Who Is This Essential Upgrade For?

Are you asking yourself, "What's the best way to make my Remington 870 more versatile?" or "How can I optimize my 870 for both home defense and general shooting?" This REM Arms 20-inch barrel is precisely the answer for a diverse range of Remington 870 Express owners.

• The Home Defense Enthusiast: Looking for optimal maneuverability in confined spaces? A shorter barrel significantly enhances handling within a home environment, allowing for quicker target acquisition and safer navigation around obstacles. This barrel is a primary choice for those setting up a dedicated defensive shotgun.
• The Tactical Shooter: Whether for training, competition, or tactical scenarios, the shorter length provides a compact profile, making transitions and close-quarters operations more efficient. It’s ideal for drills where speed and agility are paramount.
• The Versatile Hunter: While longer barrels are common for waterfowl or upland game, a 20-inch barrel excels in dense brush, slug hunting, or situations requiring a more compact firearm. It offers a balance of pattern density at closer ranges and improved handling.
• The Shotgun Customizer/Builder: For those who enjoy tailoring their firearms, this OEM barrel provides the perfect foundation or component for a custom 870 build, ensuring factory-level fit and finish.
• The Owner of a Worn or Damaged Barrel: If your existing barrel has seen better days, suffered damage, or simply shows significant wear from years of faithful service, this genuine REM Arms replacement restores your 870 to its original, dependable performance standards. It ensures your firearm maintains its integrity and accuracy for years to come.

This barrel addresses the core need for adaptability, allowing one shotgun to serve multiple purposes efficiently and effectively, all while maintaining the hallmark reliability of the Remington 870 platform.

Unpacking the Features: Why This 20-Inch Barrel Excels

This REM Arms R24622 OEM Replacement Barrel isn't just another accessory; it's a meticulously crafted component designed to seamlessly integrate with your Remington 870 Express, delivering specific performance advantages.

• Genuine REM Arms Accessories Quality: As an Original Equipment Manufacturer (OEM) part, this barrel is produced to the exact specifications and quality control standards as the barrel that originally came with your Remington 870. This guarantees a perfect fit, reliable function, and the unwavering performance you expect from a Remington firearm. You won't find better compatibility or long-term durability than with a true OEM component.
• Optimized 20-Inch Length: The 20-inch length strikes an optimal balance. It’s significantly shorter than typical hunting barrels (often 26-28 inches), making the shotgun much more maneuverable in tight spaces – crucial for home defense or tactical applications. Yet, it retains enough length to provide effective ballistic performance for a wide range of 12-gauge loads, including buckshot and slugs, ensuring reliable patterns at typical defensive and hunting ranges.
• 12 Gauge Compatibility: Engineered specifically for 12-gauge Remington 870 Express models, this barrel ensures correct chambering and cycling of the most popular and versatile shotgun ammunition.
• Robust Construction: Manufactured from high-quality steel, this barrel is built to withstand the rigors of repeated firing and harsh environments. It is designed for longevity, resisting corrosion and maintaining structural integrity over countless rounds, just as you would expect from a Remington factory part.
• Seamless Integration with Your Remington 870 Express: Installation is straightforward, requiring no permanent modifications to your existing 870 Express receiver. It slides directly into place and secures with the fore-end cap, making barrel swaps quick and easy. This "tool-free" exchange ability is a significant benefit for users who frequently switch between different shotgun configurations.
• Versatile Application Profile: While the 20-inch length naturally lends itself to tactical and defensive roles, its smoothbore design and typical fixed cylinder or improved cylinder choke configuration (common for this length) also make it highly effective for slug hunting at closer ranges, or even upland game and small varmints where tight patterns are not the primary concern. Its adaptability is one of its greatest assets.

Real-World Scenarios: How This Barrel Enhances Your Capabilities

Think about how you use your shotgun. Does it meet every demand? This 20-inch OEM barrel addresses common limitations and opens up new possibilities.

Scenario 1: Optimizing for Home and Personal Defense
Problem: A long hunting barrel is unwieldy and cumbersome inside a house, making it difficult to clear corners or navigate hallways safely.
Solution: Swapping to the 20-inch REM Arms barrel dramatically reduces the overall length of your shotgun, making it far more agile and controllable in close quarters. This means faster reaction times, easier weapon retention, and greater confidence when your safety depends on it. The typically wide pattern of a cylinder bore at close range is also ideal for defensive loads like buckshot.

