Iver Johnson Choke Tube .410 - Full Mobil Choke

The Iver Johnson Choke Tube .410 - Full Mobil Choke is a precision shotgun choke designed for shooters who demand tight, consistent patterns downrange. Built for .410 bore shotguns, this full choke tube serves hunters, sport shooters, and tactical operators requiring maximum shot density at extended distances. The Mobile choke system allows rapid field changes without gunsmithing, enabling shooters to adapt to varying targets and hunting scenarios in seconds.

This choke tube utilizes Mobile choke-style threads, the industry-standard quick-change system that ensures reliable engagement and repeatable performance across compatible Iver Johnson shotguns. The full constriction pattern tightens the shot column as it exits the barrel, maintaining pellet cohesion and energy retention over distance—critical for ethical hunting and competitive accuracy. The compact 2.95-inch length and lightweight 0.04 lbs construction minimize impact on barrel harmonics while remaining robust enough for field use in demanding conditions. Precision-manufactured threading guarantees a secure fit and corrosion-resistant performance.

Tactical shooters, upland hunters, and clay target competitors benefit most from full choke selection when pursuing distant targets or situations demanding tighter patterns than improved or modified options provide. Installation is straightforward: simply unscrew the existing choke tube and hand-thread this unit until snug—no special tools required. Ensure compatibility with your Iver Johnson .410 shotgun before purchase. This choke integrates seamlessly into any Mobile-threaded .410 platform, giving shooters immediate access to proven full-choke ballistics.
