The GForce Arms Gatlander is the hard hitting defender that is ready for anything and everything. We are excited to add this to the GForce lineup as our first inertia driven shotgun. The inertia system offers an incredibly soft recoiling and smooth cycling firearm. - With a lightning fast inertia driven action the Gatlander ensures you will be able to throw lead down range quickly accurately and effectively. - The Gatlander is a 12-gauge semi-auto shotgun sporting an 18-inch barrel. It is chambered for 2 3/4- and 3-inch shotshells with a 5+1 capacity.
