Features of the Mossberg 500 Rolling Thunder include the venerable 500 pump-action 12-gauge shotgun, which serves as the basic platform for more sporting, home defense, tactical and military shotguns. This model features a 23-inch cylinder-bore barrel with a three-inch chamber and brass bead front sight. Additional features are a barrel heat-sheild and a solid aluminum, ported muzzle stabilizer, which reduces recoil and muzzle jump but drilled and tapped to accept the Mossber picatinny rail system. The Rolling Thunder's short overall length and light, 6 3/4 pounds, weight combine to make for easy handling and fast swinging needed for defense situations in tight places.
