Beretta Mobilchoke Ported Edition 12 Ga Corrosion Resistant Stainless Steel Choke Tubes

BERETTA CHOKE TUBE MOBILCHOKE "PORTED EDITION" 12 GA These chokes can be used on all Mobilchoke barrels. Made of high quality steel, they are of a great stress resistance due to heat treatments. They are subjected to a special coating that guarantees high protection to corrosion. Their shape has been studied in order to guarantee installation and de-installation without specific tools. The indication of the constriction is indicated by the stars at the top. These chokes are for 12 gauge guns only. CHOKE TUBE COSTRICTION: - Full - Improved Cylinder - Cylinder - Improved Modified - Improved Cylinder ABOUT MOBILCHOKE SYSTEM Introduced in the mid 1980's the Mobilchoke tube system was first available for the model S687L over and under and later carried through virtually every model of fixed breech and semi-automatic gun. At this time the Mobilechoke is the only choke tube system adapted by Beretta to 12, 20, 28 gauge and .410. The Mobilchoke system continues to be the mainstay of the 680 series field grade over and under guns and the A300 Outlander semi automatic gun.The conical parallel design of the Beretta choke tubes creates a more gradual taper inside the choke tube which gently transitions into a parallel section that runs to the muzzle end of the tube. The conical parallel design results in reduced shot deformation, improved pattern uniformity and increased pattern density.

• STEEL CHOKE TUBES - Manufactured from high strength steel, these choke tubes are of a great stress resistance due to heat treatments and have the ability to withstand the rigors of steel shot
• COMPATIBILITY - These choke tubes are for 12 gauge guns only and can be used on all Mobilchoke barrels; the start of the threaded portion of the 12 gauge Mobilchoke tube is located a nominal 41.5 mm (1.63 inch) from the breech end of the choke tube
• EASY TO USE - Their shape has been studied in order to guarantee installation and de-installation without specific tools; their design results in reduced shot deformation, improved pattern uniformity and increased pattern density
• ANTI-CORROSION PROTECTION - These durable choke tubes are covered with a special coating that guarantees high protection to corrosion and long-lasting performance
• ENGRAVED DETAILS - Every Beretta choke tube has information engraved on the tube to identify the manufacturer (PB), the constriction (F, IM, M, IC, CYL), the approval for steel shot use (SP) and the choke type
