Airsoft Electric Parts - Hop-Up and Parts

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!

A replacement Hop-Up Unit for Airsoft AK Rifles, designed and constructed to high standards by Action Sports Games in Denmark as part of their Ultimate Upgrade Parts Range. 

A high quality 50 Degree silicone hop rubber designed to replace the current hop rubber in you weapon. This particular hop rubber is made to be compatible with all standard AEG type barrels and hop units.

If you're looking for accuracy improvements for your M4/AR-15 AEG, the Delta Armory TRINITY R-Hop Bucking Bundle for AEG is what you need to tighten your groupings. 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 TRINITY bucking is diamond-shaped, similar to the Maple Leaf Super bucking, intended to improve accuracy by applying backspin more consistently. The advantage of using a TRINITY 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're looking for tighter groupings from your Airsoft AEG, the TRINITY R-HOP Bucking Bundle is the one to go for!

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 high quality 60 Degree silicone hop rubber designed to replace the current hop rubber in you weapon. This particular hop rubber is made to be compatible with all standard AEG type barrels and hop units.

If you're building your M4/AR-15 AEG to focus on range, accuracy and efficiency, the RetroArms CNC Rotary HOP-Up Chamber Gen.2 for M4/AR-15 AEG belongs in your build. This set is a full replacement rotary type HOP-Up unit for version 2 gearbox-equipped Airsoft M4/AR-15 platform AEGs and includes all of the parts you'll need to replace your stock HOP-up unit. The set also includes the choice of two HOP-up arms, one designed for flat HOP setups and one for conventional.

As with all internal upgrade parts, we only recommend this HOP-up unit for the technically proficient as it requires full assembly and does not include a HOP-up rubber or HOP-up nub. That said, the RetroArms CNC Rotary HOP-Up Chamber Gen.2 for M4/AR-15 AEG is widely regarded as one of the best options out there for the pros, and when set up properly, it has the potential to outrange anything else on site!

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!

Will fit almost all Airsoft AEG on the market. The rubber is made from Silicon and features a 50 Degree Nub, applying a moderate amount of hop to BBs. 

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!

Master Mods are a new Internal Parts manufacturer bringing a whole new meaning to the term reliable. The Master Mods R-Hop Contact rubber is a hardened contact for use with heavier weight BB's, increasing accuracy & performance.

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!

A high quality silicone hop rubber designed to replace the current hop rubber in you weapon. This particular hop rubber is made to be compatible with all standard AEG type barrels and hop units. 

An original hop unit only (no gears or adjsuters) for the PTS Masada AEG, this is a high quality manufactured replacement piece.

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!

Delivers more range and improved accuracy from your Arisoft AEG. Designed for primerally M4 AEGs but may be compatible with other AEGs that use an M4 style hop unit.

We have stocked this particular AEG hop rubber set for years. One of our most popular, reliable and promising items you can install into your own Airsoft hop unit. 

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.
