Considering adding an R-hop setup to your airsoft gun? Our R-HOP arm is a drop-in upgrade that eliminates the need for cutting or sanding your stock hop-up arm, reducing the risk of unbalanced force on the R-hop patch and ensuring even pressure.

Features:

  • Avoid the expense of aftermarket hop-up chambers designed for R-hop.
  • Eliminates the need to modify the stock arm or add an M-nub (our arm includes both).
  • Simple drop-in installation without any modifications.
  • Constructed from durable fiber polymer injected plastic.
