Each choke tube is knurled on the end to allow for quick and easy removal. Each choke tube has the constriction and size laser marked on the end and body for easy reference.
Steel shot may be used through these choke tubes with exceptional results. Do not shoot steel shot larger than BB or any steel load faster than 1550 FPS through the Long Range Constriction. Loads that exceed this size and speed should be used with the Mid Range choke tube.
These chokes are backed by Carlson's lifetime warranty.
