Airsoft Hop Up Units & Buckings

Whether your HOP-up rubber is worn out or you are seeking an upgrade, the Novritsch HOP-up Bucking for SSP1/SSP5 GBB pistol is one to keep an eye on. This HOP-up bucking is a big reason that Novritsch pistols have such incredible range, and being a VSR/GBB style HOP-up rubber, this should be compatible with most TM-based GBB pistol designs as well as the VSR-10 sniper rifle 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. 

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.

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. 

Compared to the Autobot, this hop up rubber is far stronger and has a flatter shaped contact patch inside.