Scenario 2: Enhancing Tactical Training and Skill Development
Problem: Practicing tactical maneuvers with an overly long shotgun can be frustrating and unrealistic for defensive applications.
Solution: The compact nature of this 20-inch barrel mirrors the dimensions of many purpose-built defensive shotguns, providing a realistic training platform. It allows for more fluid movement, improved transitions between targets, and a focus on essential tactical skills without fighting the length of the firearm.

Scenario 3: Adapting for Dense Cover Hunting (e.g., Deer with Slugs in Woods)
Problem: Carrying a 28-inch shotgun through thick brush for deer hunting can snag on branches and limit mobility, especially when stalking.
Solution: The 20-inch barrel makes your 870 far more nimble in the woods. When paired with appropriate slug ammunition, this barrel delivers excellent accuracy for deer hunting in close-to-medium ranges typical of heavily wooded areas. It’s also often preferred for still hunting where maneuverability is key.

Scenario 4: Revitalizing an Older or Heavily Used Remington 870
Problem: Your cherished Remington 870 has a barrel that's pitted, scratched, or simply worn out after decades of use, impacting its reliability or appearance.
Solution: Replacing it with a genuine REM Arms OEM barrel is like giving your shotgun a new lease on life. It restores factory performance, ensures optimal patterning, and refreshes the aesthetic of your firearm, allowing your classic 870 to continue its legacy of dependable service.

By investing in this OEM replacement barrel, you're not just buying a part; you're investing in the enhanced capability, safety, and longevity of your most reliable firearm.

The Unmatched Trust of OEM: Why Genuine REM Arms Matters

When considering an upgrade or replacement for a critical component like a shotgun barrel, the choice between aftermarket and Original Equipment Manufacturer (OEM) parts is significant. For the Remington 870 Express, choosing a genuine REM Arms Accessories OEM barrel, like this R24622, provides unparalleled advantages that directly contribute to the longevity and performance of your firearm.

• Precision Engineering: OEM parts are manufactured using the exact same blueprints, materials, and processes as the components originally installed in your shotgun. This ensures perfect fitment, crucial for barrel alignment, secure lock-up, and consistent performance. Aftermarket parts, while sometimes good, can vary in their tolerances.
• Material Integrity: REM Arms, as the direct lineage of Remington, adheres to stringent material specifications. The steel used in these barrels is selected for its specific metallurgical properties, ensuring optimal strength, heat resistance, and corrosion resistance – factors critical for safety and durability over thousands of rounds.
• Quality Control: Every genuine REM Arms accessory undergoes rigorous quality control checks. This meticulous inspection process minimizes defects and ensures that each barrel meets the high standards synonymous with the Remington brand. This translates to fewer potential issues down the line and greater peace of mind for the user.
• Maintaining Value: Using OEM parts helps maintain the original integrity and potential resale value of your Remington 870 Express. Collectors and discerning buyers often value firearms that feature original factory components.
• Uncompromised Reliability: The legendary reliability of the Remington 870 is built on the synergy of its original components. By using an OEM replacement barrel, you ensure that your shotgun continues to operate with the same legendary dependability it was designed for, round after round, year after year.

Don't compromise on the heart of your shotgun. When you choose a REM Arms OEM replacement barrel, you're choosing the highest standard of quality and ensuring your Remington 870 performs exactly as it was intended.

Installation and Compatibility Considerations

One of the greatest appeals of the Remington 870 platform is its modularity, particularly when it comes to barrel changes. Swapping barrels on an 870 Express is a simple process that typically requires no special tools and can be done in minutes.

1. Safety First: Always ensure your shotgun is unloaded. Visually and physically check the chamber and magazine tube to confirm there is no ammunition present. Remove any ammunition from the area.
2. Remove the Fore-end Cap: Unscrew the magazine cap (or fore-end cap) located at the front of the magazine tube.
3. Slide Off the Old Barrel: Gently pull the old barrel forward and off the magazine tube and receiver. It should slide off with minimal effort.
4. Install the New Barrel: Slide the new REM Arms 20-inch barrel onto the magazine tube, ensuring the barrel lug aligns correctly with the action bars. Push it firmly back into the receiver until it seats properly.
5. Replace the Fore-end Cap: Screw the magazine cap back onto the magazine tube, hand-tightening it firmly to secure the barrel.

