Umbrella Armory Hop-up Chamber Assembly MaxxPro with 6.03 R-Hop Barrel 416mm

Umbrella Armory provides us with an assembly consisting of a 6.03mm Prometheus barrel modified for R-Hop, flat rubber, and MaxxPro hop-up chamber.

The Prometheus barrel with a diameter of 6.03mm is modified and features R-Hop installed to offer improved accuracy, greater distance, and higher consistency. The R-hop system is handcrafted and is the 2.0 version offered by Umbrella Armory.

The rubber used is a blue, soft Madbull brand and is manually modified. Compatibility may vary depending on the length of the air nozzle.

The hop-up chamber is made in collaboration between Umbrella Armory and Maxx Model. It is specifically built to be used with modified R-Hop barrels. The nub is flat and differs from the nub typically used in ME chambers. This nub is used to apply the correct pressure on the center of the R-hop patch. This chamber does not support flat rubber configuration and standard barrel and it is recommended to use flat rubber with modified R-Hop barrels because the hop-up adjustment wheel does not allow the arm to drop as much as in ME chamber models, in order to prevent damage to the R-Hop patch. However, these modifications allow for finer adjustment of the hop-up adjustment.
