Use 16 inches when you compare size with other SIG Sauer rifles, because barrel length is one of the fields that changes between similar model numbers. The plus-one capacity figure is a magazine count plus a chambered round, which is different from a listing that quotes the magazine alone. The flat dark earth cerakote finish is the surface treatment to match if you are comparing color or coating with another SIG Sauer configuration of the same model.

The model name to compare is MCX Spear-LT IR. A close SIG Sauer model can differ in finish, capacity, barrel, sights, or included parts, and those differences are the reason this page stays with this configuration.
