The Vang Comp System involves a specific set of modifications to the shotgun barrel.
- The process begins with back-boring the barrel to a slightly larger internal diameter than standard.
- After back-boring, Vang Comp applies a series of small, carefully spaced compensating ports near the muzzle. These ports direct some of the expanding gases upward, counteracting the shotgun’s natural upward rise when fired.
- By optimizing the barrel’s internal structure, the system ensures a tighter and more consistent shot pattern.
