What is a poly choke?

A poly choke is an adjustable shotgun choke that allows the shooter to modify the spread of shot from a shotgun shell. It consists of a tapered sleeve that can be rotated to change the constriction and, consequently, the pattern of the shot as it exits the barrel. This versatility enables shooters to adapt to different shooting situations, such as hunting or sport shooting, without needing to change the choke tube. Poly chokes are often favored for their convenience and ease of use.
