Each receiver includes the left and right sides. These receivers are new, but old stock. They’ll fit most Crosman 760 XL airguns that have a brass bolt and are hammer drop (you have to cock it). If you have a self cocking variation of the 760 XL, this will NOT work for your gun.
They may have minor blemishes and tiny bits of oxidation. They’ve never been used, but they’re old.
