The M4, a true classic of Benelli production, is also available in the M4 T-Pro version. The particular telescopic kick pistol grip allows, by pressing a special button, to vary the length of the weapon. M4 T-Pro is equipped with a rail, mounted on the dipstick and on which the optics and different types of accessories can be housed. It is also equipped with an adjustable ghost ring viewfinder, a fixed front sight and a piccatinny rail on the receiver. Aims may be equipped with luminescent references for shooting in low light conditions.
What distinguishes Benelli from the competition is the ultra-reliability and quality built into every gun based on superior technology and craftsmanship. Benelli’s Inertia Driven® operating system incorporates total efficiency with complete reliability.
The A.R.G.O Piston-Driven System is a unique, short-stroke, dual-piston design developed for the M4 Tactical shotgun in 1998 for the U.S. Marine Corps. It was later adopted as the U.S. Joint Services combat shotgun—and remains so today.
The gas port is located just forward of the chamber, where the gases are hotter and cleaner. This results in less fouling and more reliable cycling. Pistons push directly against the bolt, for fast operation and minimum vibration. There are no connecting linkages or heavy action bars under the forend, which add weight.
