The Beretta MobilChoke 12 Gauge Improved Modified Flush Choke Tube (brand part no. JCTUBE14) is a factory-correct MobilChoke choke tube engineered to Beretta’s OEM tolerances, giving 12-gauge Beretta shotgun owners a direct upgrade path for their MobilChoke-threaded barrel. As an improved modified choke, it splits the difference between Modified and Full for extended-range wingshooting. The flush profile seats entirely inside the muzzle, keeping the barrel’s lines clean with nothing extending past the crown. Stainless steel construction keeps it corrosion-resistant through repeated range trips and wet field days. 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 Improved Modified, which splits the difference between Modified and Full for extended-range wingshooting.
• 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.
