Essentially, the 20 inch barrel maximizes the 5.56 NATO cartridge’s potential, ensuring optimal performance.

Accuracy

The longer barrel length improves accuracy by providing a longer sight radius and more stable bullet trajectory. This means you can hit your target more consistently, even at extended ranges. A user on Reddit shared their experience with a 20 inch upper, noting that it “tightens up nice with the good stuff” at 100 yards.

Velocity

A 20 inch barrel allows the bullet to reach higher velocities compared to shorter barrels. This increased velocity translates to better terminal performance and flatter shooting, making it easier to hit distant targets. While a 16-inch barrel provides a velocity of around 2,940 FPS with Federal 62-grain 5.56 ammo, a 20 inch barrel adds approximately 120 FPS, giving you that extra edge.

Historical Significance

The 20 inch barrel length has historical roots in the M16 rifle, used extensively by the military. This gives it a nostalgic appeal for those who appreciate classic firearm designs. The retro styling of options like the Stag Retro 20in Upper resonates with enthusiasts looking for a piece of history in their modern builds.

Versatility

Whether you prefer a classic A1-A2 style or a more contemporary design, there’s a 20 inch upper to suit your preferences. For instance, options like the Aero Precision 20in Upper offer a classic M16 design, while the White Oak 20in SPR Upper provides a modern, high-end build.

Next, we’ll explore the Key Features to Look for in a 20 Inch AR-15 Upper, helping you make an informed decision when selecting the perfect upper for your needs.

Key Features to Look for in a 20 Inch AR-15 Upper

When choosing a 20 inch AR-15 upper, several key features can significantly impact performance, durability, and overall satisfaction. Let’s break down the most crucial aspects to consider:

Barrel Material

The barrel is the heart of your AR-15, and its material directly affects accuracy and longevity. High-quality barrels are typically made from 4150 Chrome Moly Vanadium steel, known for its strength and heat resistance. For improved corrosion resistance and easier cleaning, look for barrels with a Black Nitride finish.

Handguard Type

The handguard is essential for mounting accessories like optics, lights, and grips. There are two popular systems to consider:

• KeyMod: Lightweight and modular, allowing for easy attachment of accessories.
• M-LOK: Similar to KeyMod but offers more versatility and a slightly more secure attachment.

Free-floating handguards are also worth considering as they do not touch the barrel, reducing barrel flex and improving accuracy.

Gas System

The gas system length directly affects the rifle’s recoil and reliability. For a 20 inch barrel, a rifle-length gas system is ideal. It offers a smoother recoil impulse and is generally more reliable than shorter gas systems.

Compatibility

Ensure that the upper you choose is compatible with your lower receiver and other components. Compatibility can vary based on the make and model of your AR-15.

• Upper Receiver: Must fit your lower receiver without issues.
• Bolt Carrier Group (BCG): Ensure the BCG is compatible with the upper.
• Charging Handle: Should be compatible with both the upper and BCG.

Summary Table of Key Features

Feature	Description
Barrel Material	4150 Chrome Moly Vanadium steel with Black Nitride finish for durability and corrosion resistance
Handguard Type	KeyMod or M-LOK systems for accessory attachment; free-floating for improved accuracy
Gas System	Rifle-length for smoother recoil and better reliability
Compatibility	Ensure fit with lower receiver, BCG, and charging handle

By focusing on these key features—barrel material, handguard type, gas system, and compatibility—you can ensure that your 20 inch AR-15 upper will meet your needs for performance, reliability, and customization.

Next, we’ll discuss the pros and cons of building versus buying a complete 20 inch AR-15 upper, helping you decide which route is best for you.

Building vs. Buying a Complete 20 Inch AR-15 Upper

When it comes to acquiring a 20 inch AR-15 upper, you have two main options: building one yourself or buying a complete upper. Both routes have their own set of advantages and disadvantages. Let’s break them down to help you make an informed decision.

Pros and Cons

Building Your Own Upper

Pros:
– Customization: You have complete control over every component, from the barrel to the handguard. This allows you to tailor the upper to your exact preferences.
– Cost-Effectiveness: Building can often be cheaper than buying a complete upper, especially if you shop for deals and discounts.
– Skill Development: Assembling your own upper teaches you how each part functions, which can be invaluable for future troubleshooting and maintenance.

Cons:
– Time-Consuming: Building an upper can take a significant amount of time, especially if you’re new to the process.
– Tools Required: You’ll need specific tools like a torque wrench and headspace gauges, which can add to the initial cost.
– Potential for Errors: If not assembled correctly, the upper can have issues with reliability and performance.

Buying a Complete Upper

Pros:
– Convenience: A complete upper comes fully assembled and ready to attach to your lower receiver. This saves you time and effort.
– Reliability: Manufacturers often test their complete uppers for quality and reliability, giving you peace of mind.
– Warranty: Many complete uppers come with a warranty, offering protection against defects and issues.

Cons:
– Limited Customization: You’re limited to the components chosen by the manufacturer, which may not meet all your preferences.
– Higher Initial Cost: Complete uppers can be more expensive upfront compared to sourcing individual parts.

Customization

Building your own upper allows for unparalleled customization. You can choose everything from the barrel material to the handguard type, ensuring that your upper meets your specific needs. For example, you might opt for a free-floating handguard to improve accuracy or a rifle-length gas system for smoother recoil.

Cost

Cost is a significant factor to consider. Building your own upper can be more cost-effective if you find deals on individual parts. However, this can be offset by the initial investment in tools. On the other hand, buying a complete upper may have a higher upfront cost but saves you time and effort.

Ease of Assembly

If you’re new to firearms, the thought of assembling an upper can be daunting. However, with the right tools and guides, it can be a rewarding experience. Many enthusiasts recommend starting with a complete upper if you’re unsure, and then gradually building your own as you become more comfortable.

Frequently Asked Questions about 20 Inch AR-15 Uppers

What are the benefits of a 20 inch barrel?

A 20 inch barrel offers several advantages:

Accuracy: The longer barrel length provides a longer sight radius, which improves accuracy. The increased distance between the front and rear sights makes it easier to aim precisely.

Range: A 20 inch barrel allows for higher muzzle velocity. This means the bullet travels faster and maintains its trajectory better over longer distances. This is particularly important for long-range shooting and hunting.

Historical Use: The 20 inch barrel is a classic configuration, used extensively in military rifles like the M16. This historical significance can be appealing for enthusiasts who appreciate traditional designs.

How do I choose the right handguard?

Choosing the right handguard involves considering several factors:

Quad Rail vs. M-LOK:

• Quad Rail: Offers multiple attachment points for accessories like lights, lasers, and grips. However, it can be heavier and bulkier.
• M-LOK: Provides a more streamlined and lightweight design. It allows for modular accessory attachment while keeping the handguard slim.

Weight Considerations: The weight of the handguard can affect the overall balance and handling of your rifle. Free-floating handguards are popular for their accuracy and lighter weight, but make sure to choose one that fits your needs.

Can I convert my existing AR-15 to a 20 inch upper?

Yes, you can convert your existing AR-15 to a 20 inch upper. Here’s how:

Compatibility: Ensure that the new upper is compatible with your lower receiver. Most AR-15 parts are designed to be interchangeable, but it’s always good to double-check.

Head Spacing: Proper head spacing is crucial for safety and reliability. When swapping barrels, you may need to check the head spacing using gauges to ensure everything is aligned correctly.

Tools Needed: Converting to a 20 inch upper requires some specific tools:
– Torque Wrench: To properly tighten the barrel nut.
– Headspace Gauges: To check the alignment and spacing.
– Armorer’s Wrench: For various assembly tasks.
