Finding the right Armalite lower parts kit can be daunting, especially for first-time builders or those unfamiliar with the nuances of AR-15 components. This guide dives deep into the world of Armalite lower parts kits, covering everything from what's included to factors to consider when making your purchase. We'll equip you with the knowledge to confidently choose the perfect kit for your next build.
What is an Armalite Lower Parts Kit?
An Armalite lower parts kit contains all the essential components needed to complete the lower receiver of an AR-15 style rifle, excluding the lower receiver itself. The lower receiver is the serialized part of the firearm and is usually purchased separately. The kit provides all the internal mechanisms that allow the rifle to function, ensuring a smooth and reliable shooting experience.
Components Typically Included in an Armalite Lower Parts Kit
A standard Armalite lower parts kit usually includes the following components:
- Disconnector: This crucial part prevents the firearm from firing more than one round with a single trigger pull.
- Hammer: Strikes the firing pin, igniting the primer in the cartridge.
- Hammer Pin (often two): Securely holds the hammer in place.
- Trigger: The component that initiates the firing sequence.
- Trigger Pin (often two): Securely holds the trigger and disconnector in place.
- Bolt Catch: A lever that locks the bolt to the rear after the last round is fired.
- Bolt Catch Roller Pin: Secures the bolt catch.
- Safety Selector: Allows the user to switch between safe, semi-automatic, and (in some cases) burst modes.
- Safety Detent Pin: Holds the safety selector in place.
- Ejector: Ejects the spent casing from the firearm.
- Ejector Pin: Secures the ejector.
- Magazine Catch: A button that releases the magazine from the lower receiver.
- Magazine Catch Spring and Roll Pin: Holds the magazine catch securely.
- Grip Screw: Secures the pistol grip to the lower receiver.
Note: Some kits might include additional components, such as a takedown pin detent and spring, while others may require purchasing these separately. Always double-check the kit's contents before purchasing.
Factors to Consider When Choosing an Armalite Lower Parts Kit
Several key factors influence your choice of Armalite lower parts kit:
1. Material Quality:
Look for kits made from high-quality materials like hardened steel and durable polymers. These materials ensure the longevity and reliability of your components. Cheap materials can lead to malfunctions and premature wear.
2. Brand Reputation:
Reputable brands invest in quality control and testing, resulting in more reliable and consistent performance. Research brands and read reviews before committing to a purchase.
3. Price Point:
While higher-priced kits often offer superior quality and features, it's essential to find a balance between cost and performance that suits your budget.
4. Specific Needs:
Consider your rifle's intended use and purpose. For example, a kit designed for a competition rifle might differ from one intended for defensive use.
Beyond the Kit: Essential Considerations for Your AR-15 Build
Remember that the lower parts kit is only one part of building a complete AR-15. You will also need:
- Lower Receiver: The legally serialized part of the firearm.
- Upper Receiver: Houses the barrel and other upper components.
- Buffer Tube: Houses the buffer spring and buffer weight.
- Pistol Grip: Provides a comfortable and secure grip.
- Stock: Provides a stable platform for aiming and shooting.
Investing time in researching and selecting the right components will ensure a well-functioning and reliable firearm.
