Panzer Arms M4: This phenomenal M4 semiautomatic 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, fasthandling, and an exact copy of the Benelli M4 with the famous A.R.G.O Pistondriven semiauto action. This action is one of the best ever developed and cycles everything from target loads to the heaviest 3inch magnums. Rather than the traditional solid shotgun stock, this model comes with the highly popular fixed skeleton stock already factorymounted 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. The robust tactical design and legendary reliability of the action make this a musthave shotgun.

The Benelli M4 is a fantastic weapon system produced by Italian firearms manufacturer Benelli. It was developed for a USA semi auto shotgun request for the military. The Benelli M4 is now one of the most commonly used shotguns in Military and Law Enforcement. This was the first gas operated shotgun Benelli designed, having traditionally used an inertia driven system in the semi automatics. The Auto Regulating Gas Operating, or ARGO for short, is a self adjusting, self cleaning system that allows both light field loads and heavy buckshot/slugs to be used and reliably run interchangeably without any adjustments to the shotguns gas system.
