The Birdbuster Magnetic front sight from HIVIZ provides you a choice of sighting options for your shotgun. Installation is as simple as dropping it onto the rib, with high strength magnets to hold it in place under the harshest recoil.
The fiber optic LitePipes come both round and triangular, in red and green.
The kit comes with two red and two green fiber optics (1 each triangular and round). It includes a clear carrying case and three magnetic sight frames to fit ventilated ribs from 1/4 inch to 3/8 inch wide.
