This YouTube video offers practical tips and techniques for polishing stainless steel firearm components. The content focuses on achieving a high-quality finish on gun parts, likely aimed at gunsmiths, hobbyists, and firearm enthusiasts looking to customize or maintain their weapons. The video emphasizes real-world application and likely demonstrates various methods and tools used in the polishing process for stainless steel firearms.

This expert-level guide details the step-by-step disassembly of the Ruger 10/22 rifle, as demonstrated by Ruger Firearms. It emphasizes crucial safety precautions, including confirming the firearm is unloaded and wearing safety glasses. The process requires minimal tools: a 5/32 Allen key and a small punch, making it accessible for routine maintenance and cleaning.

This guide, presented by School of the American Rifle, details how to identify and replace a malformed weld spring in an AR-15 Delta Ring assembly. A misaligned weld spring can cause the gas tube to be pushed off-center, leading to excessive friction or damage to the carrier key and gas tube. Replacing the faulty component ensures proper gas tube alignment and firearm reliability.

This video demonstrates John Lovell's preferred method for lubricating an AR-15, prioritizing oiling over extensive cleaning for standard maintenance. Key steps include applying Slip 2000 EWL directly to the Bolt Carrier Group (BCG) through the ejection port and magazine well, ensuring lubrication of vent holes and internal components. The process also covers lubricating the receiver and star chamber, followed by cycling the charging handle to distribute the lubricant effectively.

This video provides a tutorial on how to field strip the AK-47 platform. The title suggests a practical, hands-on demonstration of disassembling the firearm for cleaning and maintenance.

This video, titled 'Bore Buddy - Not Full Auto FRT', appears to be a discussion or demonstration related to firearm components, specifically the 'Bore Buddy' and its connection or lack thereof to 'Full Auto FRT' (likely referring to a Full Auto sear or trigger mechanism). Given the title's focus on a specific component and its function, the content is likely technical in nature, potentially exploring modifications, functionality, or limitations of this firearm part. The absence of a transcript requires an assumption that the video delves into the operational aspects of the Bore Buddy.

This video tests how many cast iron skillets are needed to stop various bullets, from .22 LR to 500 S&W Magnum. Most common handgun rounds like 9mm and .45 ACP are stopped by two skillets. Rifle rounds like 5.56mm and 7.62x39mm also require two to three skillets, while the powerful 500 S&W Magnum penetrates three and is stopped by the fourth. The .22 LR failed to penetrate even the first skillet.

This video tests the penetration capabilities of a .50 BMG rifle, specifically the Serbu BFG-50A, against a section of railroad track. Various .50 caliber rounds, including Raufoss Mk 211 API and silver tip API, were fired. While the rifle and ammunition demonstrated the ability to penetrate even the thickest parts of the rail (over 1.5 inches), bullet deflection and shifting upon impact with the dense steel were observed.

This video demonstrates launching an M67 fragmentation grenade using an X Products Can Cannon towards a distant frozen lake. The Can Cannon, firing .223 blanks, successfully propels the grenade, which detonates upon impact, creating a visible hole in the ice. The experiment highlights the launcher's capability for extreme projectile delivery in challenging outdoor conditions.

This video tests the destructive power of a .50 caliber spotter round against 1.25-inch thick bulletproof glass, comparing it to a standard FMJ round. The spotter round, designed to spark and flash, created a larger crater and more surface damage than the FMJ round, demonstrating its specialized impact characteristics. The Serbu BFG-50A rifle was used for both tests.
