Smyth Busters: Are Bronze Brushes BAD for the Barrel?

This video focuses on the Brownells BRN PROTO AR15 Retro build. The description highlights an update on cleaning the barrel, noting that the chamber is still rough with some missing chrome. Initial cleaning removed firing residue and caked-up oil from the chamber. A follow-up video is planned after Christmas to showcase any differences achieved through further cleaning.

This guide debunks the myth that cleaning wears out a firearm barrel. It emphasizes that proper techniques and appropriate tools are crucial, especially for .22 caliber firearms with softer barrels. The video highlights the risks associated with residual ammonia-based solvents and recommends specialized products for precision shooters. Modern barrel treatments like chrome lining and nitriding offer significant durability against standard cleaning methods. Overall, copper fouling poses a greater threat to accuracy and barrel longevity than diligent cleaning.

This guide provides a comprehensive 101-level overview of firearm cleaning, drawing on the expertise of Iraqveteran8888's Eric. It covers essential safety protocols, proper disassembly, effective cleaning techniques for various firearm components, and appropriate lubrication methods. The video emphasizes the importance of regular maintenance for firearm reliability and longevity, akin to vehicle upkeep.

This guide details the process of deep cleaning a firearm barrel to restore accuracy and prevent malfunctions. It emphasizes safety, proper cleaning direction, and the use of specialized solvents for different types of fouling. The importance of inspecting the barrel with a bore light or borescope is also highlighted.

This video debunks the myth that new firearm barrels do not require cleaning. Brownells Gun Techs Steve and Caleb use a borescope to demonstrate that factory-new barrels, particularly AR-15s, often contain grease in the bore and chamber. This grease can cause extraction failures, pressure issues leading to malfunctions, and in extreme cases, a catastrophic weapon failure or 'KA-BOOM.' The experts advise a simple cleaning with solvent to remove this protective shipping grease before firing the first round, regardless of whether the barrel is a replacement or part of a new firearm.

This guide details the cleaning process for a Steyr Aug A3, covering the barrel, gas piston components, bolt and carrier, plastic parts, and trigger mechanism. It emphasizes a multi-step approach involving solvent, brushing, and dry patching to ensure thorough removal of carbon and debris. The procedure concludes with a final inspection before lubrication.

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.
