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 need more range and accuracy from your Airsoft AEG, the 4UANTUM Friction Pro High-Performance AEG HOP-up Bucking belongs inside! This cutting-edge HOP-up upgrade set includes an HOP-up rubber/bucking with a uniquely shaped contact patch and an OMEGA-style flat nub, ready to be installed into any AEG-type HOP-up unit.

The Friction Pro bucking was developed over 2 years of rigorous testing and, since its launch, has taken the Airsoft world by storm. We've been extremely impressed by the performance of this bucking during testing, offering exceptional range and a remarkably tight grouping, a combination other buckings often compromise on.

With the ability to lift up to 0.48g BBs in its stride with 60-meter accuracy when set up correctly, the Friction Pro High-Performance AEG HOP-up Bucking from 4UANTUM is ideal for any long-range AEG setup but is especially potent in a DMR build!

Are you having HOP-up troubles with your M4 platforms? Delta Armory has you covered! This HOP-up chamber is a replacement part and comes with all the necessary pieces for installation, including the HOP-up rubber and nub. The main chamber is made from a sturdy plastic polymer and is compatible with all M4 style AEGs which have V2 Gearboxes. It is an affordable solution to mend your platforms with damaged or old HOP-up chambers.

The Delta Armory HOP-up chamber is an affordable replacement for M4/AR-15 AEGs, fix up those old primaries and get them shooting again with this low-price solution.

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're after more accuracy and range from your GBB pistol, VSR sniper rifle or GBBR, the 4UANTUM Friction Pro High-Performance VSR/GBB HOP-up Bucking is the key! This cutting-edge HOP-up upgrade set includes an HOP-up rubber/bucking with a uniquely shaped contact patch and an OMEGA-style flat nub, ready to be installed into any VSR sniper rifle, GBB pistol or VSR/GBB compatible GBBR HOP-up unit.

The Friction Pro bucking was developed over 2 years of rigorous testing and, since its launch, has taken the Airsoft world by storm. We've been extremely impressed by the performance of this bucking during testing, offering exceptional range and a remarkably tight grouping, a combination other buckings often compromise on.

Designed to perfectly centre your BB with each shot and lift up to 0.48g heavy-weight BBs, the Friction Pro provides positively epic long-range performance and is ideal for accuracy-focussed skirmishers who want impressive range without a wider grouping. Whether you're running low-capacity GBBR mags and need to make every shot count or you need your pistol to reach out and surprise the enemy team, the 4UANTUM Friction Pro High-Performance VSR/GBB HOP-up Bucking is what you need!

If you seek more accuracy and range from your AEG, the Prometheus Bridge HOP-up Tensioner for AEGs will help you achieve it! Supplied as a pack of two tensioners, these are the "Bridge" style design with a central groove designed to reduce side-to-side deviation, focussing on maximum accuracy and providing the smallest grouping possible. The contact surface provided by this HOP-up nub (another word for tensioner) is far larger than the standard, resulting in a stronger backspin effect and extended range with heavy-weight BBs. 

The two tensioners included in the set are of different colours; one purple and one black. The purple tensioner is made from softer rubber, designed for sub-350 FPS builds and the black one is slightly harder, ideal for 350 FPS and above, making it the perfect tensioner for an AEG DMR. Compatibility-wise, these tensioners should fit almost any Airsoft AEG HOP-up unit but as always is the case with internal upgrades, we only recommend these for experienced techs and those who know their way around AEG internals. If accuracy and range is your objective, the Prometheus Bridge HOP-up Tensioner for AEGs belongs in your build!

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!

Designed specifically for the Gate EON CNC Rotary HOP-up chamber, the Airtech Studios Full Upgrade Set for Gate EON HOP-up Chamber includes a TDC trolley, 2 x M-nubs and an inner barrel centring unit. This set is designed to convert the Gate EON into a true TDC unit, giving you more range and accuracy than ever before!

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 a certain amount of expertise to install but thankfully, the process is fully explained on the Airtech Studios website. If you want to get the most out of your Gate EON HOP-up chamber, this kit will do the trick!

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!

Turn your stock ASG Scorpion EVO's HOP-up chamber to a TDC design without having to replace the whole unit. This kit includes everything you need to install the system into your current HOP-up chamber. It is compatible ONLY with ASG Scorpion EVOs and will not fit in any other HOP-up systems.

TDC (Top-Down-Centre) HOP units are incredibly sought after due to the increased friction they add to BBs, which increases the effectiveness of the HOP applied to your BBs. By installing TDC to the stock HOP-up you are guaranteed compatibility with the platform.

The set also includes rubber nubs, these ensure the HOP is stable while BBs accelerate through the unit, further improving the performance and consistency of your ASG Scorpion EVO. This is a very complex installation process and we only recommend it if you are confident in your understanding and ability to fit it to your HOP-up chamber.

If you are looking to upgrade your HOP unit, in most cases these days there isn't much to gain if you already have a rotary unit in your gun. This is the exception! Krytac has taken the rotary HOP unit and added in audible and tactile clicks when you adjust, locking the unit in its set position and allowing you to adjust accurately even in low light conditions! The unit also has engraved numerical setting indicators around the adjuster, allowing you to keep track of which setting works best with which BB weight, avoiding the trail and error! This package also includes a KRYTAC HOP rubber.

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.

Compared to the Autobot, this hop up rubber is far stronger and has a flatter shaped contact patch inside. 

A 50 degree hop rubber for VSRs and unbridged barrels, designed to maximise range at a slight cost to accuracy. 

If you want to push your VSR-10-based sniper rifle to the absolute pinnacle of accuracy, a TDC mod should do the trick! The Hades Airsoft TDC HOP-up Unit Set for VSR-10 Sniper Rifle is designed to replace the original HOP-up arm and adjuster, providing direct pressure to the top of the HOP-up nub and bucking to eliminate side-to-side shot deviation.

Installing this TDC unit will require some extensive, irreversible modifications to your base sniper rifle, so we only recommend this set for those who are confident with power tools and have a decent level of Airsoft technical knowledge.

The unit requires you to drill a hole through the top of your outer barrel using either a 5mm or 5.5mm drill bit and the included drill guide, inserting the guide into the stripped outer barrel to ensure the hole is drilled in the right place. Hades also recommends that when the modification is complete, that you glue the TDC unit to your outer barrel using super glue or another strong adhesive.

If you are the type of sniper that likes to get their hands dirty with modifications and you want your VSR to outrange and outshoot the rest, this kit will do it!
