Carlson's Winchester Browning Invector 20 GA Improved Modified Choke Tube

Carlson's cuts these tubes from heat treated stainless bar stock and finishes them to sit flush with the muzzle, so nothing hangs past the end of the barrel and nothing snags in a blind.

Improved modified is the tighter half of the field range. It is the choke people reach for on late season birds and on pass shooting, where the pattern has to hold together well past 35 yards. The threads match the 20 gauge Winchester, Browning Invector and Mossberg 500 pattern, and the tube carries a lifetime warranty.
