This video demonstrates the industrial process of rifling a Savage Rifle Barrel using a button rifling technique. A factory worker applies lubricant to a rifling rod before pulling it through the barrel blank under high tension, cold-forming the lands and grooves. The process highlights precision handling and standardized industrial safety protocols, showcasing the manufacturing of firearm components.

This video provides an in-depth look at modern firearm barrel manufacturing processes, focusing on the differences between Nitride (QPQ) and Chrome lining. Nathan from Faxon Firearms explains the metallurgical science behind these treatments, their impact on accuracy, corrosion resistance, and heat management. The discussion also covers various rifling methods and the critical importance of stress relief for thin-profile barrels.

This guide details a rigorous inspection and testing procedure for AR-15 barrels, as demonstrated by Preston Moore. It covers essential physical gauging, advanced borescope analysis to detect internal defects like pitting, and a structured approach to range testing with various ammunition types. The process emphasizes data collection for accuracy and velocity, highlighting the importance of thorough evaluation before and after live fire. Moore's objective and analytical approach provides high-level insights into barrel quality.

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.
