Description
The Mossberg 500 Security Barrel is a factory OEM 18.5″ replacement barrel designed for the legendary Mossberg 500 pump-action shotgun line. Chambered for 12 Gauge with a 3″ chamber, this barrel handles both 2-3/4″ and 3″ shells, giving it real versatility for everything from clays and upland loads to heavy buckshot and slug defensive rounds.
Built around a cylinder bore, the barrel delivers a wide, unobstructed shot pattern that makes it ideal for short-range defensive and tactical applications. A traditional bead front sight provides a simple, snag-free aiming reference, and the matte blued finish reduces glare while standing up to field use.
This 6-shot configuration barrel is a direct fit for the Mossberg 500 and Maverick 88 6-shot model shotguns, making it an easy way to swap a longer hunting barrel for a compact, home-defense-oriented security setup. Whether you’re replacing a worn factory barrel, building out a dedicated defensive shotgun, or keeping a spare on hand, this genuine Mossberg 500 barrel brings the proven reliability of the 500 platform to your safe.
