This guide demonstrates the modularity of the AR-15 platform, specifically how to change calibers by swapping upper receivers. The video highlights the ease of converting an AR-15 lower receiver, such as an Anderson Manufacturing AM-15, to fire multiple calibers including 5.56, 7.62x39, 300 Blackout, and .22LR using a conversion bolt. This process is presented as a straightforward method for shooters to adapt their platform to different ammunition types and shooting needs.
