RN-50 vs C4 AFTERMATH!

This video concludes the RN-50 blow-up analysis, identifying the primary cause as the use of fast-burning pistol powder instead of slow-burning .50 BMG powder. Mark Serbu demonstrates how this error can create pressures exceeding 400,000 PSI, far beyond the rifle's design limits. The analysis includes comparisons with standard .50 BMG loads and even high explosives, using simulations and analogies to explain the catastrophic failure.

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.

This video compares the destructive power of a custom Micro 50 BMG rifle against ballistic gel and a realistic human torso dummy. It also features a comparison with an 18-inch RN-50 and a .44 Magnum Desert Eagle, highlighting differences in impact effects. The content culminates with a demonstration of a custom 7-round shotgun firing Dragon's Breath, buckshot, and slugs simultaneously, completely obliterating the torso.

This review showcases the unique Serbu Micro .50 BMG, a custom firearm with a 10-inch barrel based on the RN-50 receiver. Despite its compact size, initial firing tests revealed manageable recoil. The video includes penetration tests comparing different barrel lengths and destructive capability tests using API rounds against oxygen tanks, highlighting the .50 BMG's power.

This review showcases the Serbu .50 BMG Micro, a compact anti-materiel rifle with a 10-inch barrel, provided by designer Mark Serbu. The video highlights its compact handling, the ability to attach stocks, and the use of budget red dot sights. It's presented as a unique, large-caliber firearm suitable for specific applications.

This video compares the "RN 50" and "C4" in a somewhat unscientific manner, reminiscent of Edwin Sarkissian's style. The creator discusses observed phenomena, particularly refuting the idea that a .50 BMG round could be responsible for a specific accident due to the distinct damage patterns compared to high explosives. The video offers a quick look at interesting aspects and promises a follow-up installment.

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.

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.
