This video, presented by a highly authoritative source on firearms mechanics, challenges the common classification of the AR-15/M16 system as 'Direct Impingement.' Instead, it argues, based on Eugene Stoner's patents and mechanical analysis, that the AR-15 utilizes an internal piston system. True Direct Impingement rifles, like the French MAS49, are contrasted with the AR-15's design where gas acts within the bolt carrier group.
This Q&A session covers a wide range of firearms topics, from historical military hardware to modern firearm applications and manufacturing. Key discussions include the post-WW2 use of MG34 and MG42 machine guns, the distinction between prototyping and troop trials, and considerations for modern handguns chambered in historical calibers like 7.65mm French Long. The video also touches upon the least appropriate firearms for competitive shooting events, the Indian INSAS rifle, M16 follower design, and the potential use of the H&K Mk23 for home defense. Further topics include gun re-homing practices, archival projects, left-handed firearms, potential YouTube collaborations, the mechanics of locked vs. delayed blowback actions, the Borchardt as a potential bullpup PCC, challenges in contacting gun companies, the impact of COVID-19 on firearms work, Chinese arms procurement, the lack of modern revolving rifles, the state of the surplus market, French armament program suggestions, spitzer handgun bullets, French Foreign Legion arms procurement, semi-pistolgrips on lever actions, the Calico shooting, the public perception of DIY guns, and issues with reprinting firearm reference books.
