Benelli Unveils M2‑G1 Shotgun With Rear Piston Operated Gas System

The company says the new rear‑piston design and tactical ergonomics aim to cut fouling and boost consistency for defense and competitive use.

Overview

  • Benelli announced the M2‑G1 as a 12‑gauge tactical shotgun that uses a new Rear Piston Operated (R.P.O.) gas system built around dual short‑stroke pistons placed near the chamber.
  • The company claims the R.P.O. layout reduces fouling exposure and improves long‑term cycling consistency compared with prior M2 operating systems.
  • Benelli lists tactical upgrades including a beveled loading port, enlarged controls for gloved use, an upgraded pistol grip, a five‑position collapsible stock, and an extended 7+1 capacity option.
  • Initial models all carry an 18.5‑inch barrel and MSRPs from $1,829 to $2,149 depending on stock and finish, with both 5+1 and 7+1 configurations offered.
  • Independent range tests and long‑term reliability data have not yet been published, so buyer and agency decisions will depend on forthcoming hands‑on reviews and durability results.
