The ATA Arms ETRO10 is purpose built as a tactical defense shotgun from muzzle to butt stock. An extended cylinder choke ships with the ETRO10 but it can be removed and replaced by a choke of your choosing. An elevated front sight tops the barrel and an adjustable rear sight and Picatinny rail are mounted on the receiver. Red dots and optics can be mounted to the top rail, while the rail under the forend is perfect for lights or lasers. A fixed pistol grip stock with a rubber recoil pad provides excellent control and comfort while shooting.
