Sporterizing the Mosin Nagant Part 3- Cosmoline Removal

This guide details the process of 'sporterizing' a Swiss K31 rifle to improve its accuracy and modern usability. It covers essential gunsmithing techniques such as stock refinishing and advanced glass bedding to ensure a stable action-to-stock fit. The modifications are designed to be non-permanent, preserving the rifle's historical value while enhancing its performance with modern optics.

This guide details the process of removing stubborn Cosmoline from surplus firearms, specifically Chinese Type 56 SKS carbines. It covers field stripping, using heat to 'sweat' Cosmoline from wood, sonic cleaning small parts, and employing non-chlorinated brake cleaner for metal components. Safety precautions, such as ensuring the firing pin channel is clear to prevent slam fires, are emphasized.

This video provides a comprehensive guide to fixing a sticky Mosin-Nagant bolt, a common issue often caused by dried cosmoline. It details methods for polishing the chamber and firing pin, lightening the firing pin spring, and smoothing critical contact points. The tutorial also covers extractor adjustment and recommends specific lubricants like Ballistol and Loctite C5-A for improved operation and accuracy through tang bedding.

This video details the precise process of drilling and tapping a Mosin Nagant receiver for a Rock Solid scope mount using a Forster Products jig. Key steps include using a #21 drill bit with cutting oil, tapping with a 10-32 tapered tap, and carefully measuring depth to avoid the chamber. The process emphasizes accuracy and chip management for a secure mount.

This video details critical safety checks for sporterizing a Mosin Nagant M91/30, focusing on headspace and firing pin protrusion. It demonstrates bolt disassembly, extractor removal, and the use of headspace gauges. The rifle passes these essential safety tests, clearing it for further modification and shooting.

This video provides a comprehensive guide to removing cosmoline from a surplus SKS rifle, essential for safe and reliable operation. It details the field stripping process, effective cleaning methods using mineral spirits and tools like RamRodz, and emphasizes critical areas such as the bolt and gas system to prevent slam fires. Proper reassembly and lubrication are also covered, concluding with successful range testing.

This video hilariously tests a heavily accessorized AR-15, dubbed the 'Zombie Carbine,' as a parody of excessive tactical gear. The build, based on a Smith & Wesson M&P15, weighs 23 pounds fully loaded with 270 rounds across nine magazines. It features multiple optics, lasers, lights, and is demonstrated with rapid fire, hip sniping, and Tannerite explosions.

This "ultimate AR-15 meltdown" test pushes a custom build to its limits, revealing key durability insights. The Faxon barrel ultimately burst after 830 rounds, but critical components like the Sharps SRC bolt carrier group and Geissele rail demonstrated impressive resilience under extreme stress and heat. The test highlights the AR-15 platform's robust design, even when subjected to conditions far exceeding typical operational use.

This video showcases an extreme full-auto durability test of a premium Definitive Arms VEPR AK, comparing it to a budget WASR-10. The VEPR AK demonstrated exceptional resilience, enduring 895 rounds before failure, significantly outperforming the WASR-10 and even a previously tested AR-15. The expert analysis highlights the AK platform's inherent durability and heat management characteristics, even under severe stress.

This video demonstrates the legendary durability of the AK platform by subjecting a Yugo M92 PAP to a 700-round continuous firing test. Despite extreme heat causing significant smoke and glowing metal, the firearm remained functional, showcasing Mikhail Kalashnikov's robust engineering. The test concludes with a cooling process and a tribute to the designer's legacy.
