For optimum performance an R-hop setup should be used with high quality BBs, a good compression system, inner barrel stabilization and a clean barrel.

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.

Advanced Locking Ring
The advanced locking ring is designed to be used with AEG Hop Up Units to improve consistency and accuracy.

The brass ring which sits between the end of the hop unit and inner barrel tends to leave a gap which allows the barrel to be tilted at an angle.

This improved design replaces the stock O-ring (normally brass) at the end of setting up the hop unit.

Once the new O-ring is installed, it will ensure a snug fit to restrict the motion of the barrel within the hop-up chamber. It will secure the inner barrel in the true horizontal position. Even when shots are fired, which is the moment where there is the most stress and vibration at the hop-up, the O-ring will ensure the structure is intact.

This creates a dependable system for the BB to travel down the barrel undisturbed for the most consistent and accurate shots.

The end of the locking ring is extended to give a longer locking surface to shim the inner barrel against the inside of the hop chamber. Silicone o-rings are included to give a tight fit with the lower receiver and further restrict movement and vibration when shooting.

Installation notes
If the ring is a too tight for your inner barrel, lightly sand the inside of the ring and test fit in small increments until a snug fit is achieved.

Compatibility
Most AK74/RK74 type AEGs
