AR Pistol Considerations
This video explores AR pistol reliability, specifically how different ammunition types can affect function. It demonstrates that steel-cased ammunition, potentially with lower pressure, can lead to short-stroking issues where the bolt doesn't cycle fully. The instructor highlights that tuning the buffer spring, buffer weight, and gas system is crucial for reliable operation, especially with softer-shooting ammunition. A purpose-built AR pistol from Double Star is shown to perform better than a pieced-together one, validating the integrated design approach.
