Airsoft Hop Up Units & Buckings

If you're building an AEG for maximum range, the Maple Leaf Monster HOP-up Bucking for AEG will be an asset to your objective. Designed with a diamond-shaped contact patch to increase surface contact with your BBs, the Monster is ideally used with heavy BBs (0.28g+) and provides increased HOP-up effect, especially when paired with an OMEGA or OHM HOP-up nub.

The Monster is available in a wide range of hardnesses, offering an option for any build objective, from CQB to DMR. Compatibility-wise, this is a standard AEG HOP-up rubber and should fit the vast majority of Airsoft AEGs on the market but may require expertise and tuning to fit. If you're getting out-ranged and want to go from prey to predator, the Maple Leaf Monster HOP-up bucking belongs in your build!

If you're looking for all-round improvements in your HOP-up performance, the Maple Leaf Macaron HOP-up Bucking is calling your name! Designed to fit Airsoft AEGs and enhance both accuracy and range, the Macaron boasts a flat diamond-shaped patch for greater contact area with your BBs, giving a "Flat HOP" style effect when paired with an OMEGA or OHM HOP-up nub.

When compared to the Monster HOP-up bucking, the Macaron's contact patch is slightly less prominent, designed to provide a balance between range and grouping size as opposed to the Monster's focus on pure range. Compatibility-wise, the Macaron should fit most Airsoft AEGs though some level of expertise is required for fitting and tuning. If you want tighter groups and more range, the Maple Leaf Macaron HOP-up Bucking for AEG will do the trick!

If you're jealous of GBB users running the superb Crazy Jet inner barrel, the Maple Leaf Hot Shot HOP-Up Bucking for AEG will level the playing field! This HOP-up bucking is designed for use with standard AEG HOP-up units paired with Maple Leaf's GBB/VSR type Crazy Jet inner barrel, boasting a wedge-shaped concave contact patch with nubs on either side to encourage consistent BB chambering.

While the Hot Shot Bucking may work with other GBB/VSR type inner barrels, it is not compatible with standard AEG inner barrels. Multiple degrees of hardness are available, with an option for almost any BB weight and muzzle energy combination. If you want the performance benefits of the Crazy Jet barrel with your AEG, the Maple Leaf Hot Shot HOP-Up Bucking is essential!

If you want glowing BBs without making your primary any longer, the CYMA Tracer HOP-Up Chamber for M4/AR-15 AEGs is a great shout! This alloy rotary HOP-up chamber integrates a tracer module, just like more expensive alternatives with the option to use red or green tracer BBs. The set includes everything you need to complete the HOP-up chamber build, including the bucking and nub. 

This unit is powered by your AEG's battery through the balance cable, meaning it will only work with LiPo batteries unless you have something home-brewed in mind. The set includes 3 sets of wiring for use with 7.4V LiPo, 11.1V LiPo or custom battery solutions, all of which connect to the pre-wired connector on the HOP-up unit itself. 

While it is designed for use with the CM.097 series and other CYMA Platinum M4/AR-15 AEGs, this unit should work with most M4/AR-15 AEGs on the market, potentially requiring modifications to fit certain brands. Depending on your specific platform, fitting may also require modification to your receiver. As such, we only recommend this unit for those who are comfortable working on AEG internals. If this sounds like you, why not shave off length and weight from your CQB primary with the CYMA Tracer HOP-Up Chamber for M4/AR-15 AEGs?

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.

An upgrade hop bucking for Tokyo Marui and other compatible products. Designed for the Tokyo Marui VSR-10 bolt action and blow back pistols in mind including the Hi-Capa 4.3, Hi-Capa 5.1, M1911A1, SIG P226, SOCOM MK23 and G26. 

If you want tighter groupings and more range, you're not alone! Thankfully, Maple Leaf is here to make your AEG shoot like a laser beam with the OHM Silicone AEG HOP-Up Tensioner; Solid Edition. This HOP-up nub/tensioner is ideally paired with a Maple Leaf HOP-up bucking and like much-lauded "Flat HOP" nubs, is designed to provide a stronger HOP-up effect for heavy-weight BBs and to reduce side-to-side shot deviation, improving accuracy and range as long as you do your part.

The OHM Solid Edition is available in two different hardness degrees, 50° for standard FPS and BB weights and 80° for heavy BBs (0.32g+) and DMR FPS levels. The Solid Edition differs from the Hollow Edition in its solid form which prevents the tensioner from deforming when used with heavy BBs travelling at high velocity. The inner surface of the OHM is also concave, making it the perfect pairing for Maple Leaf buckings with concave contact patches.

