Thinking of installing a 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

SIMPLE INSTALL – GREAT RESULTS

PERFECT TOP-DOWN CENTRE (TDC) FORCE

For R-hop to function perfectly, the patch, arm, and barrel is only one part of accuracy, using high-quality ammo, a good compression system, Inner barrel stabilization and keeping the barrel clean are also important parts of the total ultimate accuracy equation.