Compatibility Note: This barrel is specifically designed for the Remington 870 Express 12 Gauge. While many 870 models share similar designs, ensure your firearm is a 12-gauge 870 Express for guaranteed compatibility. Always confirm your specific model's requirements if unsure.

Essential Care and Maintenance for Your New Barrel

To ensure your REM Arms 20-inch barrel provides decades of reliable service, proper cleaning and maintenance are crucial.

• Routine Cleaning: After each use, especially after firing, clean the barrel bore to remove powder residue, lead/wad fouling, and any moisture. Use a quality bore cleaner, a bore brush (bronze or nylon), and cleaning patches.
• External Care: Wipe down the exterior of the barrel with a lightly oiled cloth to prevent rust and corrosion. Pay attention to areas that might be exposed to moisture or fingerprints.
• Storage: Store your shotgun and barrel in a cool, dry place, ideally in a gun safe or cabinet, to protect it from humidity and environmental damage. Consider using a silicone-treated gun sock for added protection.
• Inspection: Periodically inspect the barrel for any signs of wear, pitting, or damage. Early detection can prevent more significant issues.

By adhering to these simple maintenance practices, your new REM Arms OEM barrel will maintain its performance and appearance for years to come, truly making your Remington 870 Express a versatile and long-lasting asset.

Frequently Asked Questions about the Remington 870 Express 20" Barrel

Many users have common questions when considering a barrel replacement or upgrade for their Remington 870. Here are some of the most frequently asked, along with expert answers:

Q1: Is this barrel suitable for slug ammunition?
A1: Yes, a 20-inch smoothbore barrel (which this R24622 typically is) is very effective for shooting slugs, especially at ranges commonly encountered in dense brush hunting or defensive scenarios. For optimal accuracy with slugs, particularly beyond 50-75 yards, some shooters prefer a barrel with rifle sights or a dedicated rifled slug barrel. However, for general use and shorter distances, this barrel performs admirably with slugs.

Q2: Can I use this barrel on an older Wingmaster model, or just the Express?
A2: While many 870 barrels are interchangeable between various models (Wingmaster, Express, Police, etc.) of the same gauge, this specific REM Arms R24622 barrel is marketed and designed as an OEM replacement for the Remington 870 Express 12 Gauge. Slight differences in finish or small tolerances might exist, but generally, 12 gauge 870 barrels are cross-compatible if the magazine tube length and fore-end fit are correct. Always confirm fitment for older or specific models.

Q3: What kind of choke does this 20-inch barrel typically have?
A3: The Remington 870 Express 20-inch OEM replacement barrels (like the R24622) are most commonly produced with a fixed Cylinder Bore choke, or sometimes an Improved Cylinder. This means there is no constriction (cylinder) or very minimal constriction (improved cylinder) at the muzzle. This wide-open choke is ideal for defensive loads like buckshot, offering a wide pattern at close range, and for shooting slugs. It's generally not designed for long-range bird hunting where tighter patterns are needed.

Q4: Will I lose significant accuracy or range with a shorter barrel?
A4: For defensive applications, the 20-inch barrel offers more than enough range and accuracy for buckshot or slugs within typical engagement distances (0-50 yards). For hunting, it's excellent for close-range slug work or in dense cover. While longer barrels generally provide a slight velocity increase and can allow for tighter patterns with shot, the 20-inch barrel is a highly effective and practical length for many applications where maneuverability is paramount. The perceived "loss" of range is often overstated for the intended use cases of a compact shotgun.

Q5: Is this a genuine Remington part, or an aftermarket clone?
A5: This is a Genuine REM Arms Accessories OEM Replacement Barrel. REM Arms is the direct successor and current manufacturer responsible for Remington firearms and parts. Choosing an OEM part ensures you are getting a product made to the exact specifications and quality standards as the original factory component, guaranteeing perfect fit, function, and reliability.
