Building your own AR-15 can be a rewarding experience, allowing for customization and a deep understanding of your firearm. But where do you start? A complete AR-15 kit provides all the necessary components to assemble a functional rifle, saving you time and the potential headaches of sourcing individual parts. This guide explores what to look for in a complete AR-15 kit and how to choose the right one for your needs.
Understanding the Components of a Complete AR-15 Kit
A comprehensive AR-15 kit should include all the essential parts needed for assembly, typically categorized into upper and lower receiver components. Let's break down the key elements:
Lower Receiver Components:
- Lower Receiver: The heart of the AR-15, the lower receiver houses the fire control group and is considered the serialized part of the firearm. Check for quality materials and proper markings.
- Buffer Tube: This houses the buffer spring and recoil buffer, essential for the weapon's cycling. Different lengths are available depending on stock preference.
- Buffer Spring and Recoil Buffer: These work together to manage recoil. Quality buffers are crucial for reliable operation.
- Grip: Provides the handhold for the weapon. Ergonomics and comfort are key considerations.
- Trigger Assembly: This includes the trigger, hammer, and disconnector. Choose a trigger that suits your shooting style and preferences (single-stage, two-stage, etc.).
- Safety Selector: Controls the firing mode of the weapon. Ensure it operates smoothly and securely.
- Magazine Release: Allows for easy magazine changes. A smooth and reliable release is essential for quick reloads.
- Stock: Provides support for the weapon when shouldered. Different stock types (fixed, adjustable, collapsible) offer varying levels of adjustability and comfort.
Upper Receiver Components:
- Upper Receiver: This houses the barrel, bolt carrier group, and charging handle. Ensure it's well-machined and correctly assembled.
- Barrel: The barrel is a critical component influencing accuracy and performance. Caliber, length, and twist rate are essential choices, impacting the type of ammunition you can use. Common calibers include 5.56 NATO and .223 Remington.
- Bolt Carrier Group (BCG): This is the heart of the firearm’s action. High-quality BCGs are crucial for reliable operation. Choose a reputable manufacturer.
- Charging Handle: Used to manually cycle the action. Look for smooth operation and comfortable ergonomics.
- Gas Tube: Directs the gases from the barrel to the BCG.
- Handguard/Rail System: Protects the barrel and provides mounting points for accessories like optics, lasers, and lights. Different rail systems offer varying degrees of modularity.
Choosing the Right Complete AR-15 Kit: Key Considerations
Selecting the appropriate AR-15 kit involves careful consideration of several factors:
- Budget: Kits range in price significantly based on the quality and brand of components.
- Intended Use: Are you building a rifle for home defense, competition shooting, hunting, or something else? This dictates the components you prioritize (e.g., barrel length, trigger type).
- Experience Level: While complete kits simplify assembly, some mechanical aptitude is still needed. Consider your comfort level with assembling the firearm.
- Brand Reputation: Research manufacturers known for quality and reliability.
- Caliber: The most common is 5.56 NATO/.223 Remington, but others exist.
Beyond the Kit: Essential Accessories
While a complete kit provides the fundamental parts, remember that you may need additional accessories:
- Ammunition: Always source ammunition from reputable vendors and ensure it's compatible with your chosen caliber.
- Optics: A sight or scope significantly enhances accuracy and shooting capabilities.
- Cleaning Kit: Regular cleaning and maintenance are essential for firearm longevity and reliable operation.
Conclusion
Building an AR-15 from a complete kit offers a unique and engaging way to own a customized rifle. However, thorough research and careful consideration of the factors outlined above are crucial to making an informed decision and ensuring a safe and enjoyable building experience. Remember to always prioritize safety and follow all applicable laws and regulations.
