  • 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!

  • Wide Flat Patch
  • 50 Degees Of Hardness

  • 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!

  • 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.

  • R-HOP Kit - Great for heavy BBs
  • Includes bucking, HOP arm & nub
  • 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!

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!

  • Set of two MEC rubbers
  • 60 & 70 Degree rubbers included

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!

  • Enlarged contact surface
  • Bridge style - Great for accuracy
  • Fits most Airsoft AEG HOP-up units

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!
