This guide details the process of replacing the mainspring on a Swiss Luger 1900. It covers identifying a failed mainspring, the correct direction for removal, manipulating the grip safety, compressing and installing the new spring with safety precautions, and reassembly. The new spring is noted to be significantly stiffer, requiring a specific operational technique for this model.

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 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 fitting and trimming an aftermarket rail intended for a 6-inch barrel Colt Python to a 4-inch barrel model. The primary challenge is the difference in barrel ramp angles, which prevents a flush fit. The process involves cutting the rail to size and applying a finish to the exposed metal.

This guide details the installation of Slick Shot stainless steel nipples on a Pietta 1860 black powder revolver. The upgrade aims to improve reliability by preventing cap fragments from jamming the cylinder and potentially enhancing ignition consistency due to a larger internal passage. The process involves unscrewing old nipples and installing the new ones, with a specific note on using Remington #10 caps.

This guide addresses the auto-ejecting issue in the Ross 1912 Cadet rifle, as explained by Ian McCollum of Forgotten Weapons. Auto-ejection is not a designed feature but a symptom of worn locking surfaces. If your rifle exhibits this behavior, it requires attention from a gunsmith. Proper maintenance and understanding of the rifle's mechanics are crucial for safe and reliable operation.

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.
