Bayonet won't Fit your Mosin? Here's the best way to get a perfect fit...

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 video details the comprehensive gunsmithing process for a custom 'truck gun' build based on a 1917 Enfield rifle. Expert gunsmith Mark Novak explains the restoration of a damaged rifle, including stock re-contouring and applying a specific finish. Key modifications involve threading the barrel for a modified M14 flash hider, making it suppressor-ready while preserving the original sight radius. The project culminates in a live-fire demonstration highlighting the rifle's reliability and smooth operation.

This guide details the straightforward installation of the MDT Oryx chassis system onto a Remington 700 pattern rifle, such as the Taurus Expedition. The process requires only two screws for securing the action, highlighting the simplicity of this rifle upgrade. The MDT Oryx chassis offers significant improvements including AR-15 grip compatibility, an adjustable cheek riser, and ample rail space.

This guide details the installation and testing of a Strange Waters conversion kit for an AR-22 platform, enhanced with Bore Buddy springs and a Whisper Strike suppressor. The video demonstrates how these upgrades resolve previous reliability issues, allowing the rifle to function smoothly. It emphasizes the importance of specific components for optimal performance and includes live-fire testing to confirm functionality.

This analysis from Forgotten Weapons details how political corruption nearly led to a flawed Mosin-Nagant rifle variant being adopted. The modified rifles, including those with barrel fluting, did not outperform standard M91s in accuracy and exhibited reliability issues. The significant cost of retrofitting these changes was not justified by performance gains, yet 32,000 units were ordered due to political connections, highlighting a case where politics superseded sound engineering and testing.

This guide details how to build a budget-friendly Ruger 10/22 target rifle, leveraging aftermarket parts for improved accuracy and ergonomics. The process involves modifying the receiver for a more secure optic mount, selecting a rigid stock, and installing a quality barrel and scope. The speaker, an experienced DIY builder, emphasizes practical solutions for common issues like stripped receiver threads.

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.
