Mossberg Accu Choke Full Choke Tube for 20 ga Mossberg 500/505/510

The Mossberg Accu Choke Full Choke Tube for 20 ga Mossberg 500/505/510 is a precision interchangeable choke system designed for shooters and law enforcement professionals who demand tight, consistent shot patterns at extended range. Built by Mossberg & Sons Inc., this full choke tube fits threaded barrels on Mossberg's flagship 500 series platform—one of the most fielded pump-action shotguns in North America. Full choke geometry concentrates pellet spread over greater distances, making it ideal for waterfowl hunting, competitive clay sports, and tactical applications where standoff distance and precision matter.

This choke tube works by progressively constricting the shot column as it exits the barrel, maintaining pellet density and reducing spread at 40+ yards compared to more open chokes. The full constriction provides approximately 70–75% pellet retention in a 30-inch circle at 40 yards, delivering superior downrange performance and energy retention. Engineered to OEM specifications, the tube seats securely in any threaded choke port and features the signature Mossberg Accu-Choke design for repeatable, tool-free installation and removal. Cross-compatibility extends to Smith & Wesson, Savage, Winchester (Win-Choke), and Browning Invector-pattern barrels, making it a versatile addition to any tactical or hunting shotgun setup.

Law enforcement instructors and military armorer communities rely on full choke tubes when training long-distance shotgun marksmanship or when department specifications demand tighter patterns for barrier-blind scenarios. Civilian shooters benefit from the ability to swap chokes between hunting applications and tactical ranges without purchasing multiple barrels. Compatible with Mossberg 500, 505, 510, Mini, and Maverick 88 models equipped with threaded chokes, this tube installs in seconds and requires no special tools—a critical advantage in the field or during rapid weapon transitions. Verify your barrel threading before purchase to ensure proper fit and performance.
