Understanding the AR-15 Upper Receiver
The Core Components
To understand the appeal of Palmetto State Armory uppers, it’s crucial to grasp the function and components of the AR-15 upper receiver itself. Essentially, the upper receiver is the top half of the AR-15, the part responsible for firing the ammunition and cycling the action.
This upper assembly encompasses several vital elements:
- The Barrel: This is the heart of the rifle’s accuracy, the metal tube that guides the bullet. Barrel length, twist rate (the rate at which the bullet spins), and material all affect performance.
- The Bolt Carrier Group (BCG): This assembly contains the bolt, which locks the cartridge into the chamber, and the carrier, which houses the bolt and facilitates the cycling of the action. The BCG is crucial for reliability.
- The Charging Handle: Used to manually cycle the action and chamber the first round.
- The Handguard: This component protects the barrel and allows the user to grip the rifle comfortably. Handguards often feature mounting systems for accessories like optics, lights, and vertical grips.
- The Upper Receiver: The main structural component, to which all the other elements are attached. It houses the bolt carrier group and provides the foundation for the barrel and handguard.
- The Gas System: This vital component taps off gas from the fired round to cycle the action, which includes the gas block and gas tube.
By understanding these components, we see how the upper receiver fundamentally dictates the rifle’s capabilities. And when it comes to upgrading or building an AR-15, the upper is often the starting point.

Different Types of Palmetto State Armory Uppers
Variety is Key
The versatility of Palmetto State Armory uppers extends to the wide range of available configurations. This flexibility allows you to tailor your rifle to your specific needs.
- Caliber Considerations: PSA offers uppers in a variety of calibers, including the popular .223/5.56 NATO, the often-favored .300 Blackout for its subsonic capabilities, and others. For those looking for a lower-cost option, PSA provides .22LR uppers.
- Barrel Length Variations: Barrel length is another important choice. PSA provides options from short pistol lengths (under 16 inches) to carbine, mid-length, and full-length rifle barrels (16 inches or longer). Shorter barrels are great for maneuverability, while longer barrels generally offer better accuracy and velocity.
- Handguard Styles: The handguard affects the overall appearance and usability of your rifle. PSA offers uppers with a variety of handguard designs, including:
- M-LOK: This popular mounting system allows for easy attachment of accessories.
- Free-Float vs. Drop-in: Free-float handguards don’t touch the barrel, allowing for enhanced accuracy by minimizing stress on the barrel. Drop-in handguards are often a more budget-friendly option.
- Complete Uppers versus Build-Your-Own Kits: PSA provides both options:
- Complete Uppers: These uppers come pre-assembled, ready to attach to your lower receiver. They are an easy and convenient solution for those who want a straightforward build.
- Build-Your-Own Kits: PSA also sells uppers that come unassembled, giving you the chance to build it yourself. This is perfect for those who want to personalize their rifles.
Key Features and Benefits of PSA Uppers
Specific Component Details
Beyond the general types of Palmetto State Armory uppers, several individual features contribute to their overall value and performance.
