The Iver Johnson Choke Tube .410 - Improved Modified Mobil Choke is a precision interchangeable choke system designed for shooters who demand predictable shot patterns and reliable performance in the field. Built for the Iver Johnson .410 shotgun platform, this choke tube enables hunters, sport shooters, and tactical operators to optimize their spread patterns for specific game, distance, and engagement scenarios. The Mobil choke quick-change design eliminates the need for special tools, allowing rapid field adjustments without breaking down the firearm—a critical advantage in dynamic shooting environments where conditions shift rapidly.
The Improved Modified constriction sits in the mid-range of the choke spectrum, delivering a tighter shot pattern than Modified or Improved Cylinder tubes while maintaining adequate pellet spread for ethical kills and reliable hits at moderate distances. This choke density works exceptionally well for small-game hunting, clay target sports, and defensive scenarios where balanced coverage and accuracy are essential. The Mobil choke threading system integrates seamlessly with compatible Iver Johnson barrels, ensuring consistent seating and preventing the gas leakage or pattern fliers that plague poorly fitting aftermarket tubes. Lightweight at 0.05 lbs, the choke adds negligible muzzle weight, preserving the natural handling characteristics of your shotgun.
This choke tube benefits .410 shooters who prioritize versatility—from upland bird hunters navigating dense brush to sport shooters requiring precision on clay targets. Law enforcement and civilian defensive shooters value the ability to swap constrictions for different ammunition loads and engagement distances without reliance on gunsmiths. Installation is straightforward: hand-tighten the tube into the Mobil-threaded barrel until snug, ensuring the choke seats fully without cross-threading. Always verify compatibility with your specific Iver Johnson model before purchase and confirm that your barrel features the Mobil choke thread pattern.
