The Details:

Thinking of installing an R-hop set-up to your RIF? 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 to give a perfect, even forced pressure.

Features

• Save cost on expensive aftermarket hop-up chambers for R-hop usage
• No need for modifying the stock arm and adding M-nub (our arm provides both)
• Easy drop-in with no modifications required.
• Made from tough fiber polymer injected plastic
