compatible with other 1911 magazines that are Tokyo Marui clones. However, modification may be required and you should only undertake this modification if you are absolutely confident in your abilities.

It comes with the magazine base and gasket, it does not include a gas inlet valve. It is also recommended that you use silicone oil whilst installing to minimise the risk of damaging the seals.

The MEC M-Valve from PTS is designed to improve gas efficiency and speed up the cyclic rate of your KWA/KSC GBB pistol or SMG. 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 or bolt.

As far as Hi-capa parts go, Airsoft Masterpiece are currently producing some of the best the Airsoft world has ever seen! The Steel Grip safety Type 2 replaces your original beavertail grip safety with a precisely machined steel part, guaranteed to perform when you need it!

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 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'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 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 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.

If your KJ Works B9/92 has trigger issues, this might be the key to getting it running again. 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'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!

A kit which allows you to increase your FPS and Accuracy of your Gas Blowback WE Europe Pistols by extending your Pistol's Inner barrel.

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.
