Combination stackable magazine cores and outer binding skins for changing style and capacity versability of a firearm and further including dual use follower

Abstract

A combination magazine and outer skin for a firearm including a magazine core adapted to releasably engage a firearm in communication with an action assembly associated with the firearm. Multiple cores are stackable end-to-end to define a continuous interior, with an end cap engaging an open bottom of a lowermost core. A design indicia exhibits an interior recess and is assembled around the stacked cores. A dual use follower is in use with an uppermost located magazine and maintains the assembly bolt in an open position and following the last cartridge being fired until such time as the magazine is removed. In the further variant, with a BHOA installed in place, the follower activates the BHOA and the bolt to remain in the retracted/open position, following magazine removal.
