Cold Bluing Revisited: Brownell's Oxpho Blue Part 3

Roy Huntington, a recognized expert in the firearms industry, provides an instructional update on cold bluing a custom Smith & Wesson J-frame revolver. He details the critical metal preparation steps, emphasizing a 500-grit finish, and demonstrates the application of Brownells Oxpho-Blue Creme Formula. The guide highlights how meticulous prep work can achieve a professional-looking hot blue finish using a cold bluing method, impressing even seasoned firearms enthusiasts.

This guide details a DIY method for cold bluing firearms, emphasizing proper surface preparation and application techniques. Key steps include degreasing, warming the metal, applying multiple coats of bluing solution, and blending with 4-0 steel wool. The process aims to achieve a presentable finish for touch-ups or full refinishing on less valuable firearms.

This guide details a cold bluing touch-up technique using Brownell's Oxpho-Blue, as demonstrated by Iraqveteran8888. The process emphasizes meticulous metal preparation, careful application of the bluing solution, and controlled buffing to achieve a durable and aesthetically pleasing finish. The speaker's experienced approach highlights nuances in metal prep and chemical interaction for optimal results.

The speaker, Justin Evans, discusses rust bluing versus cold bluing finishes. While not a fan of either, he expresses a preference for rust bluing over cold bluing, noting that cold bluing often looks poor. He suggests that other finishes, like case hardening, would be preferable to both.

The video details the process of modifying a rail for a Colt Python revolver to fit a 4-inch barrel. The presenter explains how the original rail was designed for a 6-inch barrel, requiring it to be shortened and refinished in black ceramic coating. The process involved cutting the rail, applying a finish to the bare metal, and adjusting it to match the gun's body length. The presenter also discusses potential future modifications to fill a small recess at the front of the rail.

This video showcases two AKM rifles built by Childers Guns using clone-correct receivers. The builds highlight the attention to detail, including serialized receivers matching original kits and the application of Russian Paint.net's finish, which replicates the original military paint's chemical compound, durability, and appearance. The video also touches on the variations found in different AK kits, particularly from Izhevsk and Tula, and the aesthetic differences in wood furniture.

This video provides an expert-level overview of a heavily customized AR-15, nicknamed the 'Zombie Destroyer', built for a thematic zombie apocalypse scenario. The build features an extensive accessory loadout including multiple optics, lasers, and flashlights, along with a high magazine capacity. The demonstration includes rapid fire, engagement of Tannerite targets, and unique shooting techniques, showcasing the rifle's capabilities and the instructor's proficiency.

This video details an extreme AR-15 meltdown test, pushing a custom build to its limits. Expert instructor Eric demonstrates the process, highlighting component durability and failure points under sustained fire. The test concludes with a catastrophic barrel failure after 830 rounds, providing valuable insights into the platform's resilience.

This guide details the process of conducting an extreme durability test on an AK-47 variant, specifically the Definitive Arms VEPR, as demonstrated by Iraqveteran8888. The test involves sustained full-auto fire to induce critical heat failure, followed by inspection of components like the barrel and gas block. The expert assessment highlights the rifle's resilience, lasting 895 rounds before failure, and compares its performance to other platforms.

This guide details a 700-round rapid-fire stress test on a Yugo M92 PAP AK-47 variant, demonstrating the platform's legendary durability under extreme heat. Performed by Eric from Iraqveteran8888, the test highlights safe handling of overheated firearms and concludes with a tribute to Mikhail Kalashnikov's engineering legacy. The firearm successfully completed the test despite significant heat buildup.
