This video delves into the complexities of firearm gas systems, focusing specifically on the BFG 50A MKII. The creator highlights potential "gotchas" that might not be immediately apparent, offering unique insights not commonly found elsewhere. The video is concise, taking approximately 4 minutes to explore these technical aspects of the firearm's operation.
This video from Brownells Gun Tech™ explains the concept of 'dwell time' in AR-15 firearms. It details how the duration that combustion gases act on the operating system is crucial for diagnosing cycling malfunctions and selecting the appropriate gas system for AR-15 builds. The video highlights that gas system length (Pistol, Carbine, Mid-Length, Rifle) is a primary indicator of dwell time, with shorter systems generally experiencing higher gas pressure due to the gas port being closer to the chamber.
