The receiver mounting scheme of the receiver mount shotgun SureShell shotshell carrier for the Mossberg 500/590/835 substitutes a steel bolt for the trigger pin retained in place by a black oxide plated acorn nut. At the front of the mounting plate, custom retaining steel hardware is used with an elongated extractor screw and a machined key hole in the plate. The mounting plate was designed not to obscure the receiver serial number to make it easier for armorers to inventory their weapons.
