The 28-inch carbon-steel barrel features a vent rib for quick sight alignment and factory porting to help tame recoil and muzzle rise. A single brass bead up front provides a clear, uncomplicated sight picture that many wingshooters prefer.
The matte-black aluminum-alloy receiver keeps weight down while maintaining strength. Dual action bars reinforce the pump stroke, ensuring smooth operation even under hard use.
An OD green polymer stock with a 14-inch length of pull offers weather resistance and a firm shoulder fit. A factory recoil pad softens 12-gauge kick, and the rear sling-swivel stud makes it easy to add a sling for field carry.
The 3-inch chamber handles a wide range of hunting and target loads, and the barrel is compatible with Mossberg’s Accu-Choke system for easy pattern tuning (choke tubes not included).
