A receptacle for firearms that comprises a primary receiving cavity for a firearm that is considered to be semi-universal and has multifunctional capabilities. This primary receptacle allows the user to adjust the receiving cavity to fit a plethora of sizes, styles, and calibers within a certain model line. This is accomplished by a series of dual adjustment springs and molded stops that function together to customize tension and squeeze within the receptacle. The compact and ergonomic design allows the receptacle to be easily interchangeable among a variety of carriage or mounting apparatuses.
