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.

WHAT IS R-HOP?

R-Hop is a popular modification in the Airsoft market in which a high-density rubber patch is installed in the hop-up window and then polished flat on the inside of the barrel to ensure perfect fitment. R-Hop improves the consistency of each consecutive shot, improves peak backspin and air seal, and provides the user with higher tolerances to imperfections in the projectile. All of these features combine to offer the Airsofter a higher-performing Airsoft weapon.
