Umbrella Armory Hop-up Chamber Assembly MaxxPro with 6.03 R-Hop Barrel 363mm

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

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

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

The hop-up chamber is made as a result of collaboration between Umbrella Armory and Maxx Model. It is specifically designed 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 barrels, 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.
