The AR-15 platform's enduring popularity stems from its modularity and customizability. At the heart of this system lies the bolt carrier group (BCG), a crucial component responsible for cycling ammunition and ensuring reliable operation. Understanding your BCG is vital, and today, we'll delve into the specifics of BCA (Bravo Company USA) bolt carrier groups, exploring their features, performance, and place within the broader AR-15 market.
What is a Bolt Carrier Group (BCG)?
Before we dive into BCA specifically, let's establish a foundational understanding. The BCG is the engine of your AR-15. It's a complex assembly containing several key parts:

- Carrier: This moves the bolt rearward during recoil and forward during the firing cycle.
- Cam Pin: This crucial component synchronizes the bolt and carrier's movements.
- Extractor: This grabs spent casings to facilitate extraction.
- Ejector: This propels the spent casing out of the firearm.
