R-Hop is a popular modification in the Airsoft community 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 airseal 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.

"I installed this in my Ak-47 dsg that shoots 350 fps. I paired with a G&G green bucking I am able to place headshots at 200 ft.
"Easily the best upgrade for any rifle. I put one in my vfc 416, the gun is otherwise, internally stock. Came in under the fps limit for OPX milsim game, but i couldnt believe the range and accuracy! Cant shoot anything under .30's without overhopping, but I generally use at least .3's. From now on, when someone asks what should they upgrade on their guns, I'd say the rhopped barrels and dont worry about anything else!
"Amazing barrel, can reach out to 450 ft with it
