Panzer Arms M4 Tactical Semi-Automatic Shotgun 18.5" Barrel 12GA 3" 5 Round - Piston Driven - W / Walnut Stock - Disruptive Gray - PAM4TSDGNWS : 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 well respected brand name 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. These models now come with the 3 Position Notched Buffer/Recoil Tube Assembly under the Fixed Stock if you want to add an adjustable stock in the future. Panzer has included a Mil-spec Picatinny Barrel clamp for any lights or lasers you may want to add. 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. These M4s now come with ambidextrous controls to aid in easier manipulation. This particular model comes with Walnut furniture and is cerakoted in Panzer's new Disruptive Grey finish which looks fantastic. The robust tactical design and legendary reliability of the action make this a must-have shotgun.SpecificationsSKU LNG-PANZER-PAM4TSDGNWSLicense Requirement FFLManufacturer Panzer ArmsMfg.
