Armalite Lower Parts Kit: Your Comprehensive Guide to AR-15 Building

Understanding the Armalite Legacy

Armalite, a name synonymous with innovation, has a rich history in the firearms industry. Founded in the mid-1950s, Armalite pioneered the development of the AR-15, a design that would revolutionize rifle technology. While the company’s ownership and structure have evolved over the years, the core principles of quality and precision remain. Armalite’s enduring legacy lies in its dedication to crafting dependable firearms and components.

Armalite’s reputation for quality stems from its commitment to utilizing premium materials, rigorous quality control, and innovative design. Their commitment to excellence makes Armalite a go-to brand for many. Choosing Armalite for your AR-15 build signifies an investment in a product known for its performance and longevity. The Armalite Lower Parts Kit, in particular, embodies this ethos, providing builders with a reliable and robust foundation for their projects.

Unveiling the Core Components of an Armalite Lower Parts Kit

The Armalite Lower Parts Kit encompasses a collection of crucial components that transform a bare lower receiver into a functioning part of an AR-15. Understanding these components and their function is essential for a successful build. Let’s explore what you can expect to find within an Armalite LPK.

Trigger Essentials

At the heart of the firing process, the trigger mechanism is critical. The Armalite Lower Parts Kit will provide these key pieces:

  • The Trigger: This is the part you pull to initiate the firing sequence, physically connected to the hammer.
  • The Hammer: When released by the trigger, the hammer strikes the firing pin, which in turn, ignites the cartridge.
  • The Disconnector: This component acts as a crucial safety mechanism, preventing the hammer from following the bolt and causing an accidental double-tap.
  • Springs: Trigger, hammer, and disconnector springs work in tandem to provide the necessary force for each component. These springs play a role in returning the trigger and hammer to their starting positions after firing.
  • Pins: The trigger, hammer, and disconnector are secured by pins which allow the parts to pivot within the lower receiver. These pins must be properly aligned and secured.

The Safety Selector: Your Control Point

The safety selector, the component which allows you to choose a safe or fire mode, comes equipped with:

  • Safety Selector: This allows you to select between safe and fire settings on your rifle.
  • Safety Selector Detent and Spring: The detent and spring provide the click into the “safe” and “fire” position on the receiver.

The Bolt Catch: Ensuring Bolt Function

The bolt catch, another important component, works in conjunction with the bolt to keep it locked open after the last round is fired:

  • Bolt Catch: This component is used to hold the bolt open, and also can be used to manually lock the bolt back.
  • Bolt Catch Plunger and Spring: The plunger and spring work in concert with the bolt catch to hold the bolt open during reloading.
  • Bolt Catch Roll Pin: This pin holds the bolt catch in place.

Magazine Catch System: Secure Magazine Engagement

The magazine catch, a crucial element, facilitates secure magazine insertion and retention. You will find:

  • Magazine Catch Body: The core of the magazine catch mechanism.
  • Magazine Catch Button: The button you press to release the magazine from the lower receiver.
  • Magazine Catch Spring: This provides the necessary tension to secure the magazine.

Buffer Retainer Mechanism: The Buffer System’s Protector

The buffer retainer system keeps your buffer and spring in place:

  • Buffer Retainer: A small component that keeps the buffer and spring from moving.
  • Buffer Retainer Spring: The spring that keeps the buffer retainer in place.

Pistol Grip Attachment

The Armalite Lower Parts Kit will typically include the parts necessary for installing your pistol grip:

  • Pistol Grip Screw: This screw secures the pistol grip to the lower receiver.

Additional Small Parts

You will receive various other small parts that contribute to the overall function:

  • Trigger Guard and Roll Pin: The trigger guard helps protect the trigger, and this kit will give you the necessary roll pin.
  • Pivot Pin and Detent: Used for securing the upper and lower receiver together allowing for a pivoting movement.
  • Takedown Pin and Detent: This pin secures the upper and lower receiver together with a method of detachment and reassembly.
  • Detent Springs: Small springs that ensure the detents function correctly.

Assessing Compatibility and Key Considerations

Before starting your build, understanding compatibility is paramount. Armalite Lower Parts Kits are generally designed to fit standard AR-15 lower receivers, but verifying fitment is always a good practice.

The Armalite Lower Parts Kit is typically designed to work with a wide range of AR-15 builds. However, ensure that all components you are using are compatible before installation.

The quality of the components is critical to the performance and longevity of your build. Armalite is known for using high-quality materials.

A well-equipped workbench is vital for a successful build. You’ll need specific tools, including a punch set, a hammer, and a vise. Consider purchasing a lower receiver vise block to stabilize the lower receiver. A good quality armorer’s wrench and a torque wrench will also be invaluable.

While not overly complex, the installation process requires attention to detail. If you are new to AR-15 building, consider referencing a detailed installation guide. This will walk you through the procedures and help avoid common mistakes. Always follow safety precautions when working with firearms.

After installing the Armalite Lower Parts Kit, inspect all components. Ensure all pins are properly seated, and the trigger, safety, and bolt catch function smoothly and as intended. Test the function of the safety mechanism, the bolt catch, and the magazine release. Proper function testing is essential to ensure that your build operates safely and efficiently.

If you encounter issues, troubleshooting can often be straightforward. Problems with the trigger can sometimes be resolved by cleaning and re-lubricating the trigger mechanism.
