Engineered for the short-stroke gas piston (ARGO) Benelli M4 platform, this OEM assembly delivers the correct fit and geometry for ARGO-equipped receivers, including M1014 variants. It is a direct factory component, not an aftermarket substitute.
The barrel is roll-marked for 12 gauge 3" (76 mm) and indicates compatibility with both 2 3/4" and 3" shells, providing flexibility in ammunition selection as intended by the original spec.
A fixed protected-post front sight tower is integral to the barrel. Its height is designed to mate with the M4’s receiver-mounted ghost-ring rear sight for proper sight alignment on this platform.
Italian manufacture and proofing are evident, with IT21 and star-style proof symbols present. The steel barrel and matching magazine tube show factory-correct features, including the tube’s external threads, two shallow annular grooves, and an installed knurled cap. No magazine spring or follower are included.
