Impact Weapons Components is a company known for high quality light mounts including these two purpose built light mounts for the Benelli M4 shotgun. Available in either a 1913 Picatinny version for mounting of rail mount type weapons lights, or model that specifically mates up with Surefire Scout weapons lights.
