For any serious shotgun enthusiast, hunter, or competitive shooter, optimizing your firearm's performance is paramount. Achieving consistent, dense shot patterns is the key to success, whether you're targeting fast-flying birds, breaking clay pigeons, or taking down small game. This is precisely where the Browning Invector-Plus 20 Gauge Improved Cylinder Flush Choke Tube (SKU: 1130785) proves itself an invaluable asset. Engineered with precision and built to Browning's legendary standards, this choke tube is designed to elevate the capabilities of your 20 gauge shotgun, ensuring reliable performance when it matters most.

Who Needs This Choke Tube and What Problems Does It Solve?

This specific choke tube is an indispensable accessory for a wide array of shotgun users. Are you a hunter who frequently pursues upland game like pheasants, quail, or grouse? Do you enjoy dove hunting, where quick, close-to-medium range shots are common? Perhaps you're a sporting clays or skeet shooter looking to achieve a broader, more forgiving pattern for fast-moving targets. If any of these scenarios describe you, then the Browning Invector-Plus Improved Cylinder choke is designed with your needs in mind.

Common problems this choke tube solves:

• Inconsistent Shot Patterns: Without the right choke, your shotgun's shot spread can be erratic, leading to missed targets or wounded game. This choke tube delivers excellent uniform densities.
• Suboptimal Range Performance: Using too tight a choke for close shots can result in overly concentrated patterns, making it harder to connect. An Improved Cylinder provides the ideal spread for close-to-medium engagements.
• Lack of Versatility: Many shooters desire a choke that offers a balance between spread and density, suitable for a variety of scenarios without constant changes. The Improved Cylinder often serves as a versatile "go-to" choke.
• Durability Concerns: Generic or inferior choke tubes can corrode, warp, or wear out quickly. The 17-4 stainless steel construction of this Browning choke ensures ultimate performance and longevity.
• Compatibility Issues: Finding the correct choke for a specific shotgun system can be confusing. This choke tube is explicitly designed for Browning shotguns featuring the Invector-Plus system, ensuring perfect fit and function.

What is an Improved Cylinder Choke and When Should You Use It?

The term "Improved Cylinder" (IC) refers to a specific constriction type within a shotgun barrel. It sits between a more open "Cylinder" choke and a tighter "Modified" choke. Specifically, this Browning Invector-Plus choke tube has a constriction diameter of approximately .009 inches (or 9 thousandths of an inch).

What does this mean for your shooting?
An Improved Cylinder choke provides a moderate amount of constriction, allowing the shot column to spread out more than a Modified or Full choke, but less than an open Cylinder. This results in a shot pattern that is approximately 45-55% effective at 40 yards, meaning 45-55% of the shot pellets will land within a 30-inch circle at that distance.

When is the Improved Cylinder choke the ideal choice?

• Upland Bird Hunting: For birds like pheasant, quail, and grouse that are often flushed at closer ranges (15-30 yards), an IC choke provides a forgiving pattern that increases your chances of connecting while still delivering enough pellet energy for a clean kill.
• Dove Hunting: Doves are fast and erratic. When they're flying low or at moderate distances, an IC choke offers a pattern wide enough for quick acquisition but dense enough to bring them down.
• Rabbit and Squirrel Hunting: For smaller game in dense cover, where shots are typically close and fast, an IC choke prevents over-patterning and allows for quicker target acquisition.
• Skeet Shooting: The Improved Cylinder is a common choice for skeet shooting due to the close range of targets. It provides a generous pattern to break the clays consistently.
• Sporting Clays (Closer Stations): In sporting clays, which simulates field shooting, the IC choke is excellent for closer targets or presentations requiring a wider spread.
• Home Defense: While choke choice for home defense is a personal decision, an Improved Cylinder can offer a good balance of spread in close quarters while maintaining sufficient density.

This choke tube is engineered to produce patterns with excellent uniform densities, meaning the pellets are evenly distributed within the pattern, minimizing gaps where a target could slip through. This uniform density is crucial for consistent performance, whether you're hunting or competing.

The Browning Invector-Plus System: Precision Engineering for Your Shotgun

Browning's Invector-Plus system represents a significant advancement in shotgun choke technology. Unlike older, shorter choke designs, Invector-Plus tubes are longer, featuring an extended choke taper inside the barrel. This longer taper allows for a more gradual constriction of the shot column, leading to several key benefits:

• Reduced Pellet Deformation: As the shot travels down the barrel and through the choke, a longer, more gradual taper reduces the stresses on the pellets. This minimizes deformation, ensuring more pellets retain their spherical shape, leading to truer flight and more consistent patterns.
• Improved Pattern Uniformity: The extended taper helps to settle the shot column, resulting in remarkably uniform and consistent patterns. This means fewer "holes" in your pattern, increasing your effective hit probability.
• Enhanced Performance: By optimizing the shot's transition from the bore to the outside world, Invector-Plus chokes consistently deliver superior patterning performance compared to shorter, less advanced designs.

Critical Compatibility Note: It is absolutely essential to understand that Invector-Plus choke tubes are specifically designed for Browning shotguns that feature the Invector-Plus system on their barrel(s). This choke tube is NOT for use in shotguns showing "Standard Invector" or "Invector-DS" on the barrel. Attempting to use the wrong choke system can damage your firearm and the choke tube, and compromise safety. Always verify your shotgun's specific choke system before purchasing or installing any choke tube. If your Browning 20 gauge shotgun is marked Invector-Plus, then this choke tube is the perfect match.

