For those who demand peak precision and consistent shot patterns, the EAR JPCBN20A2/570 High Voltage Rem Choke for 20 gauge shotguns, with its specialized .570 constriction and durable Black Nitride finish, stands out as an exceptional choice designed to elevate your shooting experience. This isn't just another accessory; it's a precision-engineered tool built to unlock your shotgun's true potential, ensuring your pellets fly true and deliver maximum impact precisely where you need it.

The Essential Role of a Shotgun Choke

Before diving into the specifics of this remarkable choke tube, let's understand why chokes are so indispensable. A shotgun choke is a tapered constriction at the muzzle end of a shotgun barrel that controls the spread of the shot pattern as it exits the barrel. Without a choke, shot pellets would scatter rapidly, losing energy and density over short distances. By narrowing the barrel just before the pellets emerge, a choke tube effectively "squeezes" the shot column, keeping the pellets together for a longer period, thus creating a denser and more effective pattern at varying ranges.

Choosing the right choke is paramount for different shooting disciplines. For instance, an open choke (like Cylinder or Improved Cylinder) allows for a wider, faster-spreading pattern, ideal for close-range targets like upland birds flushed at short distances or fast-moving clay pigeons. Conversely, tighter chokes (such as Full or Extra Full) deliver a much denser, narrower pattern, essential for extending your effective range for small, challenging targets like turkeys or for breaking distant clays. The ability to swap out chokes allows a single shotgun to be incredibly versatile, adapting to different game, distances, and shooting scenarios. Without the right choke, you might find your patterns too wide for ethical long-range shots or too tight for snap shots at close quarters.

Introducing the EAR High Voltage .570 Rem Choke for 20 Gauge

The EAR JPCBN20A2/570 High Voltage Rem Choke is specifically engineered for 20 gauge shotguns utilizing the Remington Rem Choke system. This means it seamlessly integrates with a vast number of popular 20 gauge shotguns, offering a simple yet profound upgrade. Crafted by Extreme Accuracy Rifles (EAR), a brand synonymous with precision and performance in firearm accessories, this choke tube embodies their commitment to enhancing shooter capabilities. It's an internal choke, meaning it sits flush with the end of the barrel, maintaining a clean aesthetic while delivering superior ballistic performance.

This particular choke is ideal for shooters who require an extremely tight pattern. Its .570 constriction is notably tighter than a standard Full choke for a 20 gauge, positioning it firmly in the "Extra Full" or even "Super Full" category. This makes it an invaluable asset for specialized applications where every pellet counts and maximum pattern density is crucial at extended ranges. When you need to put the highest possible concentration of pellets on a small target far away, this is the tool designed to deliver.

Unpacking the ".570" Constriction: Precision for Your 20 Gauge

The .570 constriction is arguably the most defining characteristic of the EAR JPCBN20A2/570 High Voltage Rem Choke. To fully appreciate its significance, it helps to understand what this measurement means. In a 20 gauge shotgun, the bore diameter is nominally around .615 inches. A .570 constriction means that the exit diameter of the choke is a mere .570 inches, creating a substantial squeeze on the shot column. This level of constriction is designed to produce an exceptionally tight and dense pattern, far more concentrated than what you'd typically see from a standard "Full" choke.

What are the practical implications of such a tight constriction?

• Turkey Hunting Excellence: For turkey hunters, the .570 constriction is a game-changer. Turkeys present a small, vital target area (head and neck) that requires an incredibly dense pattern of pellets for a clean, ethical harvest. This choke ensures that a high percentage of your shot lands within a tight group, maximizing your chances of hitting the critical zone even at ranges up to 40 or 50 yards, depending on ammunition choice. It helps hunters confidently extend their effective range without sacrificing knockdown power.
• Specialized Hunting: Beyond turkey, this choke can be highly effective for other forms of hunting where extreme range and pinpoint accuracy are needed, such as coyotes or even some waterfowl scenarios with appropriate non-toxic shot, though its primary strength lies in its ability to concentrate small, dense shot loads.
• Target Shooting: While not for every clay target discipline, a .570 choke can be devastatingly effective for very distant or unique targets in sporting clays or trap shooting where maximum pattern retention is desired.
• Increased Pellet Count in Critical Zone: The tighter constriction ensures that more pellets remain within a smaller area downrange, leading to a higher probability of multiple pellet strikes on the target. This translates directly to more reliable knockdowns and cleaner breaks.

