Optimachoke Plus are the best in term of performance, resistance and reliability. Thanks to an elongated cone, Optimachoke Plus guaranties an excellent shot pattern.The new shape improves resistance to the pressure and speed created by 3.5” cartridges with steel shot. These choke tubes will only fit the 12 Gauge Optimachoke Plus shotguns.
Extra Full, Full /*, Light Full and Improved Modified /** constrictions cannot be used with Steel shots.
Where can I find the constrictions or dimensions on my Beretta choke tubes?
How can I tell which choke tubes fit in my shotgun?
