This phenomenal M4 semi-automatic shotgun is quickly becoming legendary for rugged reliability you can count on in the most adverse circumstances and conditions. The M4 Tactical shotgun is light, durable, fast-handling, and an exact copy of the renowned name brand M4 with the famous A.R.G.O Piston-driven semi-auto action. This action is one of the best ever developed and cycles everything from target loads to the heaviest 3-inch magnums. Rather than the traditional solid shotgun stock, this model comes with the highly popular fixed skeleton stock already factory-mounted to the firearm. Also featured on this model is an extended mag tube with sling attachment points. A rail section runs along the top of the receiver and is perfect for optics mounting. If you do not wish to mount an optic, ghost ring sights come standard.
