Mosin Nagant Bolt Assembly Disassembly M39 M38 M44 91/30 M91 1891 Dragoon 7.62x54r .311 .310 .313

This video details a project to enhance a Mosin Nagant 91/30 rifle for a more enjoyable shooting experience. The creator discusses previous unsuccessful attempts with cheap parts and focuses on using a precision machined rail, a proper eye relief scope, and a Howling Raven muzzle brake. The goal is to improve practical accuracy beyond 100 yards, addressing factory sights' inaccuracies and a loose front sight. The rifle is a 1935 Izhevsk hex receiver model with matching numbers, noted for its condition despite blemishes. The creator also mentions owning an M44 and aspiring to own an M53.

This video showcases a 7.62x54R Mosin action being tested on a stand. The description emphasizes that the content is for educational purposes and not a tutorial, warning viewers against attempting such procedures without the necessary skills. It features a strong disclaimer about safety and skill requirements. The title also humorously references a common Soviet sentiment: "Nyet! Weapon is fine!". The music used is titled "7.62x54r Sound of Soviets".

This video, part 4 of 4 in a series from Brownells, provides a step-by-step guide on how to properly reassemble a Mosin Nagant rifle. The content focuses on the practical aspects of firearm maintenance and is presented by one of their gunsmiths. The description also points viewers to subsequent videos covering disassembly, cleaning, and lubrication of the same firearm, and directs them to the Brownells website for related products and more how-to guides.

This video demonstrates the effectiveness of polishing the bolt and chamber on Mosin Nagant rifles to resolve the common 'sticky bolt' issue. Guest Mr. Hill tests an M44, M28, and M39, noting significant improvements in bolt cycling smoothness and overall operation. The M39 is highlighted as a high-quality variant, with the host also demonstrating its reliable performance.

This guide details the field stripping process for a Japanese Type 30 infantry rifle, as demonstrated by C&Rsenal. The procedure involves removing the bolt, disassembling the bolt head and rear components, and extracting the firing pin and sear. The instructor emphasizes using appropriate tools for compressing the firing pin spring to avoid damage. The video questions the practicality of this level of disassembly for field cleaning.

This video details the essential components of an AK bolt repair kit, including the firing pin, extractor claw, and retainer pins, highlighting their importance for maintaining AK47 reliability. It demonstrates proper disassembly and reassembly of the bolt and recoil spring assembly, emphasizing common failure points like cracked extractor claws and damaged firing pins due to improper maintenance. The content stresses the value of carrying these small, critical parts for field repairs.

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.
