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!

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!

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 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 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.

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.

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. 

A pre-built drop in hop-up unit and barrel set up built by Maple Leaf with their best parts already included in it. The kit can be dropped into any Tokyo Marui / KJ Works M1911 / MEU Series gas blowback Airsoft pistol for instant results. The set includes an alloy Hop-Up unit, 60 Degree hop-up rubber and Crazy Jet Inner barrel for high performance and improved accuracy. This is perfect for those who are looking to upgrade their pistol with minimum effort.

Looking for more recoil from your EU series GBB pistol? Installing a stronger hammer spring should do the trick! This 140% Hammer Spring from CowCow replaces the original hammer spring in your Tokyo Marui based EU series pistol and provides additional force for each hammer strike, releasing more gas and providing higher FPS and improved recoil and slide speed! This part is constructed from high strength spring steel and is hard-coated to prevent corrosion.

If you want your sidearm to be capable of really reaching out, a HOP-up upgrade should be top of your list! 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!
