The Beretta MobilChoke 12 Gauge Full Flush Choke Tube (brand part no. JCTUBE13) is a factory MobilChoke choke tube built to Beretta’s own OEM spec, giving 12-gauge Beretta shotgun owners a direct upgrade path for their MobilChoke-threaded barrel. The full constriction tightens the pattern for longer-range shots at driven birds, turkey, or waterfowl decoying tight. Built in the low-profile flush design, it sits inside the muzzle for a clean look with no protrusion to snag on brush or a case. It’s built from stainless steel like the rest of Beretta’s factory choke line, so it holds up to repeated use. Whether you’re rotating chokes between stations at the clays course or dialing in a pattern for the field, this tube swaps in without any gunsmithing.

Key Specifications

• The gauge is 12 Gauge, so it only fits 12-gauge Beretta shotguns built around the MobilChoke choke interface.
• The constriction is Full, which tightens the pattern for longer-range shots at driven birds, turkey, or waterfowl decoying tight.
• It uses the Flush profile, seating entirely inside the muzzle with nothing protruding.
• Body material is Stainless Steel, resisting corrosion through repeated cleaning and wet-weather use.
• It’s a direct fit for Beretta Silver Pigeon I (field models), A300 Outlander, select 687, and select 391 shotguns built around the MobilChoke system.
• It’s sold as a single choke tube, so pattern-testing a full set means picking up companion constrictions separately.

Frequently Asked Questions

What shotguns does this choke tube fit? It’s built for 12-gauge Beretta shotguns with a barrel threaded for the MobilChoke choke system; it will not fit a different gauge or a different maker’s choke interface.

Flush or extended? This is the Flush profile, sitting flush with the muzzle for a clean look.

Is this a factory-correct replacement? Yes, it’s manufactured to Beretta’s own MobilChoke spec, not a generic aftermarket tube, so fit and thread engagement match the factory original.
