I shot a fan!

This video details the multi-week restoration and reassembly of a 3-inch M5 anti-tank gun. The process involves extensive cleaning, blasting, bodywork, welding, priming, and painting of various carriage components, including the axle, legs, hubs, brakes, and shield. The final stages focus on bottom-up reassembly, installation of functional parts like the traverse mechanism, and the mounting of the gun and its dummy breach. The project is nearing completion for museum display.

This guide details the assembly and basic operation of the Bear Creek Arsenal BC15 bolt-action AR upper, as presented by Moondog. It covers mounting the upper, cycling the action, and bolt removal for cleaning. The review highlights the budget nature of the component, noting potential cosmetic blemishes and a rough action requiring break-in and lubrication.

This video details the repair process for a broken lug on a Mark Serbu RN-50 rifle. Lead Firearms Instructor and SEO Strategist Mark Serbu walks through the steps of removing the barrel, welding the lug back on, and refinishing the receiver with parkerizing. The repair is demonstrated to be successful through test firing, highlighting the importance of proper gunsmithing techniques for firearm longevity and safety.

Mark Serbu demonstrates the process of designing and fabricating sheet metal dies to stamp firearm components, inspired by the WWII-era Sturmgever. He details the challenges of die creation, including machining and heat treatment, and showcases the successful stamping of a component using a 200-ton hydraulic press. The video highlights the potential for efficient manufacturing through stamping compared to traditional CNC machining of aluminum.

This guide details the manganese phosphating (Parkerizing) process for firearm refinishing, as demonstrated by an expert gunsmith. It covers essential steps from initial disassembly and ultrasonic cleaning to sandblasting, the chemical etching process, and final oil saturation for corrosion resistance. The expert emphasizes meticulous metal preparation and the use of custom fixtures for an even, durable finish.

Mark Serbu demonstrates an unconventional but effective method for removing a stubborn lug from an RN50 firearm. By utilizing impact loading with a firearm and 7.62x39mm ammunition, he successfully dislodged the part after conventional methods failed. This technique highlights the principle that forceful impact is a powerful way to break free seized components, a concept applicable in engineering and gunsmithing.

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.
