Let’s Talk About Iver Johnson Arms Iver Johnson Choke Tube 20ga. X-full Mobil Choke Extended
The Iver Johnson Arms Iver Johnson Choke Tube 20ga. X-full Mobil Choke Extended is a seemingly simple accessory, but it plays a crucial role in shotgun performance, especially for specific hunting applications. Manufactured by Iver Johnson Arms, this extended choke tube is designed for 20-gauge shotguns with a Mobil Choke system, promising a very tight pattern ideal for longer-range shots. For experienced shotgun users looking to maximize the range and density of their patterns with lead shot, this choke tube presents itself as an interesting option to explore.
My interest in this choke tube stemmed from a persistent issue I was having with my 20-gauge during late-season pheasant hunts. The birds were getting wise, flushing farther out, and my patterns with a modified choke were too open to consistently bring them down cleanly. An extra-full choke seemed like the logical solution to tighten those patterns and extend my effective range.
Upon receiving the Iver Johnson Arms Iver Johnson Choke Tube 20ga. X-full Mobil Choke Extended, my initial impression was of a solid, well-machined piece. The black finish was even, and the extended design provided a visual confirmation of its purpose. The weight felt appropriate, not too heavy to throw off the balance of the shotgun.
Compared to Carlson’s Choke Tubes and Briley chokes, which are pricier, the Iver Johnson Arms option offered a more budget-friendly alternative. I chose it hoping to achieve similar performance without the higher cost. While I initially approached it with tempered expectations, I was eager to see how it would perform in the field.
Initially, I was optimistic, but slightly concerned about potential limitations. The warning against using steel shot gave me pause, as versatility is always a plus. Still, the promise of tighter patterns with lead shot specifically for pheasant hunting piqued my interest.
Real-World Testing: Putting Iver Johnson Arms Iver Johnson Choke Tube 20ga. X-full Mobil Choke Extended to the Test
First Use Experience
I tested the Iver Johnson Arms Iver Johnson Choke Tube 20ga. X-full Mobil Choke Extended during a late-season pheasant hunt in South Dakota. The conditions were typical for that time of year: cold, dry, and with a light wind. I was primarily targeting wild pheasants in harvested cornfields.
The choke tube performed as expected in creating significantly tighter patterns at longer ranges. Birds that would have flown away unscathed with my previous choke were now folding cleanly at 40-50 yards. The increased pattern density was noticeable, resulting in more consistent kills.
Installation was simple, requiring only a choke tube wrench. No issues arose during installation or removal.

After several weeks of use, the Iver Johnson Arms Iver Johnson Choke Tube 20ga. X-full Mobil Choke Extended has held up remarkably well. There are no visible signs of wear and tear despite frequent use and cleaning. The finish remains intact, and the threads show no signs of damage.
Maintenance has been straightforward. Regular cleaning with a bore brush and solvent keeps it in good condition.
Compared to my previous experiences with extended chokes from other brands, this Iver Johnson Arms choke has performed admirably, offering comparable performance at a more accessible price point. While it lacks the versatility of being able to handle steel shot, it excels in its intended application: maximizing lead shot performance for hunting.
