Why are Beretta Optima choke tubes so thick?
As noted above under the Optima-Choke Plus section, the extended use of high performance steel and metal alloy non-toxic shot imparts considerable stresses. In the case of the Optima-Choke Plus part of the solution was to use a choke tube design offering a thicker choke tube wall to better resist these forces.
What kind of choke system does a 680 series Shotgun use?
The Mobil-Choke system continues to be the mainstay of the 680 series field grade Over&Under shotguns. The iconic parallel design of the Beretta choke tubes creates a more gradual taper inside which gently transitions into a parallel section that runs to the muzzle end of the tube.
When did Beretta come out with the Optima barrel?
