RN-12 Shotgun Pistol Review

This review covers a custom-built, ultra-compact 12-gauge shotgun pistol, highlighting its garage-built origins and simple design. Testing reveals significant power and recoil, necessitating mini shells and manual extraction. While potent, its extreme inaccuracy and painful shooting experience render it a novelty rather than a practical firearm.

The Techno Arms MAG-7 is a rare South African 12-gauge shotgun pistol notable for its magazine-fed, pistol-grip design. However, its practicality is severely hampered by its exclusive requirement for expensive and hard-to-find 2-inch shells, with standard or mini-shells causing significant feeding issues. While visually unique, its performance in testing was plagued by jams, making it more of a collector's item than a reliable firearm.

The RN-45 is a custom-built firearm by Royal Nonesuch, featuring a unique blend of parts including a Sten Mark III receiver, M3 Grease Gun bolt, and AK-style stock. High-speed footage reveals feeding issues and occasional misfires due to cartridge bounce in the chamber. The build's rate of fire is confirmed at 465 RPM.

The Taurus Judge Public Defender is critically assessed as a novelty item rather than a reliable self-defense handgun. While capable of firing .410 shotshells and .45 LC, testing revealed significant reliability issues, including cylinder seizure with certain .410 loads. Accuracy with buckshot and slugs was poor, and individual .410 pellets lacked the penetration of a 9mm round, making it unsuitable for primary self-defense.

This YouTube video provides an overview of the LeMat Revolver. While the description is currently unavailable, the title indicates a focus on this historical firearm. The content is expected to delve into the features, design, and possibly the history or usage of the LeMat, making it relevant for firearms enthusiasts interested in unique or antique revolvers.

This video features a review of the RN-50 firearm with guest Royal Nonesuch. The discussion delves into the history of the RN-50 and uncovers some of its lesser-known aspects. The collaboration suggests a focus on firearm history and potentially practical insights.

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.
