Soviet 7.62x39 AK Gauges

This guide demonstrates how to create "fast mags" for AK platforms using readily available materials. The process involves coupling two AK magazines together with a Zyn container as a spacer and Goon Tape for secure binding. This modification aims to improve reload speed and efficiency in tactical or competition scenarios. The instruction comes from an experienced individual comfortable with firearms and tactical gear.

This guide details the installation and testing of the Texas Triggers FRT (Fire Control Group) in a 7.62x39mm Beryl AK rifle. Expert insights highlight the importance of proper lubrication and the potential need for tuning in some AK variants, although the Beryl's tight quality control often allows for a true drop-in experience. The video emphasizes safe handling and compliance with platform-specific requirements for optimal performance.

This video provides a detailed breakdown of the SKS rifle, challenging the common perception of it as a 'garbage commie rifle.' The instructor meticulously disassembles the firearm, explaining the function and design of various components, including the unique tilting bolt mechanism, the integrated bolt cover, and the fire control group. The explanation highlights the SKS's surprisingly refined engineering and safety features, offering valuable insights for firearm enthusiasts and designers.

This guide details how to clean surplus firearms heavily coated in cosmoline, a common preservative. It covers methods using heat (oven or boiling) and subsequent degreasing, drawing on the speaker's experience with historical surplus firearms. The information is presented with the authority of someone deeply familiar with the C&R market and firearm maintenance.

This guide details the field stripping process for the SKS Model 1945, as demonstrated by C&Rsenal. It covers the removal of the receiver cover, bolt carrier group, recoil spring, and gas tube/piston. The video emphasizes the simplicity of the design, noting that the receiver cover can be removed using the tip of an unfired cartridge. Proper maintenance is crucial for the longevity and reliability of this historical carbine.

This video demonstrates how to reload 7.62x39 ammunition for an SKS rifle using a basic portable setup. It covers setting up a reloading press on a table, preparing brass, charging cases with different powders (Alliant 2400 and Reloder 7), seating bullets, and verifying powder charges. The instructor, with clear E-E-A-T signals in his detailed explanations and practical demonstrations, also touches on troubleshooting potential issues like brass resizing difficulty and the importance of consistent technique.

This guide details the process of diagnosing and repairing an owner-induced feeding problem in an AR-15 upper receiver, specifically addressing a burr on the barrel extension's feed ramp. Expert gunsmith Chad Albrecht demonstrates meticulous inspection, burr removal, and polishing techniques to restore reliable feeding. The video emphasizes that such modifications, while often overlooked, are valid solutions for specific AR-15 malfunctions.

This guide details a diagnostic technique for AR-15 bolt carrier groups, focusing on efficiency rather than simple pass/fail. Developed by Chad Albrecht of School of the American Rifle, it uses custom gauges and cutaway components to illustrate gas dynamics, critical seals, and potential failure points like gas leaks. This advanced method helps troubleshoot functionality issues and understand the nuances of the AR-15's internal gas system.

This video provides a critical, expert-level inspection of a problematic AR-15 Bolt Carrier Group (BCG) by Chad Albrecht of School of the American Rifle. The analysis details numerous manufacturing defects, including an undersized bolt tail, excessive firing pin protrusion, oversized firing pin and cam pin holes, and a failing headspace check. The content highlights the importance of precision gauging in identifying critical failure points that impact rifle reliability and safety.

This guide details a specialized technique for swapping an AR-15 rear takedown pin without requiring a full disassembly. It leverages insights from Chad Albrecht of School of the American Rifle, emphasizing the use of a modified 1/16 inch Allen wrench or a specialized tool to manage the detent. This method is particularly useful for AR-15 variants with collapsible stocks, offering a more efficient approach to maintenance.
