Product DescriptionThe Hiviz MPB-TAC is a versatile snap-on front sight designed for plain-barrel shotguns. Built around an overmolded steel spring body, it securely clamps to the barrel and self-centers behind the existing front bead for fast, precise alignment. Installation and removal are tool-free, and unique cutouts allow clearance for extended magazine clamps. The enclosed, interchangeable LitePipe provides bright fiber-optic aiming without obstructing your target. Fits most 12-gauge plain barrels without ventilated ribs.
