The Remington Spartan 453, also known as the SPR 453, is a gas operated semi-automatic shotgun. It is an American import of the Russian-made Baikal MP-153,^[2] manufactured by Izhevsk Mechanical Plant in Izhevsk, Russia. It was marketed and distributed by Remington Arms, who ceased importing the shotgun to the United States in 2008.^{[citation needed]}

The SPR 453 is inexpensive compared to other semi-automatic shotguns. It is most often used for hunting birds, and for clay pigeon shooting sports, such as trap and skeet. It is chambered for 12 gauge shells, in lengths of 2+3⁄4 to 3+1⁄2 inches (7.0 to 8.9 cm).^[2] Several versions of the SPR 453 were marketed, including one using Mossy Oak "New Break-Up" camouflage.^[2]
