All Airsoft Gas Blowback Internal Parts

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!

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. 

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 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.

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.

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. 

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!

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.

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!

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.
