The Panzer Arms M4 is a semi-automatic 12-gauge shotgun that combines tactical performance with affordability. Modeled after the renowned Benelli M4, it features an 18.5-inch barrel, 3-inch chamber, and a 5+1 capacity, making it suitable for home defense, tactical applications, and competitive shooting. The M4's inertia-driven operating system ensures reliable cycling with heavier loads, and its compatibility with Benelli M4 parts allows for customization and upgrades.
