What is a BCG?
The BCG, or Bolt Carrier Group, is a critical component of the AR-10 rifle. It is responsible for the operation of the firearm, including feeding, extracting, and ejection of ammunition. The BCG consists of several parts, each playing a crucial role in the rifle’s functionality.
Parts Included in the AR-10 BCG Parts Kit
The AR-10 BCG parts kit typically includes the following components:
| Part | Description |
|---|---|
| Bolt Carrier | The bolt carrier is the main component of the BCG, housing the firing pin, extractor, and ejector. It moves back and forth during the firing cycle. |
| Bolt | The bolt is attached to the bolt carrier and contains the rifling, which guides the bullet down the barrel. It also houses the firing pin and extractor/ejector. |
| Extractor | The extractor is responsible for pulling the cartridge case out of the chamber after the bullet is fired. It is attached to the bolt and operates in conjunction with the ejector. |
| Ejector | The ejector pushes the cartridge case out of the rifle after the bullet is fired. It is attached to the bolt carrier and operates in conjunction with the extractor. |
| Chamber | The chamber is the area in the barrel where the cartridge case is held. It is part of the bolt and is responsible for holding the cartridge case in place during the firing cycle. |
| Gas Key | The gas key is a metal plate that connects the bolt carrier to the upper receiver. It allows the gas to flow from the barrel into the bolt carrier, which in turn cycles the action of the rifle. |
