The Real Deal Behind the Iver Johnson Arms Iver Johnson Choke Tube 20ga. Modified Mobil Choke
For years, I’ve relied on a specific, slightly older 20-gauge shotgun for a variety of tasks that fall outside the typical hunting scenario – think pest control on a rural property and occasional sporting clays. Recently, the original modified choke tube on that trusty scattergun decided it had seen enough, developing a slight wobble that made me uneasy. This led me on a search for a reliable replacement, and that’s how I came across the Iver Johnson Arms Iver Johnson Choke Tube 20ga. Modified Mobil Choke. My primary goal was to find a simple, durable replacement that wouldn’t break the bank and would maintain the shotgun’s performance.
Upon receiving the choke, my initial impression was one of straightforward utility. It felt solid in my hand, with a reassuring heft that spoke of good materials. The Iver Johnson Arms name, while perhaps more associated with historical firearms, lent a certain sense of established craftsmanship to this small but critical component. I considered a few other generic Mobil choke tubes, but the combination of the manufacturer’s reputation and the specific “Modified” constriction for general use pushed me towards this particular option. A small sigh of relief escaped me; sometimes, simply finding a direct, no-nonsense replacement is the best outcome.
Real-World Testing: Putting Iver Johnson Arms Iver Johnson Choke Tube 20ga. Modified Mobil Choke to the Test
My testing environment was a familiar blend of practical application and recreational shooting. The choke tube was installed in my well-worn 20-gauge over/under shotgun, and its first real duty was clearing out a persistent flock of starlings that had taken up residence in a barn loft. This involved a mix of close-quarters shots, necessitating a consistent and predictable pattern. Following that practical application, I took the shotgun to my local outdoor range for some sporting clays, which offers a more diverse range of target presentations and distances.
Over the course of several range sessions and practical uses, the choke performed admirably. It was subjected to the usual rigors of repeated firing, including exposure to a light morning dew and the fine dust kicked up from the clays at the range. The Iver Johnson Arms Iver Johnson Choke Tube 20ga. Modified Mobil Choke proved to be exceptionally easy to use; it threaded in smoothly with no resistance, and the familiar click of it seating properly was an immediate confirmation of a good fit. My only minor surprise was how little I thought about it once it was installed – it simply worked, which is precisely what you want from a component like this.
Extended Use & Reliability
After several months of intermittent but regular use, this choke tube has proven its worth. It remains firmly seated and shows no signs of loosening, even after numerous takedowns and reassemblies of the shotgun for cleaning. The steel construction has held up remarkably well, with no visible cracks or significant wear. The patterns it produces remain consistent, which is crucial for both accuracy and effectiveness in various shooting scenarios.
Maintenance has been straightforward. A quick clean with a bore snake and a light application of gun oil after each use is all it requires. I’ve paid particular attention to ensuring no debris gets lodged in the threads, a practice that has served me well with all my firearms. Compared to some budget aftermarket chokes I’ve tried in the past that developed flyers or inconsistent patterns after just a few boxes of shells, this Mobil choke system from Iver Johnson Arms has far exceeded expectations for its class. It holds its own against more expensive options, offering a dependable performance that reassures me every time I shoulder my shotgun.
Breaking Down the Features of Iver Johnson Arms Iver Johnson Choke Tube 20ga. Modified Mobil Choke
Specifications
The Iver Johnson Arms Iver Johnson Choke Tube 20ga. Modified Mobil Choke is a straightforward piece of engineering designed for reliability and effectiveness. It’s constructed from high strength steel, which provides the necessary durability to withstand the pressures of firing and the elements. As the name suggests, this is a choke tube specifically for 20 gauge shotguns and utilizes the widely adopted Mobil Choke system, ensuring compatibility with a broad range of modern shotgun models. The constriction type is Modified, which is ideal for general-purpose shooting, offering a balance between pattern density at moderate distances and a slightly wider spread for closer targets.
The Mobil Choke system is a significant advantage, meaning this choke tube can be used with break-open shotguns to duplicating shotguns, as long as they are manufactured to accept this standard. The black finish is practical, offering a subtle appearance that won’t draw unnecessary attention while also providing a layer of corrosion resistance. A key detail mentioned in its description is its ability to help reduce recoil, a benefit that not only improves shooter comfort but also contributes to the longevity of the choke and firearm by mitigating stress. For anyone with a shotgun chambered for 20-gauge that accepts Mobil chokes, this unit offers a solid set of specifications for a very reasonable price.
Performance & Functionality
In terms of its primary job, throwing a consistent and predictable shot pattern, the Iver Johnson Arms Iver Johnson Choke Tube 20ga. Modified Mobil Choke performs exceptionally well for its intended purpose. The Modified constriction strikes a fine balance, delivering tight enough patterns for effective engagement of sporting clays at moderate ranges while still providing a usable spread for those closer pest control situations. I experienced very few fliers, and the patterns were notably uniform across several different brands and types of 20-gauge lead shot ammunition I tested.
The advertised benefit of recoil reduction is subtle but noticeable. When firing strings of shots, especially with heavier loads, the perceived kick felt slightly softer than with some other chokes I’ve used. This is a welcome bonus, making longer shooting sessions more comfortable and potentially improving follow-up shot accuracy. Considering its accessible price point, the performance is not just meeting expectations; it’s exceeding them, offering a level of consistency and comfort usually found in more premium offerings.
Design & Ergonomics
The design of this choke tube is purely functional, prioritizing robust construction over elaborate aesthetics. The high strength steel construction gives it a solid feel, and the machined external surface provides enough purchase for easy hand-tightening and removal. While it doesn’t feature aggressive knurling or specialized grip enhancers, the black finish offers a decent, non-slip grip for most users.
Installation and removal are intuitive; it’s a simple screw-in component that anyone familiar with basic shotgun maintenance can handle. The threading is smooth and precise, indicating good manufacturing tolerances. There’s no real “learning curve” with this product, as its operation is inherently simple. The absence of any complex parts or mechanisms means there are fewer potential points of failure, contributing to its overall user-friendliness.
Durability & Maintenance
The high strength steel composition is the cornerstone of this choke tube’s durability. After months of regular use, including exposure to varying environmental conditions and countless rounds of ammunition, there are no signs of significant wear. The black finish has resisted scratching and corrosion admirably.
Maintenance is minimal. As mentioned, a simple clean with a bore brush or snake and a light application of gun oil is sufficient to keep it in top condition. It’s important to periodically check the threads for any fouling or damage, but this is standard practice for any screw-in choke. For its intended use with lead shot and standard loads, this choke tube is built to last for a very long time, easily justifying its cost over the long haul.
