  • Save cost on expensive aftermarket hop-up chambers for R-Hop usage
  • No need to modify the stock arm and add an M-nub, the ARA solves both issues
  • Easy drop-in installation with no modifications required
  • Achieve perfect top-down center force - give your r-hop a perfect, evenly forced pressure
Thinking of installing a R-hop set-up in your 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, our R-HOP arm is designed to be a drop-in upgrade to mitigate the risk and give a perfect, even-forced pressure.

Manufacturer: Airtech Studios


Compatibility: Compatible in all Tokyo Marui-spec M4/M16 rifles with ProWin hop up units
Material: Durable, polymer fiber-injected plastic
