6.03 mm R-Hop Precision Barrel - 155 mm
Prometheus 6.03 mm is a series of top precision barrels made of stainless steel that were taken by Umbrella Armory and subjected to modifications that adapt them to R-Hop system. Every piece was individually altered by the members of Umbrella Armory team.
ATTENTION: the barrel mount requires the use of an appropriate Flat-Hop bucking as well as a chamber with M-Nub spacer.