Whether you're working on a DMR build or accurising your primary AEG, the Maple Leaf OHM Silicone AEG HOP-Up Tensioner; Solid Edition will give you the performance you need!

If you have HOP-up woes with your SMG-5 this could be what you need to fix it up! The CYMA HOP-Up Chamber with Rubber and Nub for SMG-5 AEG is a replacement original part for the CM.027 SMG-5 series but should also work in any TM based SMG-5 AEG (not NGRS variants). The set includes a complete HOP-up unit with the HOP-up arm and also includes a basic HOP-up rubber and nub, giving you everything you need to replace the entire unit in a single package. 

This set is designed for the CM.027 which is a copy of the Tokyo Marui SMG-5 AEG and should also work with similar designs but is not compatible with the Classic Army SMG-5 or the later CYMA CM.041 series SMG-5 AEGs. 

A set of pre-made R-HOP patches designed to take the stress out of r-hopping your hop-up unit. These patches are replacements for existing hop-up rubber, and are designed to be glued into the window on the barrel rather than sliding over it. This modification is for advanced Airsoft tech, and requires existing r-hop knowledge or experience.

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!

If you're running one of the newer G&G platforms with the G&G rotary HOP-up, check this out! The Airtech Studios TDC Conversion Set for G&G Rotary HOP-up Unit is intended to provide maximum performance from your original G&G rotary HOP-up unit. Designed specifically for the latest G&G rotary HOP-up design, this kit includes an enhanced HOP-up arm, TDC trolley, 2 x M-nubs and a centring unit.

The benefits of a TDC HOP-up unit include a stronger HOP-up effect and less chance of side-to-side shot deviation when using heavy BBs at high FPS. This part will require modification to your original outer barrel to fit, but thankfully these mods are quite easy and thoroughly explained on the Airtech Studios website. If you want your G&G Rotary-equipped AEG to reach out and touch the enemy at crazy ranges, this TDC Conversion Set is what you need!

If you have damaged your HOP-up unit and are looking for a replacement, CYMA are now offering their original HOP-up units as an aftermarket part. This unit is for the CM.041K and CM.041PDW AEGs, but will not fit the full sized CM.041 AEGs. The unit is constructed from polymer and comes complete other than the HOP-up rubber. The HOP unit, slider, c-clip and HOP nub are all included, so if you have lost or damaged one of these bits you are in luck!

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 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. 

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!

If you're working on a beast of a sniper rifle, the Trusight TDC Conversion Kit for VSR-10 will get you there! This TDC HOP-up conversion set is a very impressive design, providing TDC functionality for reduced side-to-side deviation and a stronger HOP-up effect without requiring your outer barrel to be drilled!

That said, limited modifications to the TDC carrier are required due to purposely being made off-spec. This allows you to get the perfect fit for your specific HOP-up chamber by carefully filing it down with hand files. Installation instructions are available on the Trusight Website but for those who don't like reading, check out the video here.

The main benefits of this set over other TDC kits are it doesn't require any permanent modifications to your original VSR-10 parts and you won't need to carry an Allen key in-game or ruin the looks of your VSR with a dial on the top of the barrel as you'll be using the original slider adjuster. Compatibility-wise, this set is designed specifically for the Tokyo Marui VSR-10 series but may also fit VSR-10 clones, though extra modification may be needed for a perfect fit.

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 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!

The Airtech Studios RetroArms Rotary Centring Unit is an easy upgrade to improve your AEG's accuracy. It is constructed from high-density polymer and fits a RetroArms CNC Rotary HOP-Up Chamber Gen.2 ONLY. It prevents the hop-up unit from wobbling side to side. Once fitted, the RetroArms Rotary HOP-Up Chamber will be securely fitted in place and sit in its true centre position, which prevents BBs from swerving at a tangent when shot.

As well as removing the wobbling from your HOP-up chamber, it also provides a better air seal due to the improved tightness of the system, resulting in a more stable FPS output from your AEG. While the power upgrades for shooting BBs further are significant, they wouldn't be effective without accuracy. It's often that small parts like this are overlooked in Airsoft upgrades but they have a major impact and the Airtech Studios RetroArms Rotary Centring Unit is exactly that.

Improve the consistency and accuracy of your RetroArms CNC Rotary HOP-Up Chamber Gen.2 with a simple polymer part, the improvement will be instantly noticeable!
