What’s Included
- Mossberg 500A All-Purpose Field 12 Gauge shotgun
- 28-inch barrel with Imp Modified Accu-Choke installed
The 28-inch steel barrel uses Mossberg’s Accu-Choke system, allowing easy choke changes without tools. Factory porting along the muzzle helps manage recoil, while the ventilated rib provides a clean sighting plane to the single brass bead.
Mossberg’s twin action bars and steel-to-steel lockup deliver smooth, dependable cycling. The 3-inch chamber accepts both 2 3/4-inch and 3-inch 12-gauge shells, giving hunters and sport shooters a wide range of load options.
The receiver is drilled and tapped at the factory and fitted with filler screws. Its black-anodized finish complements the hardwood furniture, and the gold-anodized trigger adds a subtle visual accent.
A Monte Carlo-style hardwood stock with pressed checkering offers a comfortable 14-inch length of pull, and a ventilated rubber recoil pad softens shoulder impact. The ambidextrous tang safety is intuitive for both left- and right-handed shooters.
