Iver Johnson Stainless Steel .410 Extended Improved Cylinder Mobil Thread Choke

The Iver Johnson choke tube in .410 Bore is crafted in stainless steel for durability and corrosion resistance, featuring an extended design with the improved cylinder choke to help optimize pattern density at practical shooting distances.

With no unnecessary frills, the Iver Johnson choke tube delivers practical value by combining durable materials, a proven choke design, and thoughtful dimensions that align with common .410 bore shotguns, supporting confident, accurate, and ethical harvests.
