  • 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!

  • R-HOP Kit - Improves accuracy
  • Includes bucking, HOP arm & nub
  • Ideal for any accurised AEG build

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!

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.

  • Ideal for AEG DMR builds

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!
