California-based Mesa Tactical has introduced four-, six- and eight-shot SureShell shotshell carriers and optics rail assemblies for Mossberg's Model 500 and Model 590 pump action shotguns.
SureShell shell carrier and rail assemblies for the Mossberg pump shotguns feature four-, six- or eight-shell shotshell yokes fitted to a bracket incorporating a MIL-STD 1913 (NATO STANAG 2324) Picatinny optics rail. The rail bracket is secured to the shotgun receiver using the optics rail mounting holes already drilled and tapped into the Mossberg receiver at the factory. With most part numbers, the optics rail stretches most of the length of the shotgun receiver, or about 4½ inches, allowing the mounting of a red dot scope or other target acquisition aid.
The suggested retail price ranges from $115 to $270.
