16 gauge Rizzini chokes. The gauge that carries like a 20 and hits like a 12. Flush-fit tubes finish level with the muzzle — clean lines, nothing to snag in cover — and are available in five constrictions: Cylinder, Improved Cylinder, Modified, Improved Modified and Full.
Nominal bore is .662″ (16.8 mm). Check the code stamped on the tube you already own before ordering.
