AK-50 V3 Update - The Parts Are DONE

Mark Serbu discusses the challenges of manufacturing BFG 50A bolt carriers and other components, detailing a complex SolidWorks modeling process for a helical cam pin cutout. He also provides a public service announcement regarding firing pin retention in the BFG 50A and offers advice on removing a peened firing pin retainer. The video highlights the outsourcing of parts like bolt carriers and extractors due to production demands.

This guide details the design and assembly considerations for the AK-50 V3 prototype, drawing on Brandon Herrera's expertise as the lead designer. It covers critical aspects like receiver construction, recoil management, gas system tuning, and weight reduction techniques, highlighting the engineering challenges of chambering a .50 BMG round in an AK-platform rifle.

This guide details the assembly and inspection of the AK-50 V3 prototype, focusing on its 3D-printed mock-up. It covers key design elements such as the PKM-inspired stock, hinged piston, helical lockup, and the distinction between .50 BMG and .50 Beowulf calibers. The process emphasizes verifying CAD files and functional fitment before proceeding to metal machining, highlighting the iterative nature of firearm development.

This entry details the Haenel StG45(H) prototype, a simplified version of the Sturmgewehr designed for cost-effective mass production using sheet metal stampings. Key modifications include a top-mounted recoil spring and a simplified bolt carrier assembly, though its functional performance remains undocumented. The analysis highlights the innovative, albeit unproven, manufacturing techniques employed in this historical firearm design.

This guide details the installation of the Krebs Custom Left-Side Charging Handle Kit for AKM-pattern rifles. The modification is presented as a tool-less, non-permanent, and reversible upgrade, taking approximately 20 seconds. It enhances ergonomics for competitive shooting by allowing faster reloads and malfunction clearing without breaking the firing grip. The kit utilizes a modified WBP Polish bolt carrier designed for thick-stem AKM bolts.

Mark Serbu discusses the development of a piston system for the BFG-50A, moving away from direct impingement due to alignment issues. He highlights the challenges of a stuck, corroded original piston system and introduces a new, smaller piston design. The video also showcases unusual bolt carrier bounce and hammer behavior observed during testing of the piston system, even without a return spring.

Brandon Herrera, leveraging his expertise in firearms and historical testing, conducts a 'backyard science' experiment to test the JFK 'magic bullet' theory using a 6.5 Carcano. The video details the process of firing the rifle into ballistic dummies and water jugs to compare bullet deformation, offering insights into terminal ballistics and the complexities of the assassination's ballistics. Herrera's high authority in the firearms community is evident through his technical approach and knowledge of historical firearms and forensic evidence.

This video provides an expert-level look at the Pedersoli Baby Philadelphia Derringer, the type of firearm used by John Wilkes Booth to assassinate Abraham Lincoln. Brandon Herrera, demonstrating high authority and technical expertise, details the loading process for this black powder pistol and conducts ballistic tests using a beverage can and a ballistic dummy. The analysis includes high-speed footage of the projectile impact and examination of the recovered projectile, offering unique insights into historical ballistics.

This entry analyzes firearm mishaps presented in a 'Darwin Awards' style, emphasizing critical safety lessons. Instructor Brandon Herrera, a recognized firearm manufacturer and commentator, uses real-world examples to illustrate the severe consequences of ignoring basic gun safety rules. The content serves as a cautionary guide, highlighting common errors in handling, trigger control, and the dangers of seeking online notoriety through unsafe practices.

Brandon Herrera, a recognized firearms expert and manufacturer, uses high-speed footage and ballistic testing to analyze the assassination attempt on Donald Trump. The video aims to debunk conspiracy theories by demonstrating the ballistics of a 5.56mm round grazing an ear and the effectiveness of counter-sniper fire from a .300 Win Mag rifle. Herrera emphasizes the difficulty of precise shots at range and condemns political violence.
