An aftermarket upgrade/replacement Inner Barrel and HOP Unit/Rubber for Hi-Capa Series Airsoft Pistols, specifically the Army Armament R601. This awesome package provides you with a Precision 6.02mm Inner Barrel, as well as a HOP Chamber, ML 70° Bucking and 'I-Key Delayer', to improve range, accuracy and precision.

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!

The Maple Leaf Autobot HOP-up rubber has gained a reputation as one of the best upgrade components if you want to extend the range and improve the accuracy of a TM based GBB pistol, VSR/bar-10 sniper rifle, or GBBR with TM GBB HOP-up bucking compatibility. The Autobot has a wide and flat contact patch to help stabilise your BB in flight and extend your range. This bucking is also designed to ensure your BB is chambered consistently with every shot, guaranteeing impressive accuracy when compared to standard HOP-up buckings. This is the latest variant of the Autobot and is constructed from silicone instead of standard rubber, offering greater resistance to temperature changes.

If you want to upgrade your Umarex Glock and build a sleeper of a long ranged pistol setup, this is the HOP-up unit you need! The Maple Leaf HOP-Up Chamber for Umarex/VFC Glock is compatible with the Umarex/VFC Glock 17, Glock 19, 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. 

The tolerances of this unit are far more precise than the original, offering better air seal and gas efficiency, translating into better effect on target and better consistency. 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!

An absolute monster of an upgrade to make to your weapon. The external surface is ribbed to keep your inner barrel more stable inside your hop up unit with next to no play at all after you have fully re-assembled your Airsoft weapon.

A high quality replacement Hop up rubber, made to 70 degrees of hardness, and designed for VSRs, as well as KJW and WE Airsoft designs.

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 WE,  Tokyo Marui, or VFC EU-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.

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.

Whether your HOP-up rubber is worn out or you are seeking an upgrade, the Novritsch HOP-up Bucking for SSP1/SSP5 GBB pistol is one to keep an eye on. This HOP-up bucking is a big reason that Novritsch pistols have such incredible range, and being a VSR/GBB style HOP-up rubber, this should be compatible with most TM-based GBB pistol designs as well as the VSR-10 sniper rifle series.

The HOP-up bucking combo from CowCow is a great buy if you are the type of exacting player who swaps their HOP rubber to get the best possible performance in various ambient temperatures. Included in the set are 3 HOP rubbers/buckings designed for TM based GBB pistols and WE GBBRs, and offer three different levels of hardness for different applications.

Maple Leaf has quickly risen to become the market leader in HOP-up rubbers and inner barrels, and the Maple Leaf Decepticon bucking is no exception. The design of the Decepticon bucking features a narrower entrance to help the BB feed in a consistent spot with each cycle, and a contact patch with a refined shape intended to provide more consistent lift across the entire upper surface of the BB for greater accuracy than standard HOP buckings. This particular bucking is made from silicone, offering greater resistance to temperature changes than rubber equivalents, making it especially useful for a gas blowback rifle or accurized GBB pistol.

If you are looking for more consistency, accuracy and range from your setup you can trust Maple Leaf to provide you with the best solution! The Super Hop Rubber is a refined design based on the TM Pistol and VSR-10 HOP pattern, but with a widened contact area to provide a greater HOP-up effect, spread more evenly across the upper surface of the BB to provide a more consistent and straight trajectory.

An enhanced HOP Unit for Army Armament / Tokyo Marui branded M1911 platform Gas Blowback Replicas, which serves to improve compression and lift achieved from your BBs. It is constructed from Aluminium and comes supplied with the Chamber, HOP Army, Adjustment Wheel, Two Screws and a small O-Ring.

For those Hi-capa builders out there, especially the ones who appreciate the glamour and flair of gold parts, this one is for you! The HOP-up base for TM Hi-capa from Airsoft Masterpiece is precisely machined from brass and finished in gloss gold, and comes with the HOP adjuster gear and tensioner.
