RN-50 Review with Royal Nonesuch

This review of a 9mm AR-15 by Mark Serbu, a recognized gun designer, delves into its functionality, historical context, and potential issues. Serbu highlights the use of Glock magazines with a magwell adapter, discusses trigger pack design, and analyzes bolt velocity and its impact on trigger slap, especially in converted full-auto variants. He also details the effectiveness of heavy buffers and stronger springs in managing rate of fire and recoil, comparing it to Uzi and MP5 submachine guns.

This interview with Mark Serbu addresses the safety of the RN-50 firearm, particularly in light of an incident involving Scott from Kentucky Ballistics. The consensus points to a misloaded cartridge, likely using pistol powder in a 50 BMG case, leading to extreme over-pressurization (estimated at 190,000 PSI). Serbu explains that 50 BMG's normal pressure is around 55,000 PSI and discusses the difference in energy release between various propellants and explosives, emphasizing that impact loading from rapid-burn powders can be destructive.

This video showcases the unique Serbu 50 BMG Micro rifles, featuring 10-inch barrels and a break-action design. The creator demonstrates firing two simultaneously, highlighting the extreme recoil and shockwave generated by the .50 BMG caliber. The review emphasizes the custom build aspect and the intense physical experience of handling these powerful, compact firearms.

This video showcases the RN50, a .50 BMG rifle designed by Royal Nonesuch. The rifle features an 18-inch barrel, a folding stock, and a brake action with a breach cap for reloading. It's described as a lot of fun to shoot, with a significant recoil that 'blows your hair back'. The design prioritizes simplicity and affordability.

This video provides an in-depth look at the Czechoslovakian VZ-61 Scorpion submachine gun, focusing on its unique features and historical context. Mark Serbu, a gun designer, shares his excitement about acquiring and demonstrating the firearm, highlighting its 32 ACP caliber, 20-round magazine capacity, and the function of its rate reducer. The video also touches on the availability and cost of parts kits, the craftsmanship involved in its production, and comparisons to other firearms.

Mark Serbu provides an early look at the Avangard AR upper, formerly the SC15, highlighting its lightweight design, hidden gas block, and quick-change barrel feature. He also briefly showcases a 2011-style handgun from Houston Miller's company, Miller Precision Firearms, praising its smooth operation and trigger.

This guide details the complex process of converting a lathe into a 12-barrel blank-firing gun, as demonstrated by Mark Serbu. It highlights the critical engineering challenges, including precise alignment, CNC control, and the application of PID theory to overcome firing inconsistencies. The project emphasizes safety and legal considerations, focusing on blank ammunition to avoid machine gun manufacturing regulations.

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 expert-level analysis of a catastrophic failure of the Serbu RN-50 rifle, presented by the firearm's designer, Mark Serbu. The examination focuses on the severe damage to the receiver, breech cap, and barrel assembly, offering insights into potential failure points and the effects of extreme forces. The analysis also touches upon the ammunition used, specifically SLAP rounds, and their potential role in the incident.

Mark Serbu, a gun designer, addresses the RN-50 blow-up incident involving Scott from Kentucky Ballistics. Serbu reassures customers that the RN-50 is a safe design, attributing the incident to a counterfeit and faulty ammunition round. He emphasizes the importance of sourcing ammunition carefully and highlights the rifle's extensive safe operational history.
