Airsoft Electric Parts - HOP Units, Rubbers & Parts

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 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 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 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 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 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.

If you are building an Airsoft DMR this enhanced HOP-up rubber set from Laylax Prometheus should be on your shopping list! Laylax Prometheus has a fantastic reputation for enhanced HOP-up buckings, providing the Purple bucking used in the Bolster Armouries ONYX AEG series thanks to Prommy's wealth of experience and pedigree. We love them, and we think you will too!

This bucking is designed for builds shooting at 350-400 FPS, putting it right in the sweet spot for DMRs. When installed, this set should improve range, enhance air seal and allow for heavier weights of ammo to be used. Compatibility-wise, this should fit the vast majority of Airsoft AEGs which use the standard TM AEG style HOP-up bucking/rubber and nub, which is almost all of them!

Are you having HOP-up troubles with your ARCTURUS AK platforms? This is exactly what you need! This HOP-up chamber is a complete replacement part and comes with the necessary pieces for installation.

It is an affordable solution to mend your platforms with damaged or old HOP-up chambers.

We only recommend installing this HOP-up unit if you are confident in your abilities, some parts are small and installation must be precise.

Fix your AK replica's damaged HOP-up with the ARCTURUS Rotary Hop-Up Chamber For ARCTURUS AKs and you will have your replica shooting prime and proper in no time!
