This guide details the meticulous gunsmithing process for restoring a Japanese contract Peabody rifle, as demonstrated by expert Mark Novak. It covers identifying and repairing damage, fabricating replacement parts like the rear sight spring and screws, performing essential heat treatment, and reassembling the action. The process emphasizes conservation techniques over destructive restoration, culminating in successful range testing.

This guide details the process of finishing a replacement rifle bolt handle, as demonstrated by Larry Potterfield of MidwayUSA. It covers heating and bending the handle, shaping it with files, and crucially, grinding a necessary recess into the rifle receiver for proper function. This is an intermediate-level gunsmithing task requiring specialized tools and careful execution.

Larry Potterfield, founder of MidwayUSA, demonstrates a practical gunsmithing technique for fabricating a new firing pin from drill rod. This guide covers essential machining steps on a lathe, including turning diameters and marking with layout dye, followed by shaping, finishing, and crucial heat treatment via torch and oil quench to ensure durability. The process highlights how common issues like a broken firing pin can be resolved with basic tools and methodical execution.

This video delves into the core attributes that define an ultimate rifle, focusing on barrel manufacturing, trigger design, and overall firearm design simplicity. It highlights the importance of precise barrel making, including the benefits of 5R rifling for reduced fouling and the critical role of concentricity. The discussion extends to trigger feel and consistency over mere weight, and the advantages of simpler, modular designs like the Thompson/Center Icon for accuracy and reliability. The content emphasizes Thompson/Center's innovative approach to firearm design, prioritizing performance and repeatability.

This video details a comprehensive custom build on a Kimber Eclipse Custom 2 1911 by MK3 Firearms. Key modifications include a full heat treatment of the stainless steel, installation of an Ed Brown Match Fit threaded barrel, Crimson Trace laser grips, a Fusion Firearms mainspring housing with lanyard loop, and a Wilson Combat safety. The build also features a custom single-stage trigger job for enhanced performance and reliability. The speaker's professional gunsmithing expertise is evident throughout the detailed explanation of each upgrade.

Mark Serbu demonstrates the flame hardening process for the ejection port edge of a BFGA receiver. This technique uses an oxy-acetylene torch to heat the steel to its austenitization temperature, followed by rapid quenching in water. The purpose is to harden the edge, preventing it from bending or dinging when large caliber casings are ejected, thereby increasing the receiver's durability.

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.
