Gas Blowback Internal Parts

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!

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 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!

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 you want to tighten your groupings and get maximum accuracy from your GBB or VSR setup, the Maple Leaf 2023 Decepticon HOP-up Bucking for VSR/GBB is the HOP-up rubber you need! Also known as the "Desepticons" bucking by Maple Leaf, this is the 2023 version with a refined shape and packaged with an air-seal promoting C-ring which also enhances feeding reliability. Compatibility-wise, this bucking is designed for unbridged VSR-10 and GBB pistol inner barrels.

The Decepticon makes use of a flat shield-shaped contact patch and is ideally paired with a Maple Leaf I-Key but also works with standard HOP-up arms/tensioners. When compared to its sister bucking, the Autobot, the Decepticon is made for maximum accuracy with a slight range sacrifice while the Autobot is focussed purely on long range.

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. 

The MEC HOP rubber/bucking is precision moulded and has a slightly narrower inner diameter at the entrance and extra coverage for the top of the barrel cut area for a vastly improved air seal. This HOP rubber provides two points of contact with the bb with equal pressure on either side, improving effective range and consistency.

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!

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.

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!

The Maple Leaf HOP-Up Chamber for Umarex/VFC Glock is compatible with the Umarex/VFC Glock 17 Gen.5, Glock 19 Gen.4, Glock 19X and Glock 45 GBB pistols and is constructed from alloy for improved strength. The unit is supplied with two HOP-up arms with one pre-installed, giving you a spare to keep handy or modify for some experimental HOP-up setups.

If you want to shock the enemy by landing a hit with your pistol at long range, the Maple Leaf HOP-Up Chamber for Umarex/VFC Glock is the key!

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!
