Thanks to Synchronizor for this review.
Founded in 1990 by gunsmith Hans Vang, Vang Comp Systems, Inc. offers a variety of gunsmithing and refinishing services, but is perhaps best known for the system of barrel modifications that they offer for combat shotguns. The company also produces a handful of tactical shotgun parts and accessories, including a line of magazine extensions. Vang Comp’s shotgun accessories have an overall positive reputation across the shotgunning community for quality and durability, and their Remington magazine extensions, offered in +1 and +2 varieties, are popular choices for combat and defensive 870 builds. They are also notably used on Nighthawk’s extremely high-dollar custom combat 870s.
