The Burris SpeedBead Universal Vent Rib Mount is a no-drill, no-tap mounting solution that lets shotgun owners add a Burris FastFire red dot for faster, more confident target acquisition on clays, waterfowl, upland birds, and turkeys. It clamps directly onto the shotgun's existing vent rib and includes rib adapters to fit a range of rib widths, so it works across most shotgun platforms without any gunsmithing. The mount provides full-length, side-to-side rib capture, keeping the red dot perfectly centered over the bore with zero play once installed. Constructed from black anodized aluminum, it won't mar or damage the finish of the host shotgun, and its low profile keeps the added optic close to the natural sighting plane shooters are already used to. Backed by Burris's unconditional Forever Warranty, this mount is an affordable, reversible way to modernize a favorite shotgun with red dot capability without committing to a permanent rib modification.
