These Optima Choke tubes are external versions for 12 gauge shotguns. They are longer and slimmer than conventional Mobilchoke tubes. Thanks to the elongated cone they minimize pellet deformation and improve shot patterns. The various versions are fully interchangeable on 12 gauge guns with Optima Bore barrels. These choke tubes are for 12 gauge shotguns with the Optima-Choke system only.

***Please note that the constriction cut off for factory made choke tubes with steel shot is a Modified constriction, factory made choke tubes with a constriction tighter than Modified such as Improved Modified and Full are not suitable for use with steel shot.

Additionally, rifled or sabot slugs should not be used in a factory made choke tube with a constriction tighter than Improved Cylinder.***
