Mossberg Accu-Choke 20 Gauge Modified Choke Tube

The Mossberg Accu-Choke is the factory 20 Gauge Modified choke tube designed for Mossberg shotguns fitted with ACCU-Choke threaded barrels. Built from steel with a durable black oxide finish, this choke tube handles lead, steel, and all other non-toxic shot loads with equal reliability.

The Modified pattern delivers a .020" constriction and is recommended for shots out to approximately 45 yards, producing a balanced, versatile pattern for a wide range of shooting applications. Each tube is clearly marked with its patterning designation for quick, no-guess identification in the field. The non-ported design keeps the muzzle report clean while delivering consistent, predictable patterns downrange.

This choke tube is engineered for direct fit on Mossberg 500, 505, and 510 Mini shotguns, along with Maverick 88 models featuring threaded barrels. It is also compatible with Smith & Wesson, Savage, and U.S. Repeating Arms shotguns that share the same ACCU-Choke thread pattern, providing a direct-fit replacement or pattern-change option across a wide range of popular 20 gauge shotguns.
