Crio/Crio Plus--Sporting Clays Choke Tubes are made from 17-4 stainless and precision machined to produce a choke tube that patterns better than standard choke tubes. They  feature a 25% larger parallel section in the choke thus throwing tighter/denser patterns than Flush Mount Choke Tubes.

Each choke tube is knurled on the end to allow for quick and easy removal and has the constriction laser marked on the end for easy reference.

Fits newer Benelli models.

Lead shot, Steel Shot, Copperplated Shot, Nickel Shot, Hevi-Shotshells™, and Buck Shot can be used in these Sporting Clay Choke Tubes.

Steel shot larger than BB should not be used in any Sporting Clays Choke Tube tighter than Full Constriction.

Backed by Carlson's lifetime warranty.
