Recommended AR Assembly Grease - Aeroshell 64/Aeroshell 33MS

This video reveals industry secrets, highlighting that Sub-MOA accuracy claims can be misleading due to non-standardized testing. It emphasizes that proper action screw torque is critical for consistent rifle performance, often overlooked in mass production. The speaker, presenting with high authority, debunks myths like mandatory barrel break-in routines and warns against damaging muzzle crowns during cleaning.

This guide details the process of lapping an AR-15 receiver to ensure proper barrel alignment for improved long-range accuracy. Instructor Stephen Caleb from Brownells explains that receiver faces can be slightly out of alignment, leading to barrel runout. The process involves using a specialized lapping fixture and aluminum oxide lapping compound with a drill to create a perfectly flat receiver face. This ensures the barrel seats flush and square, critical for precision shooting beyond 500 yards.

This guide details how to reload budget-friendly 223 Remington ammunition using Berry's 55 and 62 grain bullets and Accurate 2520 powder. It covers component selection, progressive press setup, load data considerations, field testing with a chronograph, and cost analysis, highlighting significant savings by reusing brass. The presenter, Serena, brings over 10 years of competitive service rifle experience and extensive behind-the-scenes work at Ultimate Reloader.

This guide details the installation of an AR-15 buffer tube using the LAW Tactical Alignment Tool (LAT) in conjunction with a Geissele Reaction Block. Expert instruction from the School of the American Rifle demonstrates how to achieve perfect alignment of the receiver extension with the lower receiver, crucial for proper function and preventing common assembly errors. The process involves securing the components, torquing the castle nut to 38-42 foot-pounds, and ensuring a reliable build.

This guide details the process of building a retro AR-15 clone inspired by early 2000s SWAT firearms, focusing on the 'SWAT gun' build. Key elements include sourcing a police trade-in Colt AR-15, integrating a Surefire handguard with a built-in light, and mounting a 1.5x ACOG optic. The emphasis is on aesthetic authenticity and the 'cool factor' of early tactical accessories.

This expert guide from the School of the American Rifle details how to identify and address rough carrier key bores in AR-15 bolt carrier groups. The instructor, demonstrating expert knowledge, explains how these manufacturing defects, particularly on Colt components, can lead to premature wear on the gas tube and reduced reliability. Solutions involve replacing the defective carrier key to ensure smooth operation and longevity of the firearm.

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.
