A choke tube is a device that is attached to the muzzle of a shotgun. Its purpose is to control the spread of the shot, making it more effective at long range. There are different types of choke tubes, each with its advantages and disadvantages.
The most common type of choke tube is the full choke. This type of tube constricts the shot pattern tightly, making it ideal for hunting or clay shooting. However, because the shot pattern is so tight, full chokes can be difficult to use in self-defense situations.
Another type of choke tube is the modified choke. This type of tube still provides some degree of constriction, but not as much as a full choke. This makes it a good choice for self-defense, as it will still allow you to hit your target at a distance, but is less likely to over-penetrate and cause collateral damage.
Finally, there is the cylinder choke. This type of choke provides no constriction at all, making it the best choice for close-range situations.
No matter what type of choke tube you choose, be sure to practice with it so that you are familiar with its performance.
