If you own a Remington 12-gauge shotgun, then you are probably interested in more choke tubes so you can shape how your shots are going to spread after they leave the bore. The importance of adding a choke tube to a shotgun is so you can add more constriction to your shots. Otherwise, the shots will just spread wide as soon as they leave the bore and this will make it very difficult to aim at small targets that are in your line of fire. To install a choke tube into the bore of your shotgun’s barrel, you need the right choke tubes and installation tools in order to make sure that it is done right.
