Patternmaster Browning Invector Plus 20 Gauge Anaconda Short Range Choke Tube

Anaconda Short Range - engineered to deliver consistent, reliable performance and even patterns with a shorter shot string.This choke offers an effective range of 20-40 yards. On paper you'll see a pattern similar to an Improved Cylinder-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.
