All Airsoft Gas Blowback Internal Parts

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!

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 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!

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.

Working on upgrading your AAP-01? If so, the CowCow Stainless Steel Hammer housing would be a great addition to your parts list. This strengthened hammer housing is designed to work with other upgraded AAP-01 components, and prevent upgraded hammers from damaging the original alloy hammer housing. If you are installing a steel hammer in your build why not get ahead of future parts breakages and upgrade the hammer housing while you're at it?
