Product Description
Airtech Studios Advanced R-Hop Arm & M-Nub for KWA Rotary Hop Units
Thinking of installing an R-Hop set-up on your KWA rifle? Instead of modifying your stock ARM by cutting /sanding which may run the risk of an unbalanced force pressing on the R-hop patch - their R-HOP arm is designed to be a drop-in upgrade to mitigate the risk to give a perfect, TDC (top-down-centre) evenly forced pressure.
They were inspired by the self-leveling nub feature found on the Maxx brands for the Silverback SRS hop-up and wanted to bring ideas to the KWA rotary platform.
- TDC Top-down-centre force applied evenly on the R-Hop patch.
- No need for modifying the stock arm and adding M-nub (our arm provides both!)
- Easy drop-in with no modifications required.
- M-nub provides an even distribution of force applied across the whole surface of the R-Hop patch.
- Tough Polycarbonate Construction.
