Technical Specifications

Why Choose the Iver Johnson Improved Modified Choke?

When performance matters, the Iver Johnson Improved Modified choke stands out for its balanced pattern and dependable construction. The MOBIL design offers a tighter shot grouping than a standard Modified, yet it remains forgiving enough for fast target acquisition. This makes it perfect for:

• Upland game hunting – where tight patterns increase chances of clean kills.
• Sporting clays and skeet – delivering consistent rings for repeatable scores.
• Home defense – providing a controlled spread to maximize coverage without over‑penetration.

Installation & Care Instructions

1. Ensure the shotgun is unloaded and the barrel is clear of any ammunition.
2. Using a choke wrench, align the choke threads with the barrel’s threading.
3. Turn the choke clockwise until it is hand‑tight; then give a final ¼ turn with the wrench for a secure fit.
4. After installation, fire a few test shots to confirm proper pattern alignment.
5. Wipe the exterior with a clean cloth after use to maintain the chrome finish and prevent corrosion.
