Accessories for Benelli M4

The Benelli M4 is a gas-operated semi-automatic tactical shotgun using the Auto Regulating Gas Operated (ARGO) system, adopted by the US Marine Corps and law enforcement agencies worldwide. In competition, the M4 is used in tactical shotgun events and 3-gun, where its reliability with a wide range of loads -- from light target shells to full-power buckshot -- is a significant operational advantage.

Upgrades for the Benelli M4

The Benelli M4 can be tailored across the main competition upgrade areas:

• Stocks – an adjustable stock dials in length of pull and cheek height so the gun mounts the same way every time.
• Handguards and forends – a replacement forend changes where and how your support hand drives the gun, improving control through fast transitions.
• Tube extensions – a magazine tube extension adds shell capacity beyond the factory limit, so fewer reloads break up a stage.
• Red dot mounts and sights – a mounted optic gives a single focal plane for faster acquisition without permanent changes to the receiver.
• Cheek rests – a raised cheek piece keeps your eye consistently behind the optic on every mount.
• Charging handles and controls – enlarged controls are faster and surer to operate under speed.
