Introduction
Are you looking to extend the effective range of your AR-15 and unlock its full potential? Do you dream of consistently hitting targets at distances that once seemed unattainable? The world of AR-15 customization offers a vast array of options, and one of the most impactful is the upper receiver. A crucial component for accuracy and performance, the upper receiver houses the barrel, bolt carrier group, and other vital parts. If you’re aiming to reach out and touch targets further downrange, then a PSA 20 inch upper might be the perfect upgrade for your AR-15.
This article will delve into the features, benefits, and considerations of PSA 20 inch uppers, helping you determine if this component is the right choice for your AR-15 build. We’ll explore what makes these uppers stand out, and how they can transform your shooting experience.
What is a PSA 20 Inch Upper?
Understanding the core component, the upper receiver, is fundamental to building or upgrading an AR-15. The PSA 20 inch upper is a complete assembly, essentially the top half of your rifle (minus the lower receiver, which includes the trigger, magazine well, and stock). It typically includes the following key components:
Barrel
The heart of any AR-15 upper is the barrel. The PSA 20 inch upper is distinguished by its twenty-inch long barrel, a significant length compared to common AR-15 barrel sizes. This longer barrel is the cornerstone of the upper’s increased potential for accuracy and range. The barrel is rifled internally, giving the bullet a spin that stabilizes it in flight. The profile of the barrel (e.g., Government profile, HBAR, etc.) influences its weight and balance, impacting how the rifle handles.
Bolt Carrier Group and Charging Handle
A critical component housed within the upper is the bolt carrier group, or BCG. The BCG is responsible for extracting spent casings, chambering new rounds, and locking the bolt into battery for firing. PSA typically provides high-quality BCGs with their uppers, often featuring durable materials and coatings like nitride or chrome, which enhance corrosion resistance and overall reliability. The BCG is a workhorse, and a reliable one is essential for a functioning AR-15.
Handguard
Attached to the barrel is the handguard, which protects the shooter’s hands from the heat generated by the barrel during firing. The handguard also provides mounting points for accessories like optics, lights, lasers, and foregrips. PSA 20 inch uppers come with various handguard options, allowing for customization to fit different shooting styles and preferences. These can range from free-float designs for enhanced accuracy to those with M-LOK or KeyMod attachment points for accessory mounting. The choice of handguard is critical to both the feel and functionality of your rifle.
Other Components
The upper also includes the charging handle, used to manually cycle the action and chamber the first round. The charging handle connects with the BCG and allows the shooter to bring the action to the ready state, allowing the BCG to move back and forth. The receiver also includes the forward assist, a button that can be used to help close the bolt in the case of malfunctions.
The gas system, a critical part of the AR-15’s operating mechanism, is typically designed for optimal function. The gas block directs gas from the fired round through a gas tube, which then pushes the bolt carrier group back to cycle the action. This complex system is vital to allow a proper reloading cycle, and is an important factor in the reliability of the upper.
Benefits of a PSA 20 Inch Upper
The benefits of choosing a PSA 20 inch upper for your AR-15 are numerous and revolve around the increased ballistic performance afforded by the longer barrel.
Accuracy
The primary advantage of the longer barrel is the potential for improved accuracy. The longer the barrel, the more time the bullet spends inside, allowing for more consistent acceleration and increased stability. This translates to tighter shot groupings and enhanced precision at extended ranges. A PSA 20 inch upper is a solid platform for shooting at greater distances.
Velocity
With a twenty-inch barrel, the bullet gains increased muzzle velocity. Higher muzzle velocity leads to a flatter trajectory, meaning the bullet drops less over distance. This simplifies holdover calculations and makes it easier to hit targets at varying ranges. It also provides more energy downrange. The extra energy can improve terminal performance, especially on heavier targets.
Applications
The PSA 20 inch upper is well-suited for various shooting applications. Whether you’re a target shooter aiming for precision, a varmint hunter needing effective range, or simply enjoy the challenge of shooting at distance, the benefits of this setup are apparent. They are often seen in competition settings.
Value
The value proposition offered by Palmetto State Armory is often a deciding factor for many AR-15 enthusiasts. PSA is known for offering high-quality components at competitive prices. A PSA 20 inch upper provides exceptional value, giving shooters access to enhanced performance without breaking the bank. For those looking to build an AR-15 on a budget, PSA uppers present an attractive option.
Considerations Before Buying
While a PSA 20 inch upper can be highly beneficial, it’s important to consider a few factors before making a purchase.
Intended Use
The twenty-inch barrel is ideal for long-range shooting, it’s not necessarily the best choice for close-quarters combat (CQB) or situations where maneuverability is critical. The longer barrel adds weight and length to the rifle, which can make it less comfortable to handle in confined spaces.
Weight and Balance
The longer barrel influences the overall weight and balance of the rifle. The weight of the barrel will be somewhat different with this model, so it is important to consider how this change will affect handling. Handling can take some getting used to, depending on your preferred style.
Accessories
Before buying, consider what accessories you intend to add, such as optics. You will need to provide your own optic scope to get the best performance, since the upper doesn’t include it. Proper sight alignment is important, so consider mounting methods to optimize its position.
Compatibility
It is important to verify that your lower receiver is compatible with the upper receiver. Standard AR-15 lower receivers are generally compatible, but double-checking ensures a seamless fit and function. You’ll also need magazines, and you’ll need to make sure you have the right ammunition.
Installation and Maintenance
Once you’ve acquired a PSA 20 inch upper, proper installation and maintenance are critical for optimal performance and safety. Follow all manufacturer’s instructions and guidelines. Regular cleaning and lubrication will help to maintain its reliability and accuracy.

Different handguard options are often available. Some may have full-length Picatinny rails for maximum accessory mounting flexibility, while others may incorporate M-LOK or KeyMod systems for streamlined accessory attachment.
Materials
Materials used in the construction, such as the choice of barrel steel and upper receiver finish, vary across models. Options might include chrome moly steel for robust performance or stainless steel for enhanced corrosion resistance.
Performance Expectations
Performance with a PSA 20 inch upper can be excellent, but it’s essential to manage expectations. Depending on the ammunition used and the shooter’s skill, typical groupings at 100 yards can often be in the 1-2 inch range.
Accuracy Testing
Testing the accuracy of your upper is part of the fun. The best way to do this is at a shooting range. Use a stable rest, such as a bench or a bipod, to minimize the influence of shooter error. Shoot groups of five to ten rounds to get a good measure of consistency. Consider various loads to see which one performs best with your rifle.
Typical Uses
The versatility of a PSA 20 inch upper means it’s suitable for many scenarios. It’s an effective tool for target practice, it’s excellent for longer ranges at competition events, and it can be used for hunting varmints where extended range is required.
