All Airsoft Gas Blowback Internal Parts

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 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 you lost a safety from your R28 or R32 1911 GBB pistol, this set should sort you out! The Army Armament Ambidextrous Safety Catches for R28/R32 1911 GBB Pistols includes both the left and right side safety catches, both of which are constructed from alloy. These safety catches are specifically designed for Army Armament 1911 platforms but are potentially compatible with other brands, though you may need to carry out modifications.

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 fixing up your Hi-capa or 1911 you might need one of these! The Slide Stop/Safety Spring and Plunger includes the dual purpose slide stop/safety spring and the plunger for each, making it the perfect replacement set for those who have lost or damaged these parts. All components in this set are constructed from steel, and are designed to fit the Army Armament 1911 and Hi-capa GBB pistols but may fit others based on the Tokyo Marui internal design.

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 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.

Whether you need to tune FPS or seek a more robust, reliable build, the CYMA CGS CNC Aluminium Nozzle Set w/Adjustable Valve for CGS/TM GBBR is a great buy for any TM ZET System M4 or CGS M4 GBBR owner. This nozzle is made from CNC machined 7075 aluminium, making it incredibly strong and well up to a hard life of hard recoil!

The set includes an adjustable NPAS-style valve and a non-adjustable valve, giving you the option to stay versatile with adjustable FPS or stick to a fixed valve for better consistency. Compatibility-wise, this nozzle set is designed for the CYMA CGS M4 GBBR series and is confirmed to fit the Tokyo Marui M4 ZET System GBBR series, and while it should work, we are unable to confirm compatibility with Double Eagle ZET System clones. We can say for certain this won't work in a WE or Golden Eagle GBBR.

If you want to use your GBBR in CQB one day and as a DMR the next, the CYMA CGS CNC Aluminium Nozzle Set w/Adjustable Valve for CGS/TM GBBR is the part you need to make that happen. Far stronger than polymer nozzles and precisely made with CNC machining, if you want to keep your GBBR recoiling hard in the long run, this part is ideal!

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.

An upgrade or replacement stock sear spring for gas blowback pistols. The spring is made of robust steel and therefore will hold its shape better than stock springs, which is perfect for keeping your trigger action to be short and crisp. Due to the springs high tolerance, there would be no need to shave it down to fit in your grip.

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 CowCow Trident Sear spring is designed to replace your original sear spring, and features revised contact surfaces which have been narrowed to prevent excessive friction with other parts. If you are building a high speed Hi-capa or 1911, this is perfect for the job!

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!

Does your AK need a touch of style? Add the 5KU PT-1/3 Stock Adapter for LCT/GHK/CYMA Side Folding AK Receiver and you're halfway there! This adapter allows Zenitco PT-1 or PT-3 multi-adjustable stocks to be mounted to an LCT, GHK or CYMA side folding AK receiver and should also work with most PT-1 and PT-3 clones. Made from robust steel to guarantee it will never fail, the PT-1/3 Stock Adapter from 5KU is the first step to styling up your side folder AK!

If you've had a mishap with your R36 GBBR or you want to keep spares handy just in case, the Army Armament Nozzle for R36 GBBR belongs in your toolbox! This is a replacement original part for the R36 GBBR series and may also fit WE AR36 GBBRs but we cannot confirm that. The set includes a polymer nozzle and a steel nozzle spring which is thoughtfully pre-installed, saving you some fiddling!

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!

If you've damaged your Maten MML's HOP-up, this part might be the fix you need! The PTS Syndicate HOP-up Adjust Ring Guide for MML Maten GBBR; Part [005] is a replacement original part for the PTS Mega Arms Maten MML GBBR, numbered 005.

While it has a strange name, this part of the HOP-up unit effectively functions as the "C-clip" you'll find in most AEG HOP-up units to hold the inner barrel in place and guide the HOP-up adjuster, so if yours is lost or damaged and needs replacement, add this to your shopping list ASAP!

If you're having issues with your STTI ST92F, this part may help! The ST92F Trigger to Barrel Connector from STTI is a replacement original part for the STTI ST92F. This part is made from alloy and numbered "Part 27" in the ST92F manual. It may fit other B9/92 style GBB pistols, but we cannot guarantee it!

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 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!
