The Remington SPR 453 (also known as the Remington Spartan 453) is a gas-operated, semi-automatic 12-gauge shotgun with a brief but notable history. Introduced in 2006 and discontinued just two years later in 2008, the SPR 453 represents a unique era when Remington Arms partnered with a foreign manufacturer to capture the budget-tier waterfowl and sport shooting markets.
