Truglo TG-TG8955M1 Shotgun Receiver Optic Mount

The Truglo TG-TG8955M1 is a one-piece optic mount designed to attach a red-dot or similar micro optic directly to drilled and tapped Mossberg shotgun receivers. It accepts TruTec Micro optics and other optics that use a four-post mounting pattern, providing a low mounting height for sighting convenience. Installation does not require adding a Picatinny rail, and the mount ships with the necessary mounting hardware and basic tools. Its compact, lightweight profile keeps the optic close to the receiver for a streamlined setup on compatible Mossberg models.
