Benelli released the M2-G1 tactical shotgun with MSRP under 2000 dollars using gas-operated dual rear pistons called RPO, nearer the M4 ARGO than earlier M2 inertia designs. Four models are available with more planned featuring five-position pistol-grip or traditional stocks plus ghost-ring sights, 18.5-inch barrel, Picatinny rail and M-LOK handguard on a right-hand-only 7+1 gun for Mobile chokes and 3-inch shells. It positions between the M2 and costlier M4 with similar recoil and full reliability even suppressed, the M4 better for heavy use while the Beretta 1301 cycles faster but dirtier.
