Elevate Your Shotgun Performance: An In-Depth Guide to the Carlson's 20 Gauge Invector Plus Improved Cylinder Choke Tube

Are you a shotgun enthusiast looking to fine-tune your shooting performance? Perhaps you're a hunter aiming for more consistent results in the field, or a competitive shooter striving for higher scores on the clays course. For anyone seeking to optimize their 20 gauge shotgun equipped with the Browning Invector Plus system, understanding and selecting the right choke tube is paramount. This comprehensive guide delves into a specific, highly effective option: the Carlson's 20 Gauge Invector Plus Improved Cylinder Choke Tube with a durable Black Nitride finish, featuring a .590 constriction. This accessory is designed to solve common patterning challenges, enhance versatility, and provide a reliable edge in various shooting disciplines.

What is a Shotgun Choke Tube and Why Does It Matter?

Before diving into the specifics of this exceptional choke tube, it's essential to grasp the fundamental role a choke plays in your shotgun's performance. A choke tube is a removable, tapered device that screws into the muzzle end of your shotgun barrel. Its primary function is to control the spread of the shot pattern as it exits the barrel. By constricting the shot column, the choke tube dictates how wide or tight your pattern will be at a given distance.

Imagine trying to hit a fast-moving target with a widely dispersed cloud of pellets versus a tighter, more concentrated one. The right choke tube dramatically improves your chances of hitting your target by ensuring more pellets arrive within a smaller, more effective area. This is why selecting the appropriate choke for your specific shooting activity – whether it's hunting, sporting clays, or self-defense – is as critical as choosing the right ammunition.

Understanding the Improved Cylinder Choke: Precision for Versatile Applications

The choke tube we are exploring, the Carlson's 20 Gauge Invector Plus with a .590 constriction, falls into the "Improved Cylinder" (IC) category. But what does "Improved Cylinder" mean for your shooting?

An Improved Cylinder choke offers a slight constriction, more than a Cylinder choke but less than a Modified choke. This level of constriction typically results in a shot pattern that spreads approximately 45-55% of its pellets within a 30-inch circle at 40 yards. This makes it an incredibly versatile choke, particularly well-suited for closer-range engagements where a rapid and slightly broader spread is advantageous, but still maintaining enough density for effective hits.

When should you use an Improved Cylinder choke? Consider these real-world scenarios:

• Upland Bird Hunting: For fast-flushing birds like quail, grouse, or woodcock in dense cover, an Improved Cylinder choke provides the perfect balance. The slightly wider pattern makes it easier to connect with quick, evasive targets at ranges typically under 30 yards, minimizing the need for pinpoint accuracy and maximizing your chances of a clean retrieve.
• Rabbit and Squirrel Hunting: Similar to upland birds, small game like rabbits and squirrels often present close-range, fleeting opportunities. The IC choke delivers an effective pattern for these scenarios, ensuring a clean and ethical take.
• Close-Range Dove Shooting: When doves are decoying tightly or flying low over a field, an IC choke can be highly effective, especially for the initial shot.
• Skeet Shooting: The official standard for skeet shooting often involves an Improved Cylinder choke (or sometimes even a Cylinder choke) due to the close proximity of the targets, typically ranging from 15 to 25 yards. The IC choke provides a forgiving pattern that covers the crossing targets effectively.
• First Shot in Sporting Clays: Many sporting clays shooters begin with an Improved Cylinder for their first shot on a pair of targets, especially if the first target is closer or presents a quick, ascending presentation. It offers a good balance of spread and density for diverse presentations.
• General Purpose/Walk-Around Choke: If you're unsure what you might encounter, or simply want a versatile option for casual shooting, the Improved Cylinder is an excellent all-around choice for many 20 gauge shotguns.

The Carlson's Advantage: Engineered for Performance and Durability

The Carlson's 20 Gauge Invector Plus Improved Cylinder Choke Tube (model JPCBN20B2/590) is not just any choke; it's a precision-engineered component designed to deliver superior results. Carlson's is a name synonymous with quality and innovation in the choke tube industry, known for its meticulous manufacturing processes and commitment to shooter satisfaction.

