Description: Benelli M4 Semi-Auto Shotgun - 12 Gauge 3" - Used; Excellent Condition - Upgraded Tactical Shotgun Benelli M4 – The U.S.M.C. Approved Tactical Shotgun – Upgraded for Maximum Capacity For sale is a Benelli M4 semi-automatic shotgun, chambered in 12 Gauge (2 3/4" and 3"). This is the shotgun that sets the standard for tactical shotguns – the same platform that was designed for and approved by the U.S. Marine Corps. This example is in excellent used condition and has been upgraded with several tactical enhancements. The Benelli M4 features the Auto-Regulating Gas-Operated (A.R.G.O.) system – a piston-driven design that makes it fast-cycling and ultra-reliable, regardless of ammunition type. This example has an 18.5-inch barrel with a Modified (M) choke installed (uses Benelli/Beretta Standard/Mobil chokes). The shotgun features a tactical pistol grip stock, adjustable rear ghost-ring sight, and windage-adjustable front sight. The original receiver-mounted Picatinny rail has been replaced with an upgraded version that also adds 8-shell capacity shell holders on the left-hand side. The foregrip has been replaced with an upgraded barrel shroud that features Picatinny rails at the 12, 3, 6, and 9 o'clock positions (note: the 12 o'clock rail is not seamless with the receiver rail).
