What exactly is a Lower Build Kit?
The AR-15. A rifle celebrated for its modularity, versatility, and the sheer enjoyment of building your own. Whether you’re a seasoned firearms enthusiast or just beginning your journey into the world of self-built rifles, the process is undeniably rewarding. The heart of any AR-15 is the lower receiver, the serialized component that houses the trigger, hammer, and other critical parts. And while you can buy a complete lower receiver, the satisfaction of building one yourself, customizing it to your specific needs, is unparalleled. That’s where the concept of the BCM Lower Build Kit comes into play, offering a streamlined path to a high-quality, reliable AR-15 lower receiver. This article delves into the world of the BCM Lower Build Kit, exploring its features, benefits, and why it’s a top choice for builders of all levels.
Before we dive into the specifics of the BCM Lower Build Kit, let’s clarify what a lower build kit actually *is*. In essence, a lower build kit provides all the non-serialized parts you need to complete the lower receiver of your AR-15. This kit typically *doesn’t* include the lower receiver itself, which is the legally controlled, serialized component. Instead, it contains a carefully selected set of parts designed to work together seamlessly, ensuring a smooth and reliable functioning of your rifle.
These kits generally encompass a range of essential components:
- Trigger Assembly: This includes the trigger itself, the hammer, the disconnector (which prevents the hammer from following the bolt back down), and the associated pins and springs. The quality of the trigger assembly significantly impacts the feel and performance of your rifle.
- Bolt Catch: This component locks the bolt back after the last round in the magazine is fired, signaling the need for a reload.
- Bolt Catch Roll Pin: This pin secures the bolt catch in place.
- Magazine Catch Assembly: This assembly allows you to release the magazine from the rifle.
- Safety Selector: A crucial safety feature, allowing you to switch between safe and fire modes.
- Buffer Tube (If Included): Some kits include the buffer tube, which houses the buffer spring and buffer itself. If not included, you will need to procure a buffer tube separately.
- Buffer Detent and Spring: These components secure the buffer tube and prevent it from rotating.
- Takedown/Pivot Pin Detents and Springs: These springs and detents secure the takedown and pivot pins, which allow you to separate the upper and lower receivers for cleaning or maintenance.
The quality and compatibility of these components directly influence the overall reliability, performance, and longevity of your AR-15. A BCM Lower Build Kit stands out because of its commitment to providing high-quality components, ensuring that the finished product is a robust and dependable firearm.
