SUAREZ TAC-14, TAC-13 GHOST RING SIGHTS
These are the same sights found on the Benelli series of shotguns. They allow you to use them alone, or obtain a perfect cowitness with your Trijicon RMR or similar red dot.
Front sight and rear sight options and variations are available as well as installation on your weapon and refinishing your weapon.
The sights are designed to fit a Remington weapon, but will work on weapons that share the receiver and barrel contour.
