Ar Lower Assembly: A Comprehensive Guide
When it comes to the world of firearms, the lower assembly is a crucial component that holds the entire firearm together. In this article, we will delve into the intricacies of the AR lower assembly, exploring its various aspects, functions, and the importance it plays in the firearm’s performance. So, let’s get started with an in-depth look at the AR lower assembly.
Understanding the AR Lower Assembly
The AR lower assembly is the foundation of an AR-15 rifle. It is the part that houses the magazine, trigger, hammer, and safety mechanisms. The lower assembly is typically made of aluminum or polymer and is the part that is often customized by firearm enthusiasts. It is important to note that the lower assembly is the only part of the firearm that requires registration in some countries due to its potential for conversion into an unregistered firearm.
Components of the AR Lower Assembly
Let’s take a closer look at the components that make up the AR lower assembly:
| Component | Description |
|---|---|
| Receiver | The receiver is the main structural component of the lower assembly. It houses the trigger group, magazine release, and safety selector. The receiver is also where the serial number is typically located. |
| Trigger Group | The trigger group includes the trigger, hammer, and safety selector. It is responsible for the firing of the firearm when the trigger is pulled. |
| Magazine Release | The magazine release is a lever that allows the user to remove and replace the magazine. It is typically located on the left side of the lower assembly. |
| Safety Selector | The safety selector allows the user to switch between the “safe” and “fire” positions. When in the “safe” position, the hammer is locked and the firearm cannot fire. |
These components work together to ensure the firearm operates smoothly and safely.
