Abstract: The invention relates to a capacity limiting assembly that provides substantially irreversible alteration of a box magazine to limit its cartridge capacity wherein the box magazine comprises a magazine housing having a vertical dimension YM, a magazine spring having at least 1 coil, and a follower. The assembly includes a limiter body and a lock plate. The limiter body has a top edge engageable with a bottom surface of the follower that is operatively associated with a top of the magazine spring extending into the cartridge reservoir and is configured to be disposed substantially within the at least one coil of the magazine spring. The limiter has a vertical dimension YL that is less than the vertical dimension YM of the magazine housing, and a limiter bottom edge that is engageable to a lock plate.

Abstract: A molecular nanotag is disclosed that includes a core nanoparticle with a diameter of less than about 100 nm, with an optional shell surrounding the core, and an armor bound to the surface of the core nanoparticle, or if present, to the surface of the shell. The molecular nanotag also includes a functionalized end with a fixed number of binding sites that can selectively bind to a molecular targeting ligand. Any one of, or any combination of, the core, the shell and the armor contribute to fluorescence, light scattering and/or ligand binding properties of the molecular tag that are detectable by microscopy or in a devices that measures intensity or power of fluorescence and light scattering.
