GB-22 Plan Update REDO

This video captures a humorous and somewhat tense moment when Royal Nonesuch is pulled over by law enforcement. The description highlights the friends' reaction to the situation and suggests the driver may have been profiled for his vehicle. While the interaction with the police was resolved amicably without a ticket, the experience prompts a reflection on profiling and encourages viewers to share their own cop stories. The creator also directs viewers to their secondary gun channel.

Mark Serbu provides a preliminary analysis of the RN-50 incident, debunking the 85,000 PSI failure rumor by calculating thread shear pressure at 161,520 PSI. He confirms production RN-50 breech caps are heat-treated, unlike an old prototype. The analysis suggests the failure was likely due to counterfeit SLAP ammunition, possibly loaded with incorrect powder, rather than a design flaw.

This video tests a custom .50 BMG arrow designed to fire its round upon impact. Initial tests with a recurve bow failed due to the round falling out, but a successful ignition was achieved after securing it with tape, causing a significant explosion on a car door. Further tests showed dangerous ricochets and poor accuracy due to the arrow's extreme weight distribution, making it unsuitable for precise targeting.

This video explores the plausibility of Fallout 4's pipe guns by comparing them to real-world improvised firearms. A functional 12-gauge slam-fire shotgun was constructed for $20 and tested, proving lethal at close range. Technical inconsistencies in the game's caliber choices for revolvers and semi-autos are highlighted, contrasting with the effectiveness of simple, improvised designs in survival scenarios.

Mark Serbu details the complex process of converting a CNC lathe into a 12-barrel blank-firing machine gun. The project highlights the critical role of a lathe's C Axis for precise rotational control and the application of PID control theory to overcome initial firing failures. Modifications were made to ensure the device fires blanks only, avoiding legal issues.

This video demonstrates how to rifle a barrel in a home shop using basic tools, bypassing expensive CNC equipment. It covers material preparation, precise drilling and reaming, and the critical process of pushing a rifling button. While a DIY approach is shown to be possible, the video highlights the significant difference in quality and precision achievable with professional CNC machining.

This video provides an in-depth analysis of the Serbu RN-50 rifle that experienced a catastrophic failure during a Kentucky Ballistics test. Mark Serbu, the designer, meticulously examines the damage, noting severely bent steel side plates, sheared-off breech cap ears, and a sheared pivot pin. The inspection also covers the breech cap's condition, barrel threads, and the stuck casing, revealing a case head separation.

Mark Serbu, designer of the RN-50, addresses a catastrophic failure experienced by Kentucky Ballistics. He reassures customers about the RN-50's safety, attributing the incident to counterfeit or over-pressured ammunition. Serbu highlights the rarity of such events and emphasizes industry transparency, noting that his company has produced approximately 1,400 RN-50s since 2016 with hundreds of thousands of rounds fired without issue.
