This guide provides an overview of the Gabbet-Fairfax Mars Pistol's unique mechanical features, as explained by Ian McCollum on Forgotten Weapons. It covers the four-lug rotating bolt, the unconventional magazine feeding system that extracts cartridges rearward, and the single-action-only operation. The video highlights the pistol's historical significance as a powerful self-loading pistol and its complex, albeit functional, operating cycle.

Ian McCollum of Forgotten Weapons details the RP-46, a belt-fed adaptation of the Soviet DPM machine gun. The video explains the unique drop-in belt-feed adapter, its operation via the bolt handle, and the internal mechanisms for cartridge extraction and chambering. Despite its innovative design, the RP-46 is noted as a rare firearm.

This video provides a detailed breakdown of how a lever action rifle functions, using a 3D rendering for clarity. It explains the mechanics of the lever, bolt, hammer, and firing pin during the firing cycle, from chambering a round to extraction and ejection. The explanation covers the process of cocking the hammer and igniting the primer, offering a clear understanding of the internal workings of this classic firearm type.

This video demonstrates a critical quality control check for AR-15 bolt carrier groups: the bolt face diameter. Using a specialized notched gauge, the instructor highlights how undersized bolt faces can lead to cartridge base wedging, preventing clean ejection. Several popular manufacturers' BCGs are shown failing this check, emphasizing the importance of verifying this spec, especially with certain ammunition types.

This video reviews the Grip-N-Pull bullet puller, detailing its operation and effectiveness across various calibers. While convenient for quick pulls, the instructor notes challenges with slippage, particularly in smaller calibers, and the physical effort required. He compares it to kinetic and cam-lock pullers, highlighting the Grip-N-Pull's place for occasional use despite its drawbacks and price point.

This video from Brownells demonstrates the use of a .223 broken shell extractor. The tool is designed to remove damaged or stuck cartridge cases from the chamber of a firearm, which is a common problem gun owners may encounter.
