Carlson's Invector DS tubes are manufactured from 17-4 heat treated stainless steel to withstand heavy buffered turkey shotshells. These choke tubes produce extra tight patterns with copper plated and buffered lead turkey shotshells. These chokes produce dense patterns and carry a lifetime warranty. The Extended Turkey Chokes extend approximately 1" from the end of the barrel. These chokes have a matte blue finish.
*No Steel Shot Larger than #4 may be used in our Turkey Choke Tubes
Carlson's has found the .665 Extended Turkey Choke Tube to produce the most consistent patterns with turkey loads.
