Also known as: M4 EXT, M4 EXT Tactical
Overview
The Benelli M4 EXT is a 2026 factory tactical evolution of Benelli's legendary gas-operated M4 combat shotgun. It ships with a flush-fit extended magazine tube for 7+1 capacity, a five-position collapsible stock with integrated pistol grip, ghost-ring sights, a Picatinny optics rail, and an oversized bolt release, packaging the upgrades that serious users had long been bolting on themselves. It retains the M4's self-regulating A.R.G.O. (Auto-Regulating Gas-Operated) twin short-stroke piston system.

Notes
The EXT's defining feature is its full-length extended magazine tube, raising civilian capacity from the long-standard hobbled 5+1 to 7+1 (up to 9 total when ghost-loaded). Offered in H2O Titanium Cerakote, FDE, and MultiCam Black. Retailer weight figures vary (7.8 to 8.4 lb).
Background
The base M4 is the famous M1014, adopted by the U.S. Marine Corps in 1999 as the first semi-automatic shotgun in U.S. military service; for about 25 years U.S. civilians were stuck with a 5+1 tube while military and law-enforcement versions ran full-length tubes, and the EXT is Benelli's official answer.
