Advanced M4 Standard Chamber R-HOP Arm & M-nub

Thinking of installing an R-Hop set-up on your rifle? 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, TDC (top-down-centre) evenly forced pressure.

We were inspired by the self-leveling nub feature found on the Maxx brands for the Silverback SRS hop-up and wanted to bring ideas to the M4 platform. 

Features

- Perfect Self-Levelling TDC Top-down-centre force applied evenly on the R-Hop patch.
- No need for modifying the stock arm and adding M-nub (our arm provides both!)
- Easy drop-in with no modifications required.
- M-nub provides an even distribution of force applied across the whole surface of the R-Hop patch.
- Tough Polycarbonate Construction.
- Compatible on all M4 original type "3 Gear" hop-up unit chambers.

PERFECT TOP-DOWN CENTRE (TDC) FORCE

For R-hop to function perfectly, the patch, arm, and barrel are 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.

ACCURACY OVER DISTANCES - DOMINATE THE FIELD

R-HOP has the unique advantage to propel the BBs over a longer distance compared to a traditional standard hop-up. Better yet, accuracy and consistency are maintained also.

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.
