Carlson invector ds choke tube - Carlson's Choke Tubes Browning Invector DS Sporting Clays 12 Gauge Choke Tube

These chokes do their job like they are supposed to and at a fraction of the cost of a factory choke of which Browning has failed to make in this line. Two Thumbs way up for Carlson's. You can rely on the correct constriction from Carlson and the seal for this choke works fine as I have had no blow by at the bottom of the choke.
