Shotgun Choke Tube: This product is a removable shotgun choke tube designed for the compatible shotgun gauge and thread system identified in the title and specifications. It installs at the muzzle of a compatible shotgun barrel and is used to manage the shot pattern for its intended shooting application.

Anaconda — engineered to deliver consistent, reliable performance and even patterns with a shorter shot string.

This choke offers an effective range of up to 70 yards. On paper you'll see a pattern similar to an Extra Full like choke, but due to the patented "Coil Zone", that is a Precision-machined channel with a left twist to counter the natural right spin of the ammunition load, the shot string is dramatically shorter. That means more pellets on target simultaneously for cleaner kills. All Patternmaster Anaconda tubes are made from aircraft quality 17-4ph stainless steel and powder coated with a Military-Spec, Chemical Agent Resistant Coating (CARC) for a lifetime of durability.

Safe with lead, or Non-Toxic Turkey loads. Comes in Oliver Drab Green finish and is non‑ported.
