What is a Modern Sporting Rifle (MSR)?

A Modern Sporting Rifle (MSR) is best described as a semi-automatic rifle that is designed for versatility and ease of use. The key characteristics of an MSR include its ability to accept detachable magazines, which allows for faster reloading and the capacity to hold multiple rounds, enhancing overall functionality in various shooting scenarios.

MSRs are typically built on the AR-15 platform and have become popular among hunters, sport shooters, and individuals seeking home defense options due to their modular design. This modularity enables users to customize the rifle with various accessories, such as optics, grips, and stocks, to fit their specific needs or preferences. The semi-automatic action means that the rifle can fire one round per trigger pull, with the action automatically reloading for subsequent shots, which contributes to its accessibility and ease of use for shooters of varying skill levels.