When considering a .570 constriction, it's vital to pair it with the right ammunition. High-quality, buffered loads or specialized turkey loads with larger, harder pellets (like #4, #5, or #6 shot) will perform exceptionally well, maintaining pattern integrity through the tight constriction. Lighter, softer loads or very small shot sizes might deform excessively, leading to less consistent patterns.

The Power of "High Voltage" Design

The "High Voltage" designation in the EAR JPCBN20A2/570 choke's name isn't just marketing; it speaks to the underlying engineering philosophy aimed at maximizing pattern efficiency and energy delivery. While the exact proprietary details of EAR's "High Voltage" internal geometry are unique to their design, it generally implies a sophisticated internal taper and finish that optimizes the way the shot column transitions from the barrel into the choke.

This advanced internal design often focuses on several key areas:

• Reduced Pellet Deformation: A smoother, more gradual internal taper, combined with a highly polished surface, minimizes the crushing and deforming of pellets as they pass through the constriction. Deformed pellets fly erratically, leading to open, inconsistent patterns. The "High Voltage" design aims to keep pellets as round and uniform as possible.
• Optimized Gas Seal: An efficient internal design ensures a superior gas seal behind the shot column. This means less gas bypasses the pellets, contributing to higher retained velocity downrange and more consistent shot patterns.
• Pattern Consistency: The ultimate goal of such precise engineering is pattern consistency. When you shoot, you want to know that each shot will produce a similar, predictable pattern. The "High Voltage" design helps achieve this by controlling the shot column more effectively, shot after shot.
• Enhanced Energy Transfer: By maintaining pellet integrity and velocity, the "High Voltage" design contributes to more effective energy transfer to the target. This translates to greater penetration and more reliable performance, especially critical for hunting applications.

This specialized internal geometry sets the EAR choke apart, contributing significantly to its ability to deliver the extremely tight and effective patterns that competitive shooters and serious hunters demand. It's a testament to EAR's dedication to pushing the boundaries of shotgun performance.

Durability Meets Stealth: The Black Nitride Finish

Beyond its ballistic performance, the EAR JPCBN20A2/570 High Voltage Rem Choke boasts a robust Black Nitride finish. This isn't just about aesthetics; Black Nitride is a highly sought-after surface treatment in the firearms industry for its exceptional properties.

Key benefits of the Black Nitride finish include:

• Superior Corrosion Resistance: Shotgun chokes are exposed to harsh conditions, including gunpowder residue, moisture, and varying temperatures. The Black Nitride finish creates an incredibly hard, corrosion-resistant surface that protects the steel from rust and environmental degradation, ensuring a long service life even with frequent use in challenging weather.
• Enhanced Wear Resistance: Nitriding significantly hardens the surface of the steel, making it highly resistant to abrasion, scratching, and wear from repeated installation/removal and the passage of thousands of shot loads. This maintains the choke's precise internal dimensions over time, which is crucial for consistent patterning.
• Reduced Friction: The slick nature of a nitrided surface can also contribute to reduced friction as shot pellets pass through, further aiding in minimizing pellet deformation and promoting smoother shot exit.
• Non-Reflective, Tactical Appearance: The deep black, non-glare finish is not only aesthetically pleasing but also practical for hunters who need to remain concealed. It won't reflect light, reducing the chance of spooking game.
• Easy Maintenance: The smooth, hard surface makes cleaning powder residue and fouling much easier, requiring less effort to keep your choke in pristine condition.

This combination of advanced ballistic engineering and a high-performance finish means the EAR choke is built not just for superior performance but for long-term reliability and rugged use in the field.

Is the EAR .570 Rem Choke Right For You? Common Questions Answered.