The Power of 17-4 Stainless Steel: Durability Meets Performance

The material from which a choke tube is constructed plays a critical role in its performance, longevity, and resistance to harsh conditions. The Browning 1130785 Invector-Plus choke tube is crafted from highly polished 17-4 stainless steel. This specific grade of stainless steel is an exceptional choice for demanding firearm components for several reasons:

• Superior Strength: 17-4 PH (precipitation-hardening) stainless steel is renowned for its high strength and hardness, capable of withstanding the immense pressures generated during shotgun firing. This resistance to wear and deformation ensures the choke maintains its precise constriction and integrity over thousands of shots.
• Exceptional Corrosion Resistance: Stainless steel, by its nature, offers excellent resistance to rust and corrosion, even in damp or saltwater environments. The "17-4" designation refers to its composition, typically containing 17% chromium and 4% nickel, which significantly enhances its corrosion-resistant properties. This is vital for a component that is exposed to propellant gases, residue, and environmental moisture.
• Durability and Longevity: The combination of strength and corrosion resistance means this choke tube is built to last. It will withstand the rigors of hunting trips, competitive shooting seasons, and frequent use without degrading its performance.
• Highly Polished Finish: The highly polished finish of this choke tube isn't just for aesthetics. A smooth, polished surface reduces friction on the shot column as it passes through, further contributing to consistent patterns and minimizing the buildup of fouling. It also makes cleaning easier.

This meticulous material selection underscores Browning's commitment to quality and peak performance, providing shooters with a choke tube that performs reliably year after year.

Flush vs. Extended Choke Tubes: Why Choose a Flush Design?

Choke tubes come in various styles, primarily categorized as "flush" or "extended." The Browning Invector-Plus 20 Gauge Improved Cylinder is a flush style choke.

What are the characteristics and benefits of a flush choke?

• Sleek Profile: A flush choke tube sits entirely within the muzzle of the shotgun barrel, meaning it does not protrude beyond the end of the barrel. This creates a clean, sleek appearance that many shooters prefer.
• No Snagging: Because it doesn't extend beyond the barrel, there's no risk of the choke snagging on clothing, brush, or gun cases, which can be particularly advantageous in dense hunting environments or when quickly maneuvering the shotgun.
• Compactness: Flush chokes maintain the original length of the shotgun barrel, which can be desirable for maneuverability in tight spaces or for aesthetic preferences.
• Protection: Since the choke is recessed, it is less prone to damage from accidental bumps or drops compared to an extended choke that protrudes.

While extended chokes offer benefits like easier changing and often a degree of muzzle protection, the flush design of the Browning Invector-Plus Improved Cylinder choke tube emphasizes a streamlined profile, reduced snag potential, and a classic look without compromising on the patterning performance that Browning Invector-Plus is known for.

Optimizing Your Shotgun Performance with the Right Choke

Choosing the right choke is a critical step in maximizing your shotgun's effectiveness. Here are some key considerations and tips for getting the most out of your Browning Invector-Plus Improved Cylinder choke:

1. Understand Your Target and Range: As discussed, the Improved Cylinder is superb for closer targets and faster-moving game. Always consider the typical distance at which you'll engage your target.
2. Pattern Your Shotgun: The most important step for any serious shotgunner is to "pattern" your shotgun with different chokes and ammunition combinations. This involves shooting at large paper targets at various distances (e.g., 20, 30, 40 yards) to see how your shotgun, choke, and ammunition perform together.
   • How to pattern: Set up a 30-inch circle on a large piece of paper. Shoot from your desired distance. Analyze the density and distribution of pellets within the circle. This will confirm if the Improved Cylinder choke provides the optimal pattern for your specific needs.
3. Experiment with Ammunition: Different brands and types of shotgun shells (shot size, velocity, wad design) can pattern differently even with the same choke. Fine-tune your setup by testing various loads with your Improved Cylinder choke.
4. Practice: Once you've selected and patterned your choke, consistent practice is key. Familiarize yourself with how your shotgun handles and patterns with the Improved Cylinder, building muscle memory and confidence.

Maintenance and Care for Your Browning Invector-Plus Choke Tube

To ensure the long-term performance and reliability of your Browning Invector-Plus 20 Gauge Improved Cylinder choke tube, proper maintenance is essential.

• Regular Cleaning: After each shooting session, remove the choke tube from the barrel. Use a good quality solvent and a brush to clean away carbon buildup, plastic fouling, and powder residue from both the choke tube itself and the choke tube threads inside the barrel.
• Lubrication: Before re-installing, apply a thin layer of choke tube grease or anti-seize compound to the choke tube threads. This prevents the choke from seizing in the barrel due to heat and pressure, making future removal easy.
• Inspection: Periodically inspect your choke tube for any signs of damage, nicks, or bulges. While the 17-4 stainless steel is incredibly durable, extreme abuse or improper installation can still cause issues.
• Proper Storage: When not in use, ensure your choke tube and shotgun are stored in a dry environment to prevent any potential moisture-related issues, although the 17-4 stainless steel is highly resistant to corrosion.

By following these simple steps, your Browning Invector-Plus choke tube will continue to deliver peak performance for countless shooting adventures.
