Barrel Corrosion & Fix

This video details the comprehensive restoration of a heavily rusted 1977 Winchester 94 rifle damaged in a 2016 cabin fire. The process, expertly demonstrated by D'Boss Firearms, involves meticulous disassembly, chemical rust removal using Evapo-Rust, stock and sling refurbishment, cold bluing with Stock Doc Nu-Blu, and careful reassembly. The restored rifle is then successfully test-fired, showcasing a complete functional and aesthetic revival.

This guide details an expert-level approach to cleaning a neglected black powder revolver, contrasting ultrasonic cleaning with a dishwasher experiment. The instructor, with 20 years of experience with black powder firearms, demonstrates the effectiveness of an ultrasonic cleaner using Dawn dish soap and Ballistol, recommending it over the dishwasher method which caused rust and removed bluing. The process includes disassembly, ultrasonic cleaning, lubrication, and bore scope inspection.

This video demonstrates how to remove light rust from firearms using common household and gun cleaning products. It differentiates between light surface rust, which can be wiped away with oil or solvent, and heavier orange rust, which requires 0000 grade steel wool soaked in oil or solvent. The importance of proper storage and preventative maintenance to avoid rust is also emphasized.

This video demonstrates a practical method for removing rust from surplus AK-47 magazines using common household cola. It provides a step-by-step guide on how to clean and restore these essential firearm components, ensuring their continued functionality and preserving their condition. The video also includes links to the creator's social media platforms for further engagement.

This YouTube video title, translated from Thai, indicates a focus on two .308 caliber firearms being cleaned to remove rust. The content likely involves a gunsmithing or maintenance process, detailing the steps taken to restore the firearms.

This expert guide details a comprehensive 'barrel autopsy' procedure, as demonstrated by the School of the American Rifle. It covers essential checks including thread concentricity, material identification, magnetic properties of the extension, erosion gauging, bore straightness, gas port alignment, and headspace verification using specialized gauges. A critical borescope inspection revealed a manufacturing defect: a smoothbore barrel lacking rifling, highlighting the importance of thorough inspection regardless of brand or price due to potential quality control lapses.

This video details the diagnosis and repair of a feeding issue on a Sons of Liberty Gun Works East India upper receiver. The root cause was identified as a sharp burr on the barrel extension's feed ramp, causing rounds to jam. The solution involved polishing the feed ramps and adding a secondary bevel, replicating Colt's design, which successfully resolved the malfunction.

This video demonstrates the internal mechanics of an AR-15 bolt carrier group using cutaway models. It highlights the importance of internal bore dimensions for gas system efficiency and explains how to diagnose potential issues like gas leaks. The demonstration covers the cycle of operation, critical seals, and common manufacturing defects, offering advanced insights for AR-15 maintenance and troubleshooting.

This video provides a detailed autopsy of a faulty AR-15 Bolt Carrier Group (BCG). The analysis reveals critical manufacturing defects including an undersized bolt tail failing gauges, excessive firing pin protrusion causing pierced primers, an oversized firing pin hole, and an oversized cam pin hole leading to headspace issues. These flaws significantly compromise the BCG's function and reliability.

This video demonstrates a specialized technique for swapping an AR-15 rear takedown pin without full firearm disassembly. It highlights the use of a custom-fabricated tool, often made from a 1/16 inch Allen wrench, to depress the detent. The method allows for efficient pin replacement, particularly useful on rifles with staked castle nuts, by leveraging the old pin to guide the new one into place.
