"Gorgeous barrel, nice finish. The hop window is rounded to reduce wear on Drop-In Buckings, but at the same time disabling the ability to attach R-HOP without filing or sanding, in which case a straight cut window is recommended. Barrel has two sets of notches to fit into the hop unit, not sure what the second set is used for, I originally assumed it's for VFC's GBBR hop up units but those also uses the standard notch positions. I suggest running this barrel with a quality drop in bucking such as the Tru-Hop or the Pommy Purple.
