Mesa Tactical SureShell Aluminum Shotshell Carriers with Rail combine a shell carrier with a MIL-STD-1913 (NATO STANAG 4694) Picatinny rail that accepts optical, sights, lasers or accessories. These shotshell carrier/rail systems mounts by using the drilled and tapped holes on top of the shotgun’s receiver.
Mesa Tactical SureShell Aluminum Shotshell Carriers with Rail combine a shell carrier with a MIL-STD-1913 (NATO STANAG 4694) Picatinny rail that accepts optical, sights, lasers or accessories. These shotshell carrier/rail systems mount via a “saddle” style method (Remington shotguns) or by using the drilled and tapped holes on top of the shotgun’s receiver.
SureShell Aluminum Shotshell Carriers with Rail are machined from 6061-T6 aluminum and use Mesa Tactical’s innovative rubber friction retention system to firmly and reliable hold shells in place until needed. Four, six and eight shell configurations and multiple rail lengths available.
The Integrated Rail SureShell shotshell carrier design for the Benelli M2 Tactical, Benelli M4/M1014, Benelli SuperNova and Mossberg 500/590 platforms is radically different from the side mount designs. Instead of a stamped backing plate, the shell carrier yoke is attached to a machined bracket with an integral Picatinny (MIL-STD 1913) sight rail.
The design allows the ShotShell assembly to be installed on the top of the shotgun by taking advantage of the factory tapped Picatinny (MIL-STD 1913) rail holes.
With the Benelli shotguns, the shell carrier assembly is mounted directly onto the shotgun receiver. With the Mossberg platforms, a steel mounting cleat is first installed and the shell carrier is fastened to the cleat.
Many customers will purchase SureShell carriers with rails for Benelli M1 shotguns that have not been drilled and tapped at the factory for an optics rail, but which will be drilled and tapped at home or by a gunsmith.
We recommend this work be performed only on those shotguns that are fully radiused at the top of the receivers (ie, they do not have a flat running down the top of the receiver). This is because the flat reduces number of threads that the mounting screws will be able to engage, and thus could reduce the reliability of the mount. It is also best that the work be performed by an experienced gunsmith who has the necessary tools and skills to do a proper job.
The mounting screws for the Benelli M1, Benelli M2 Tactical and Benelli M4 SureShell carriers with rails are patterned on the factory screws for the Benelli M4’s optics rail. These use an unusual #8-40 thread.
The Benelli M4 and Benelli SuperNova have different hole patterns; the Benelli SuperNova uses a different fastener.
