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.
Umbrella Armory has long been an industry leader in the modification and installation of R-Hop barrels Countless hours are spent by their staff of top notch technicians modifying each barrel, ensuring proper fitment, sizing and performance. Evike.com is happy to collaborate with Umbrella Armory to bring easy to install R-hop barrels to the market.

"Amazing barrel, can reach out to 450 ft with it
"Just put one of these in my stock Krytac trident SPR, and it easily increased my effective range (9out of 10 hits on torso sized target) from 150ft to about 180ft. it also increased my effective range by a noticeable amount, and while i have not measured the distance directly it appears to be reaching well beyond 200ft. the R hop paired with a flat hop bucking gives a noticeable improvement to the feeling of consistency, over the stock hop. Though i have put no more than 50 rounds through this barrel at the time of writing this, I can already say that I would recommend these barrels to anyone looking for consistency in their play.
"Very consistent using a Modify flat bucking and a custom eraser M-Nub. Using .30s I was getting hits in the 240-260 foot range. You MUST use heavy BBs to get the range you want/need. Transitioning to .32s.
Performs excellently out of the box, but must be constantly cleaned (I play in the desert). After a few hundred rounds, it kinda "settles" and gets just a smidgen inconsistent, but you can still get the same range and accuracy.
