Cooper Firearms of Montana Model 21 Classic .223 Rem w/ Options. Cooper has allowed us to add a few options to the Classic. We did this one in .223 Rem., w/ Exhibition Claro walnut that we acquird ourselves from one of the nation's most respected wood purveyors. The swivels are inlayed, it has a skeleton grip cap, and a matte finish 24" fluted barrel, as well as being factory engraved in a floral pattern on the receiver, on the bbl., trigger bow, and screws. A Gulf Breeze Exclusive...and a gun you can't get out of the catalog.
