The flat hop modification service includes Bucking Flat-Hop service, Hop-up Modification, Flat nub installation, Sorbo-Nub or M-nub. Include this service with an r-hopped barrel to make an r-hop drop-in kit assembly.

It is designed to give you an elongated flat facing mound which in turn, will give you a more consistent backspin to your bb. It is also important to use a soft flat nub material, which is why we use sorbo-nubs or m-nubs for our flat hops. Soft material nub will give you maximum consistency, while hard nubs such as the common modify, maple leaf, firefly nubs, will often amplify your inconsistencies.
