  • R-HOP Kit for AEGs
  • Includes bucking & nub
  • Extend range & improve accuracy

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!

  • Replacement original parts
  • Includes HOP-up chamber, bucking and nub
  • For CYMA CM.027 SMG-5 series

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.

  • Flat HOP-up nub
  • Compatible with most Airsoft AEGs and GBBs
  • Extend your range and improve accuracy!

If you are looking for better accuracy and range, a flat HOP-up nub should do it! The Hades Airsoft Flat HOP-up nub is designed to apply a stronger HOP-up effect than standard cylindrical nubs and is available in 4mm or 5mm lengths.

The nub is constructed from 3D-printed synthetic rubber and maintains its shape regardless of any pressure applied, guaranteeing even pressure is applied across the nub and transferred to your BB without distortion. An additional advantage of using a harder synthetic rubber than the average is that performance will remain constant, even in lower temperatures.

As with other flat HOP-up modifications, this part is only recommended for those who are experienced working on HOP-ups and we suggest that you measure the window size of your inner barrel to ensure you get the correct size for your build.

  • TDC HOP-up mod set
  • Requires extensive modification
  • For VSR-10 & VSR-10 clone sniper rifles

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!