Key Features and What They Mean for You:

• Browning Invector Plus Compatibility: This choke tube is specifically designed for shotguns utilizing the Browning Invector Plus choke system. It's crucial to match your choke tube to your shotgun's specific system to ensure proper fit, function, and safety. The Invector Plus system is renowned for its reliability and is found on many popular Browning models, as well as some Winchester and Mossberg shotguns that license the system. This ensures a seamless, secure fit within your barrel.
• 20 Gauge Specificity: Caliber-specific design ensures optimal performance for 20 gauge shotguns. The internal geometry is precisely calibrated for 20 gauge loads, maximizing pattern efficiency and minimizing gas blow-by, which can degrade pattern quality.
• Improved Cylinder Constriction (.590): The exact .590 exit diameter is a testament to Carlson's precision. This specific constriction ensures the ideal balance of pattern spread and density for the applications mentioned above. It's an internal choke, meaning it sits flush with the muzzle, reducing the chance of snagging and maintaining the shotgun's aesthetic.
• Black Nitride Finish: This is a standout feature offering significant advantages. The black nitride process is a chemical heat treatment that enhances the surface hardness, wear resistance, and corrosion resistance of the steel.
  • Durability: The hardened surface means the choke tube will withstand countless shots and resist wear from shot friction, ensuring a longer lifespan and consistent performance over time.
  • Corrosion Resistance: Shotgun choke tubes are exposed to harsh environments, including moisture, gun powder residue, and lead or steel shot. The black nitride finish provides an exceptional barrier against rust and corrosion, making cleaning easier and protecting your investment.
  • Reduced Friction: The slicker surface of the nitrided steel reduces friction as shot passes through, potentially contributing to slightly tighter patterns and less shot deformation, which can lead to more consistent pellet distribution.
  • Aesthetics: The deep black finish offers a sleek, professional look that complements most shotgun designs.
• 17-4 PH Stainless Steel Construction: While the description highlights the Black Nitride finish, Carlson's choke tubes are typically machined from high-grade 17-4 PH stainless steel. This material is chosen for its exceptional strength, heat resistance, and corrosion resistance, providing a robust foundation for the choke tube's performance and longevity, even when shooting various types of shot, including steel shot (always check your shotgun and choke manufacturer's recommendations for steel shot compatibility).

Optimizing Your Shotgun Performance with the Right Choke

Choosing and using the right choke tube is a cornerstone of effective shotgunning. The Carlson's Improved Cylinder choke for your 20 gauge Invector Plus shotgun empowers you to:

1. Achieve More Consistent Hits: By optimizing your shot pattern for closer ranges, you'll find yourself making more decisive hits on targets. No more wondering if your pattern was too tight or too open for the situation.
2. Increase Your Versatility: This single choke tube opens up a wider range of hunting and shooting opportunities. Instead of needing different shotguns for different activities, you can adapt your existing 20 gauge to various scenarios simply by changing the choke.
3. Enhance Your Confidence: When you know your equipment is perfectly matched to the task at hand, your confidence on the range or in the field will naturally soar, leading to better focus and improved execution.
4. Protect Your Investment: A high-quality choke tube like this Carlson's model is an investment in your shotgun's longevity and performance. Its durable construction means it will stand up to rigorous use, protecting your barrel's threads and extending the life of your firearm.

Installation and Care for Your Choke Tube

Installing your new Carlson's choke tube is straightforward:

1. Ensure Safety: Always ensure your shotgun is unloaded and pointed in a safe direction before handling.
2. Clean Barrel Threads: Before installing, lightly clean the choke tube threads and the barrel threads to remove any debris.
3. Apply Choke Grease: Apply a thin layer of choke tube grease or anti-seize compound to the threads of the choke tube. This prevents galling (cold welding), makes installation and removal easier, and protects the threads.
4. Insert and Tighten: Hand-tighten the choke tube firmly into the barrel. For internal chokes, a choke wrench may be needed for final snugging, but do not overtighten. Over-tightening can damage the choke tube or your barrel.

For maintenance, periodically remove your choke tube, clean it thoroughly to remove lead, plastic, and powder fouling, reapply grease, and reinstall. This simple routine will ensure optimal performance and extend the life of your choke and barrel.
