Carlsons Delta Waterfowl Extended Choke 20 Gauge Winchester Invector Mid-Range .600 - Black

The Carlson's Delta Waterfowl extended choke tube is purpose-built for the waterfowl hunter who needs tighter, denser patterns out of a 20 gauge shotgun. Machined from 17-4 stainless steel and finished in a non-reflective black coating, this choke is engineered with a 25% longer parallel section in the constriction than a conventional choke, throwing more consistent patterns with fewer flyers at extended ranges over decoys and open water.

This Delta Waterfowl is a Mid-Range choke with a constriction diameter of .600, threading directly into any Winchester Invector choke-system barrel and also fitting Browning Invector and Mossberg 500 barrels that share the same Invector thread pattern. The extended body projects beyond the muzzle for quick visual identification in the field, and the end is knurled to allow easy hand installation and removal without special tools. Sold as one choke tube.
