BENELLI MR1 TACTICAL RIFLE 5.56 x 45 (.223)
PISTOL GRIP Synthetic Stock
A self defense rifle has to perform the first time, every time.
The ultra-reliable A.R.G.O. system incorporated into the new Benelli
MR1 does it for the U.S. military, and makes the MR1 the best home
defense rifle available. MR1 self defense guns are chambered in 5.56
mm NATO (.223 Remington) and use the battle-proven Auto Regulating
Gas Operated (A.R.G.O.) system—the same system developed by Benelli
for the M1014 (M4) and used for over a decade in multiple conflicts
by the United States Marine Corps.
Built to the same tough military specifications and embodying the
solid reliability that the U.S. Marines rely upon, the MR1 has no
equal among home defense weapons. It features a stainless steel,
self-cleaning piston that operates directly against the proven
rotating bolt, thereby eliminating the need for complex linkages
found on other, inferior gas systems. This piston-driven system,
perfected by Benelli, incorporates a gas port located just forward of
the chamber, where the gases are hotter and cleaner, resulting in
less fouling and more reliable cycling. The result—a Benelli
carbine with features rivaling all other home defense rifles,
including Marine—tough reliability and the ability to function in
the harshest environmental conditions.
Auto-Regulating Gas-Operated (A.R.G.O.)
On August 4, 1998 Benelli delivered five shotgun samples featuring
the A.R.G.O. system to Aberdeen Proving Ground, Maryland. The guns
were put through an intensive, grueling test for safety, function and
performance. Subjecting them to mud, sand, baking heat and extreme
cold, the guns beat out the competition to be chosen as the new U.S.
“Joint Service Combat Shotgun.” Benelli’s patented
Auto-Regulating Gas-Operated (A.R.G.O.) system has more than met the
needs of the U.S. Marines’ M1014 semiautomatic ï¿½ an
ultra-reliable, battle-proven shotgun.
The A.R.G.O. Piston-Driven System is also the heart of the
Benelli’s R1 and MR1 rifles, featuring simplicity, sturdiness and
accuracy, all packaged in an ingenious design.
Upon firing a Piston-Driven gun, single port, located just forward
of the chamber, bleeds gases where they are hotter and cleaner. The
results are less fouling and more reliable cycling. A short-stroke,
self-cleaning piston and two tappet pistons push directly against the
R1’s bolt body, eliminating the need for connecting linkages or
heavy action bars. Because the pistons push directly against the
bolt, they move only ½-inch for complete and rapid cycling with
Synthetic tactical stock with pistol grip.
