The Rock Island All Generations 12 gauge is a pump-action shotgun with a 28-inch barrel from Rock Island Armory, built around a lightweight aluminum receiver (brand part no. PA12H28). The stock is the headline feature: it comes with spacers and an adjustable cheek rest, so one shotgun can be set up for shooters of different sizes. A 3-inch chamber and a 5+1 capacity make it a practical field gun, and the Full, Modified and Improved Cylinder choke tubes let you change the pattern to suit the job. It suits hunting, recreational shooting and home defense.

Key Specifications

• Chambering is 12 gauge with a 3-inch chamber, the standard bore for a general-purpose pump gun.
• The action is pump, a simple manual cycle that handles whatever shells you feed it.
• Barrel length is 28 inches, a long sight radius that smooths out the swing on birds and clays.
• Capacity is 5+1, enough shells for a field day without reloading constantly.
• Three choke tubes ship with it: Full, Modified and Improved Cylinder, so you can tighten or open the pattern without buying extras.

• The finish is black anodized, a durable, low-glare surface for field use.
• The front sight is a bead, the traditional shotgun sight for quick, instinctive pointing.
