Mike from SOLGW breaks down key features including the rifling, materials used, gas port design, barrel profile, and muzzle threading. The video emphasizes the quality, quality control, and craftsmanship of SOLGW barrels, asserting that their PRECISION barrels are the most accurate they have ever offered. It encourages viewers to consider an SPR barrel for their next custom precision rifle build.

This 'I Have This Old Gun' segment from American Rifleman Television delves into the history and unique design of the British Brunswick rifle. It highlights how the Brunswick rifle, positioned between the iconic Baker rifle and the revolutionary Enfield, addressed the loading challenges of earlier military rifles. Unlike traditional rifling, the Brunswick employed two deep grooves in the barrel and a corresponding ring on the bullet for a mechanical fit, a system previously not used to a great extent in military arms. The video aims to tell the story of this distinctive firearm.

This video provides a detailed look at the Lyman Borecam 2.0, a bore scope designed for inspecting firearm barrels. Caleb from Brownells demonstrates the unboxing process, setup, and highlights key features such as adjustable lighting and smartphone connectivity for capturing photos and videos. The tutorial covers inspecting rifling, gas ports, and chambers, making it a valuable tool for shooters and gunsmiths seeking to maintain and understand their firearms' internal condition.

This video details the meticulous process of manufacturing rifle barrels at Green Mountain Rifle Barrel Co. It covers everything from sourcing raw materials like 4140 and 416R steel to advanced techniques such as deep-hole drilling, reaming, cut rifling, and button rifling. The production emphasizes precision, with critical steps like chambering and crowning highlighted for accuracy, and includes quality control measures like bore scoping and air gauging.

This video, a re-edit of an original from May 13, 2024, focuses on the process of rifling firearm barrels. The creator plans future, more in-depth rifling videos, including one specifically on ECM rifling. They tease an upcoming short video demonstrating a quick, albeit potentially 'ugly' or 'epic,' method using inexpensive Chinese rifling buttons, grease, and a hammer. Links to American-made rifling buttons from Danjon and DME Tool are provided.

This video details the spin stabilization mechanism of a 106mm recoilless rifle, specifically the M40A1 model. It highlights how the M346A1 cartridge's driving band engages with the barrel's rifling to impart rotation. The internal rifling is crucial for maintaining projectile accuracy and stability over distance, with clear visual evidence of the barrel's spiral grooves and weapon markings.

This video details the industrial button rifling process for Savage rifle barrels. It covers essential steps like tool preparation with specialized lubricants, precise machine alignment, and the cold-forming of lands and grooves by pulling a rifling button through the steel bore. The process concludes with post-production inspection and collection of finished barrels.

Jonathan Ferguson of the Royal Armouries explores the history and design of duelling pistols, revealing that many 'duelling' features were simply good pistol design, and the term gained popularity later. He discusses how some pistols incorporated hidden rifling, like 'French rifling,' to provide an unfair accuracy advantage while appearing smooth-bore, contradicting duelling rules. The video highlights a specific cased set of Mortimer & Son percussion pistols from circa 1820-1822.

This video debunks the myth that bronze bore brushes damage modern firearm barrels. Experts Steve and Caleb from Brownells explain that bronze is softer than modern barrel steel, and damage is more likely caused by cleaning rod flex or hard steel brush cores. They recommend nylon brushes or high-quality bronze brushes used with bore guides for safe and effective cleaning.

This video provides an in-depth look at the internal structure of a .50 BMG rifle barrel, featuring a cutaway section. It demonstrates how a .50 BMG round seats in the chamber and how the bullet engages the rifling. The barrel section also features personalized engraving from gun designer Mark Serbu.

Choosing the correct AR-15 barrel is paramount for accuracy, durability, and reliability. Key factors include defining the rifle's purpose (General Purpose, Long Range, CQB) as this dictates trade-offs in barrel length, profile, material, and gas system. Understanding legal barrel lengths and configurations (SBRs, pistols) is crucial, as is selecting appropriate materials like 4150 Chromoly or 416R Stainless Steel with protective linings such as chrome or Nitriding. Barrel profile impacts heat management and handling, while rifling methods and gas system length affect performance and tuning.

This video serves as a teaser for an upcoming fourth installment in a rifling series. It briefly touches on the theory behind rifling buttons and showcases a newly acquired hydraulic rifling machine. The creator also includes a passionate plea for Patreon support, outlining how increased funding would enable professional production and enhance the channel's content, including hiring a cameraman, sound engineer, and editor, and acquiring a mansion, jet, and Ferraris.
