Airsoft Electric Parts - HOP Units, Rubbers & Parts

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 use heavy BBs and really want to send 'em, the Maple Leaf MR HOP Bucking for AEG 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, the MR HOP is designed to fit most Airsoft AEGs but as always, a certain level of expertise and tuning will be required for installation. If you're committed to long-range leaning and want your primary performing at its best, the Maple Leaf MR HOP Bucking for AEG is essential!

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 working on the ultimate AK AEG build, the RetroArms Precision CNC HOP-Up Chamber for AK AEGs is an integral part! This CNC machined HOP-up unit is made from 7075 Aluminium, granting it steel-like strength and flawlessly precise machining with the weight reduction perks of aluminium. 

The most unique aspect of this HOP-up unit is the inclusion of what RetroArms call the "collet nut", a threaded nut which seals the gap between the inner barrel and HOP-up chamber walls. This saves you any messing around with PTFE tape and ensures your platform's air-seal is perfect, resulting in more consistent FPS readings translating to improved accuracy downrange. 

The set includes everything you'll need to complete the HOP-up unit with the exception of the bucking, nub and inner barrel but will require assembly. As such, we only recommend this HOP-up unit to those confident working on Airsoft internals. Best used with the RetroArms CNC Version 3 Gearbox but compatible with almost every TM-based AK AEG on the market, the RetroArms Precision CNC HOP-Up Chamber for AK AEGs is a fantastic upgrade option for performance-oriented AK build!

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!

A soft Hop Rubber for Marui compatible AEGs offering an air-tight design, which comes supplied with a nub and is a purple colour.

Whether you're building a DMR or simply want more range from your standard AEG, an R-HOP kit can make all the difference. Unlike other R-HOP kits on the market, the Trusight Tru-Hop Gen.3 is designed to be effectively a drop-in installation, with no need for adding patches of various sizes and includes both the HOP-up bucking and a concave HOP-up nub.

The set is designed to be widely compatible and should fit most Airsoft AEG spec inner barrels, though due to its enlarged contact patch, it will only work with inner barrels with a window measuring approximately 5mm in length x 1.7mm in depth. If you are happy to get stuck in with your AEG internals and you're looking for range and accuracy improvements, the Trusight Tru-Hop Gen.3 Hop-Up Rubber is what you need!

If you are building out your M4/AR15 AEG for maximum performance the Gate EON HOP-up unit is probably already on your list! This precise HOP-up unit is constructed from CNC machined aluminium and is a rotary style unit which applies pressure directly to the top of the HOP-up rubber/nub to minimise side-to-side deviation.

This unit is compatible with M4/AR15 AEGs and can also be used with HPA setups thanks to the included nozzle sleeve which perfectly centres the nozzle for maximum efficiency.

If you're building a DMR or accurised AEG, the Delta Armory BERSERKER R-Hop Bucking Bundle for AEG is what you need to achieve maximum range. This set includes an enhanced HOP-up arm, HOP-up bucking and OMEGA-style nub manufactured for Delta by upgrade legends Psionic Upgrades. The included HOP-up arm is designed for M4/AR-15 AEG rotary HOP-up units, specifically the Delta Armory/Specna Arms/Evolution/Lancer Tactical type but the bucking and nub are compatible with other Airsoft AEGs of all different shapes and sizes. 

The inner patch of the BERSERKER bucking is shaped to fill the HOP-up window on your barrel, just like home-brewed R-HOP setups of old. The advantage of using a BERSERKER set rather than doing all the mods yourself is its simple drop-in installation, low price compared to sourcing a separate bucking, nub and HOP-up arm and guaranteed compatibility, meaning no chance your nub doesn't work with your chosen bucking. If you use heavy BBs and need a range increase, this set will do exactly that!

If you seek more accuracy and range from your AEG, a HOP-up upgrade is the first place to start! The PTS Syndicate MEC HOP-Up Bucking for AEGs; Twin Pack includes a black HOP-up rubber and a purple one, equipped with a bridge-style contact patch to minimise side-to-side deviation and maximise accuracy. 

The black HOP-up rubber is designed for 295-360 FPS builds, being made from 60-degree hardness rubber and the purple 70-degree rubber is intended for high FPS DMR builds hitting out at 360-460 FPS on a 0.2g BB. If you're the techy type with a build on the go at all times, the PTS MEC HOP-Up Bucking for AEGs; Twin Pack is a great set to have in the toolbox!

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!
