How the ROF ejector works

This video features Master Gunsmith Jack Rowe discussing the different styles and components of side locks found in English shotguns. This is the first part of a two-part series. The content is aimed at providing detailed knowledge about shotgun lock mechanisms and is a valuable resource for those interested in gunsmithing or the technical aspects of firearms.

This video focuses on improving firearm ejection reliability using a Radian Ramjet and Afterburner combination. The creator experiments with different recoil springs (15lb and 13lb) in an attempt to achieve smoother and more consistent ejection patterns. The description also highlights the potential applications of this setup for home defense, as a truck gun, or for everyday carry (EDC), with mentions of WROL (Without Law Enforcement Response) and TEOTWAWKI (The End Of The World As We Know It) scenarios, indicating a focus on survival and preparedness.

This guide details the unique ejection and reloading process for the Colt 1860 Army Thuer Conversion, a rare front-loading cartridge revolver. Experts from Brownells demonstrate how to use the selector lever for ejection and how the firearm itself, with a specialized tool, serves as the reloading apparatus. The video highlights the historical context of this conversion, designed to circumvent patent restrictions.

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.
