Foxtail Precision Holosun K Optic Mounting Plate Features The Foxtail Precision Optic Mounting Plate is engineered specifically for the Mossberg 500 giving the shotgun a dedicated mounting solution for optics built on the Holosun 407K or 507K footprint. Because the plate is purpose fit to the Mossberg 500 rather than a universal adapter it mounts with a consistent repeatable position that helps the optic hold zero through recoil. The anodized aluminum construction resists wear and corrosion standing up to the demands of a defensive or hunting shotgun that may see use in all weather conditions. At 5.6 inches long and only 0.5 inches tall the plate keeps the optic low and close to the bore for a natural sight picture. Finished in black to match the Mossberg 500 s factory finish the plate blends in visually rather than standing out as an aftermarket addition. Weighing just 0.11 pounds it adds virtually no perceptible weight to the shotgun preserving the handling characteristics shooters expect from their 500. This direct fitment approach simplifies installation since the plate is designed around the Mossberg 500 s receiver geometry rather than requiring extensive adjustment. The Foxtail Precision Optic Mounting Plate for the Mossberg 500 is available for sale at GrabAGun for shotgun owners who want a dependable way to run a compact red dot optic.
