Carlson's Choke Tubes Delta Waterfowl Extended Mobil 12GA Choke

Extending just 3/4" outside your shotgun barrel to protect against damage to your barrel caused by prolonged steel shot use, the Carlson's Choke Tubes Delta Waterfowl Extended Mobil 12GA Choke is a direct-thread choke tube compatible with most choked 12-gauge shotgun barrels. This choke features 17-4 stainless steel construction with a knurled surface for maximum strength and wrench-less installation and boasts an elongated parallel section for use with larger steel shot in tighter choke constrictions. Backed by a lifetime warranty. Made in USA.

Note: Do not use steel faster than 1550 FPS or steel shot sizes larger than BB through the long-range choke tube.
