Palmetto State Armory (PSA) has become a popular choice for budget-conscious and experienced builders alike, offering a wide array of AR-15 build kits. But with so many options available, choosing the right kit can feel overwhelming. This comprehensive guide will break down everything you need to know about PSA build kits, helping you make an informed decision.
Understanding PSA Build Kits: What's Included?
PSA build kits typically include the essential components needed to assemble a complete AR-15 rifle. However, the exact contents vary depending on the specific kit. Generally, you can expect to find:
- Lower Receiver: The heart of the AR-15, containing the serial number and fire control group. PSA often offers stripped lowers, requiring further assembly.
- Upper Receiver: Houses the barrel, bolt carrier group, and charging handle. Kits may include a complete upper receiver group or separate components.
- Barrel: The barrel determines the caliber and accuracy of your rifle. PSA kits offer various barrel lengths and profiles.
- Bolt Carrier Group (BCG): A critical component responsible for cycling the ammunition. PSA uses both their own manufactured BCGs and those from reputable third-party manufacturers.
- Charging Handle: Used to manually cycle the bolt carrier group.
- Gas System Components: Depending on the kit, this may include the gas tube and gas block.
- Handguard: Protects the barrel and offers a mounting point for accessories. The style and material (e.g., M-LOK, KeyMod) will vary.
Important Note: Most PSA build kits do not include sights, a stock, pistol grip, or buffer tube assembly. These are typically purchased separately.
Choosing the Right PSA Build Kit: Factors to Consider
Selecting the perfect PSA build kit involves careful consideration of several factors:
1. Caliber:
The most fundamental decision is the caliber of your AR-15. PSA offers kits in various calibers, including:
- 5.56 NATO/.223 Remington: The most common and readily available caliber.
- .300 Blackout: A popular subsonic round suitable for suppressed shooting.
- 6.5 Grendel: Known for its longer range and accuracy.
Choose the caliber that best suits your intended use.
2. Barrel Length:
Barrel length significantly affects accuracy, velocity, and overall weight. Shorter barrels are generally lighter and more maneuverable but may sacrifice some accuracy and velocity. Longer barrels offer increased accuracy and velocity but add weight. Common barrel lengths offered by PSA include:
- 10.5": Compact and ideal for close-quarters combat (CQB).
- 16": A versatile and popular choice for various applications.
- 20": Best for long-range shooting, offering improved accuracy and velocity.
3. Budget:
PSA build kits span a wide range of price points. Determine your budget before browsing to avoid buyer's remorse. Remember that additional accessories will increase the overall cost.
4. Experience Level:
While PSA kits are generally considered user-friendly, building an AR-15 requires some mechanical aptitude and patience. Beginners might find it helpful to consult online resources or videos.
Beyond the Kit: Essential Accessories
Once you've chosen your PSA build kit, you'll need to purchase several additional components to complete your AR-15:
- Lower Parts Kit (LPK): Contains the trigger, hammer, safety selector, and other essential internal components for the lower receiver.
- Buffer Tube Assembly: Includes the buffer tube, buffer spring, and buffer.
- Stock: The rear section of the rifle, providing a shoulder rest.
- Pistol Grip: Offers a comfortable and secure grip.
- Sights or Optic: Essential for aiming your rifle accurately.
Conclusion: Building Your AR-15 with PSA
Building an AR-15 from a PSA kit can be a rewarding experience, offering significant cost savings compared to purchasing a complete rifle. By carefully considering the factors outlined above and doing thorough research, you can select the perfect PSA build kit to match your needs and budget. Remember safety is paramount; always follow proper firearm handling procedures and consult qualified professionals if you have any doubts.
