Each receiver includes the left and right sides. These receivers are new, but old stock. They’ll fit most Crosman 761 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 761 XL, this will NOT work for your gun.
They may have minor blemishes and most have some oxidation giving them more of a brassy look as opposed to gold. They’ve never been used, but they’re old.
