What’s Included
- Benelli M4 Tactical 12 Gauge shotgun with 18.5" barrel
- Factory-installed M choke
The heart of the M4 is Benelli’s patented A.R.G.O. (Auto-Regulating Gas-Operated) system. Two chrome-lined pistons positioned just forward of the chamber drive the action, offering clean operation and consistent reliability with a wide range of loads.
A one-piece magazine tube offers increased capacity without extensions, while the alloy receiver is drilled and tapped for the included 1913 top rail, streamlining optics mounting. Ghost-ring sights—hooded post front and fully adjustable rear—provide fast target acquisition in any light.
The 18.5" steel barrel is heavy-walled, chrome-lined, and threaded for Benelli’s choke system. The installed Modified choke balances pellet density with spread, making it a versatile choice for defensive, duty, or competition use.
A fixed, pistol-grip synthetic stock with integral sling slot delivers a 12.5" length of pull and ends in a textured recoil pad. The matching one-piece forend features longitudinal ribs for positive control, and the cross-bolt safety sits within easy reach of the trigger guard.
Roll-marked “BENELLI-ITALY” and carrying serial number Y071987L, this Italian-made shotgun weighs roughly 7.8 lb unloaded and measures 40" overall—compact enough for maneuverability while retaining the durability expected from Benelli’s M4 line.
