The Beretta MobilChoke 20 Gauge Improved Cylinder Flush Choke Tube (brand part no. JCTUBE24) is a genuine Beretta MobilChoke choke tube, machined to the same spec as the factory original, giving 20-gauge Beretta shotgun owners a direct upgrade path for their MobilChoke-threaded barrel. As an improved cylinder choke, it opens the pattern for closer targets like upland birds flushing at short range. The flush profile seats entirely inside the muzzle, keeping the barrel’s lines clean with nothing extending past the crown. Stainless steel construction matches the rest of Beretta’s OEM choke lineup for long-term durability. 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 20 Gauge, so it only fits 20-gauge Beretta shotguns built around the MobilChoke choke interface.
• The constriction is Improved Cylinder, which opens the pattern for closer targets like upland birds flushing at short range.
• 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 compatible with any Beretta 20 Gauge shotgun barrel threaded for 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 20-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.
