Building your own AR-15 can be a rewarding experience, offering customization and potential cost savings. Palmetto State Armory (PSA) is a popular choice for many builders due to their wide selection of affordable parts. This guide will walk you through the process of building an AR-15 using PSA components, covering everything from selecting parts to assembling the rifle.
Choosing Your PSA AR-15 Build Kit
PSA offers various kits, from complete lowers to upper and lower receiver sets with various included components. The best kit for you depends on your experience level and desired level of customization.
Beginner-Friendly Kits:
-
Complete Lower Receivers: These are excellent starting points for beginners. PSA offers complete lowers with pre-installed fire control groups (FCGs), greatly simplifying the build process. You'll still need to assemble the upper receiver, but this significantly reduces the complexity.
-
Partial Kits: These kits include many of the necessary parts, but may require you to source additional components like the buffer tube and stock. They offer a good balance between cost and assembly challenge.
Advanced Builder Kits:
-
Lower Receiver Sets: These contain the lower receiver and necessary components but omit the FCG. This allows experienced builders greater control over their trigger selection.
-
Upper and Lower Receiver Sets: These are ideal for experienced builders looking for a comprehensive starting point. They typically contain most major components, except for the sights, optics, and sometimes the buffer tube assembly.
Key Considerations When Choosing Your Kit:
-
Your Budget: PSA offers a range of price points, allowing you to build a rifle that fits your budget. Consider what features are non-negotiable versus those you can compromise on.
-
Your Skill Level: Start with a complete lower or a simpler kit if you're a beginner. More complex kits are better suited for those with more experience.
-
Intended Use: Consider the intended purpose of your rifle (e.g., target shooting, home defense, hunting). This will influence your choice of components, such as barrel length, sights, and stock.
Essential Components in a PSA AR-15 Build
Regardless of the kit you choose, here are the key components you'll need for a complete AR-15 build:
Lower Receiver:
-
Lower Receiver: The foundation of your AR-15. PSA offers both forged and cast lower receivers. Forged receivers are generally considered more durable.
-
Fire Control Group (FCG): This is the heart of the rifle's firing mechanism. PSA offers various FCGs, from budget-friendly options to high-end triggers.
-
Buffer Tube and Castle Nut: These components house the buffer spring and buffer, contributing to the rifle's recoil system. PSA offers different buffer tube lengths and materials.
-
Pistol Grip: Provides a comfortable and secure grip. PSA offers a variety of grips in different materials and styles.
-
Stock: Attaches to the buffer tube and allows for shouldering the rifle. PSA offers different styles, from fixed stocks to adjustable stocks.
Upper Receiver:
-
Upper Receiver: The top half of the rifle, which houses the barrel and bolt carrier group.
-
Barrel: The barrel's length and twist rate significantly impact accuracy and performance. Choose a barrel length appropriate for your intended use.
-
Bolt Carrier Group (BCG): A critical component responsible for cycling ammunition. PSA offers various BCGs, including their own brand and those from other manufacturers.
-
Charging Handle: Used to manually cycle the BCG and load ammunition.
-
Gas System: The gas system regulates the flow of gas from the barrel to the BCG. Different gas systems (e.g., carbine-length, mid-length) influence the rifle's function and recoil characteristics.
-
Handguard/Rail: Protects the barrel and provides mounting points for accessories. Various handguard lengths and styles are available.
-
Sights (Optional): PSA offers various sights, from basic iron sights to more advanced options.
Assembling Your PSA AR-15
Once you've gathered your components, you can begin assembly. Numerous online resources, including videos from PSA and other reputable sources, provide detailed instructions for AR-15 assembly. Always prioritize safety and follow instructions carefully. Improper assembly can lead to malfunctions or even injury.
