Iver Johnson Choke Tube 12ga. - Full Mobil Choke

The Iver Johnson Choke Tube 12ga. Full Mobil Choke is a precision-engineered shotgun choke designed for shooters who demand tight, consistent patterns downrange. Built to Iver Johnson specifications, this full choke tube suits tactical operators, hunters, and competitive shooters requiring maximum shot density at extended distances. The Mobil choke style threading allows quick field swaps between choke configurations, making it an essential accessory for any serious 12-gauge platform.

Full choke constriction delivers the tightest pattern available, concentrating pellets in a smaller spread ideal for long-range shooting and precision applications. The Mobil choke design uses standard threaded connection geometry, enabling tool-free installation and removal in seconds—critical when tactical or hunting situations demand rapid choke selection. At just 0.06 lbs, this compact tube adds negligible weight while maintaining structural integrity under repeated cycling and high-pressure loads typical of tactical shotgun use.

Law enforcement and military personnel benefit most from the versatility of maintaining a full choke in their accessory kit alongside more open patterns for close-quarters scenarios. When precision matters—whether in breaching operations, patrol duties, or sport shooting—the tight constriction ensures reliable performance. Compatible with any 12-gauge shotgun featuring Mobil-style threaded choke ports, installation requires no gunsmithing; simply unscrew the existing choke and thread this tube hand-tight into the barrel.
