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 disassembly process for the gas trap variant of the M1 Garand, highlighting its differences from the later, more common models. It involves removing the bolt and operating rod first, then a specific screw to release the gas trap, followed by the sight block, before the gas trap assembly can be rotated off. This early design proved less reliable than the later gas piston system.

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.

Roy Huntington demonstrates the process of bead blasting stainless steel 1911 parts to achieve a uniform satin finish. The video highlights the use of a modified Harbor Freight bead blasting machine and glass beads, emphasizing the importance of circulation for consistent results. This technique is presented as a valuable method for improving the aesthetics and uniformity of firearm components.

This guide details a specific trick for disassembling the Smith & Wesson M&P9 (1.0 model) for cleaning. It highlights a common point of confusion where standard field stripping methods fail on this older version. The key is using a tool to manipulate an internal lever after locking the slide back, a detail often overlooked but crucial for successful disassembly. Instruction comes from an experienced source demonstrating clear expertise in M&P platform nuances.

This guide details the installation of a Geissele MK8 Super Modular Rail on an AR-15 platform. It covers securing the upper receiver, installing the barrel nut, gas system, and the rail itself, emphasizing the use of specialized tools and proper torque specifications. The process requires an intermediate skill level and careful attention to detail for a secure and functional build.

This guide, based on expert instruction from Brownells, details essential practices for proper ammunition storage. It emphasizes using airtight containers, managing humidity with desiccants, and maintaining stable temperatures to ensure ammunition reliability and safety. Proper storage is crucial for preventing corrosion and propellant degradation, especially for sensitive components like primers.

This guide details the process of upgrading an AR-15 from standard A2 furniture to Magpul components. It covers the removal of the A2 pistol grip and installation of the Magpul MIAD Grip and Magpul PRS Stock. The video demonstrates efficient assembly using specialized tools, highlighting the ergonomic benefits and adjustability of the Magpul parts. Instruction is provided by Brownells, a recognized industry authority.

This entry details the creation of a movie prop suppressor for a Remington 11-87 used in 'No Country for Old Men.' Prop master Larry Zanoff explains how the suppressor was designed to look homemade and was non-functional, with sound effects added in post-production. The process highlights the creative problem-solving involved in film armory.
