Mesa Tactical offers three receiver mount SureShell shotshell carriers for Benelli’s M1 and M2 tactical shotguns. The side mount version designed for the Benelli M1 can be installed without drilling and tapping holes in the top of the receiver. In addition, this shell carrier omits the Picatinny rail, thereby reducing the cost. The shell carrier also works on the Benelli M2, providing a shell carrier for customers who do not want a Picatinny rail.
