Tiny Tool!

This video focuses on the intricate machining process of trunnions for the BFG-50A rifle. The creator highlights the challenges encountered, particularly with creating small threaded holes for a patented spoke system, and expresses relief at overcoming these hurdles. The content is aimed at those interested in the technical aspects of firearm manufacturing and CNC machining, promising to share interesting insights for viewers not already familiar with the field.

This video showcases the machining process for the receiver of a BFG-50A rifle. The creator highlights that the receivers are nearing completion, with only a few more steps before they are sent off for nitriding. The description also includes a thank you to viewers who offered suggestions regarding the coolant used on the machining equipment, indicating an interactive and community-engaged approach to the content.

This video showcases the impressive speed and effectiveness of a super-expensive tungsten carbide, through-coolant drill bit being used to create firing pin holes in BFG-50 bolt heads. The description highlights the difficulty of drilling high-strength alloy steel and uses a humorous analogy of being accused of witchcraft if this technology were shown centuries ago. The drill's performance is presented as almost unbelievable due to its speed and capability on tough materials.

This YouTube video features a discussion about the BFG-50A bolt carrier. The creator acknowledges a two-month gap since their last video and mentions they are working on a more involved project. In the interim, they plan to talk for over 10 minutes, dedicating a portion of that time specifically to the BFG-50A bolt carrier. The video seems to be an impromptu update and discussion rather than a formal review or demonstration.

This YouTube video explores an "oddity" in the gas system of the BFG-50A rifle. The creator initially found the high-speed video of the gas piston's motion perplexing, recalling that they had experimented with the system extensively in 2018 without fully understanding its peculiar behavior. The creator hints that the explanation came to them after filming, and the video aims to see how many viewers can deduce the reason behind the gas system's unusual movement.

This video showcases a new, patent-pending handguard attachment method for the BFG-50A rifle. The creator details their discovery of this innovative technique and shares it with viewers, humorously noting their current demonetized status. The focus is on the practical application of gunsmithing and firearm modification.

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.