Many shooters ask, "How do I choose the best choke for my shotgun?" or "Will this choke fit my firearm?" Let's address some common queries to help you determine if the EAR JPCBN20A2/570 High Voltage Rem Choke is the ideal choice for your needs.

• "What's the best choke for turkey hunting with a 20 gauge?"
  For turkey hunting, especially with a 20 gauge, a super-tight constriction like the .570 is often considered optimal. It creates the dense, concentrated pattern necessary to ethically dispatch turkeys at typical hunting ranges. This EAR choke is designed precisely for that purpose, maximizing pellet count in the critical kill zone.
• "Will this choke work with my Remington shotgun?"
  Yes, if your Remington 20 gauge shotgun is designed to accept Rem Choke (Remington Arms Company Choke) interchangeable choke tubes. The "Rem Choke" system is one of the most widely adopted in the industry, making this EAR choke compatible with a vast array of Remington models and many other shotguns that utilize the Rem Choke threading standard. Always verify your shotgun's specific choke system compatibility before purchase.
• "How does this choke improve accuracy?"
  While a choke doesn't improve a shotgun's "accuracy" in the rifle sense (i.e., making a single projectile hit precisely where aimed), it dramatically improves pattern density and consistency. By keeping the shot column tighter for longer, more pellets reach the target within a smaller area. This effectively increases your "effective range" and the likelihood of achieving multiple, decisive hits on your target, which is critical for shotgun performance.
• "Is a .570 choke too tight for general hunting or clay shooting?"
  For general upland bird hunting or many clay target games (like skeet or sporting clays at closer stations), a .570 choke would likely be too tight. It delivers a very narrow pattern that requires precise aiming and limits your margin for error. Its strength lies in specialized applications where maximum pattern density at longer ranges is the primary goal. For versatility, you'd typically have a set of chokes ranging from Cylinder to Full.
• "How do I install and care for my choke tube?"
  Installation is simple. Ensure your shotgun is unloaded and pointed in a safe direction. Screw the choke tube into the muzzle end of the barrel by hand until finger-tight. Then, use a choke tube wrench (often included with shotguns or sold separately) to tighten it snugly, but do not overtighten. Over-tightening can make removal difficult and potentially damage the threads. For care, regularly remove the choke, clean threads on both the choke and barrel, and apply a light coat of gun oil or anti-seize compound to prevent seizing, especially with a high-performance choke like this that sees a lot of use.

Maximizing Performance: Tips for Using Your EAR High Voltage Choke

To truly unlock the full potential of your EAR JPCBN20A2/570 High Voltage Rem Choke, consider these essential tips:

1. Pattern Your Shotgun: This is perhaps the most crucial step. Every shotgun and choke combination performs slightly differently with various ammunition types. To understand your actual pattern density and point of impact, you must pattern your shotgun at realistic engagement ranges (e.g., 20, 30, 40 yards for turkey hunting) using the exact ammunition you intend to use. This reveals how many pellets hit within a specific target area and where the core of your pattern lands relative to your aim point.
2. Ammunition Selection: For a .570 constriction, choose premium ammunition. For turkey hunting, look for specialized turkey loads that utilize larger, harder, and often buffered lead shot (like #4, #5, #6) or tungsten-based non-toxic shot. These harder pellets resist deformation better when squeezed through the tight choke, maintaining their spherical shape and flying truer, resulting in denser patterns. Avoid cheap, unbuffered, or very soft shot for this choke, as it may produce inconsistent results.
3. Cleanliness is Key: Regularly clean your choke tube and the barrel threads. Powder residue can build up, leading to a seized choke tube if not maintained. Use a good bore solvent and a brush. Lubricating the threads with anti-seize grease or a quality gun oil before each installation is highly recommended to ensure easy removal and proper seating.
4. Practice, Practice, Practice: A premium choke tube enhances your shotgun's capabilities, but consistent shooting still relies on fundamental skills. Practice aiming, trigger control, and follow-through with your patterned setup to become proficient with the tight pattern produced by this choke.
