- Replacement O-ring set
- For Airsoft gas magazines
- Fix up your old leaky mags!
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!
- Replacement magazine fill valve
- For GBB magazines
- Includes an O-ring
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.
- Shield-shaped contact patch
- Flat/R HOP style Rubber
- For GBB & VSR-10 Unbridged barrels
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!

- Brass with Rubber O-rings
- Replacement original parts
- For Army Armament Hi-capa & 1911 GBB
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!
- Polymer construction
- Replacement Hi-capa feed lips
- Fix up your old magazines
If you have dropped a mag mid game you probably have a set of broken feed lips, but fear not! The Army Armament Magazine Feed Lips for Hi-capa GBB is designed to replace the original feed lips of AA Hi-capa magazines whether they are cracked from an accidental drop or just getting a bit worn out.
- Replacement hammer and hammer strut
- For R601 JW3 GBB Pistol
- Alloy and steel construction
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.
- Baseplate seal
- Reduces Leaking
- Improves Gas Seal
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. With a properly fit and lubricated seal you should never experience a leak again, just ensure you coat the seal in silicone based lubricant prior to fitting it, and be gentle! These things may snap under too much tension.

- CNC 7075 Aluminium construction
- Adjustable valve - Tune FPS to the limit!
- For TM ZET System M4 MWS & CGS M4 GBBRs
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!
- Spring steel construction
- Replacement original part
- For KJ Works B9/B92 GBB Pistols
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!
- Steel construction
- Spring with safety & slide stop plunger
- Original Army Armament replacement part
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.
- Complete trigger group
- Pre-built for easy installation
- Semi-auto only or select fire versions
If you want to take pure advantage of the inherent modularity of the VORSK VMP-2, these Complete Trigger Groups are the key! Available in semi-auto only for DMR builds or select fire (semi/full auto) for assault rifle setups, the VORSK Complete Trigger Group for VMP-2 Series is constructed from alloy with steel springs, pins and screws.
If you're rocking the VMP-2D or VMP-2MD, the select fire version will allow you to convert your DMR into an assault rifle, though you'll also need a low power nozzle to keep your build site legal. Installing the semi-auto only version in the VMP-2M will lock it to semi-auto, allowing you to pop a high power nozzle inside and run it as a compact DMR!
Each trigger group comes pre-built and equipped with ambidextrous fire controls, making it an almost literal "drop in" installation. No need to fiddle with small springs and awkward little screws installing these! Despite the super easy installation, any internal modification made will void the VMP-2's original 12-month warranty so we only recommend these for the pros!
- Brass / rubber construction
- Replacement original part
- For MWS/CGS/Hi-Capa GBB mags
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!
- Steel construction

- CNC Aluminium build
- QD Sling socket built-in
- Mount 1913 stocks to your Saiga-12K GBB
If you're searching for parts to customise your TM Saiga-12, the Laylax 1913/20mm Picatinny Rear Stock Base for TM Saiga-12K GBB will give it a touch of modernity! Made from CNC-machined aluminium with a QD sling socket built in, this stock adapter allows cutting-edge 1913/20mm Picatinny stocks to be fitted in seconds and switched out at will.
The 1913 interface allows you to choose from minimalist folding stocks, AR buffer tube adapters, Visor/Respirator stocks ideal for full face protection and plenty more, just like the ultra-modern MCX and MPX platforms. We think the Saiga 12 would look mint with the Airsoft Artisan MCX Triangle Folding Stock, but with this adapter on board, your options are practically unlimited!
- Gas route bucking set
- Set of 5 - 70 Degrees hardness rubber
- For CYMA CGS, Double Eagle & TM ZET system M4 GBBR mags

If you've lost a safety catch for your Army Armament Hi-Capa, you're in luck!
