Understanding the AR-15 Charging Handle and Bolt Carrier: A Comprehensive Guide
The AR-15, a popular firearm among enthusiasts and professionals alike, is renowned for its modularity and reliability. Two of its most crucial components are the charging handle and the bolt carrier group. In this detailed guide, we will delve into the functions, types, and maintenance of these components, providing you with a comprehensive understanding of their importance in the AR-15 platform.
What is a Charging Handle?
The charging handle is a crucial part of the AR-15 rifle, serving as the mechanism for cycling the bolt carrier group. Its primary function is to move the bolt carrier group forward and backward, allowing for the loading and ejection of rounds. The charging handle is typically located on the right side of the rifle, but it can be swapped to the left side for left-handed shooters.
