The R-Hop is the true next-generation hop-up system.
When installed correctly it provides a much longer contact area to impart backspin on the bb. This results in a much greater amount of potential backspin which in turn allows you to effectively use much heavier ammo.
Due to the law of the conservation of momentum, the heavier ammo - if an equivalent amount of backspin can be applied - will travel further than lighter ammo in almost every build.

The end result is a system that can float bbs to much greater ranges with much greater accuracy and consistency than traditional hop systems are able to.

Contrary to popular accounts, the R-Hop is fully adjustable once installed however care should be taken when adjusting the system as it is possible to apply too much hop and jam the ammo in the chamber.
This can be prevented from happening but it may limit the maximum usable weight of ammo.

A typical result when paired with a 285mm 6.02 EdGI inner barrel in a platform that gives 1-1.1J or 350fps with 0.2g bbs, firing Valkyrie 0.32g BBs, is an effective range of 65-70m metres accurate to approximately 1m square with a max range of around 80m.

The R-Hop can be tuned to work for lighter ammo on request - 0.25g - 0.28g - but to see the real benefits it is recommended that you use the heaviest ammo you can afford.

The current recommended minimum ammo weight and brand for all R-Hop installations is Valkyrie 0.32g BBs



  • The R-Hop patch most suited to your gun

  • A custom made, elongated flat nub to provide even pressure along the full length of the R-Hop

  • All necessary modifications to the hop unit and bucking




The cost of the R-Hop installation is all-inclusive for a standard aeg with a compatible barrel. There is no extra labour charge for installing the R-Hop in a standard aeg.

Please note that I do not provide R-Hop installations for TNT and ultra widebore barrels (6.10mm+)

What I Do:


  • Install the R-Hop patch in the hop window of the selected inner barrel

  • Make all necessary modifications to the bucking and hop arm

  • Create a custom made, elongated flat nub to fit in the hop chamber to apply the most effective downward pressure along the length of the R-Hop

  • Rebuild the system and install the unit back into the parent platform

  • Take the gun through a comprehensive field test at a local airsoft site to ensure the system is fully operational and performing as expected. Any fine-tuning will be carried out on-site before further testing.At least four hundred rounds will be shot through any R-Hop platform capable of full automatic fire and at least two magazines on any platform only capable of semi automatic or bolt action fire.Please note, this is an essential step. The R-Hop is a hand tuned product therefore minor differences between installations will occur. It can however add up to two weeks on to the turnaround time. I do not recommend skipping the testing stage. If this stage is skipped there is no guarantee the R-Hop will perform flawlessly and any further tuning will be charged at the standard hourly rate.

  • One months after-care is included with the R-Hop installation. Assuming the testing procedure has not been skipped, any subsequent fine-tuning will be free of charge within this period. Please note that return shipping is not included in this price.

What You Must Do:


  • When adjusting the Hop you MUST always turn the hop to the lowest setting and increase in small increments until the desired effect is achieved.Turning the hop all the way on with the R-Hop installed is almost never needed and can apply too much hop. This can cause jams and other undesirable effects and any damage occurring from this will not be covered under warranty.

  • Only high quality ammo, heavy weight ammo may be used.Unless otherwise agreed, the R-Hop is not intended or warrantied for use with lightweight ammo: ie. lighter than 0.30g Ammo 
    We recommend only Valkyrie, GEOFFs, Longbow, Tokyo Marui, G&G, Airsoft Surgeon, Maruzen & Excel ammo.
