This guide, presented by Josh from AT3 Tactical, explains the fundamental concepts of AR-15 barrel rifling and twist rates. It details historical methods, modern manufacturing processes like button rifling, cut rifling, and cold hammer forging, and clarifies how twist rate impacts bullet stability based on weight. The information is presented with an emphasis on practical application for firearm owners.

This guide details the intricate manufacturing process of the L1A1 SLR rifle, as presented by Jonathan Ferguson of the Royal Armouries. It covers the extensive machining, heat treatment, and quality control steps involved in creating the rifle body, barrel, breech block, trigger housing, furniture, and magazines, culminating in rigorous testing and packing procedures. The process highlights the precision engineering and labor-intensive operations required for military-grade firearm production.

This guide covers the operation and basic maintenance of the Baker Rifle Pattern 1800, a pivotal firearm for Napoleonic Wars sharpshooters. It details loading procedures with specific powder and ball charges, sight usage for extended range, and emphasizes the trade-offs between accuracy and reload speed inherent in rifled muskets of the era. Expert instruction highlights the rifle's historical significance and technical features, including its unique rifling and markings from the Tower of London.

This guide details the loading procedure and basic maintenance for the Baker Pattern 1800 Rifle, a significant firearm from the Napoleonic Wars. It covers the standard load of 95 grains of 2F black powder with a .625 caliber round ball, and highlights the rifle's unique seven-groove, square-bottomed rifling and its patch box. The information is presented with the authority of Ian McCollum, a recognized expert in historical firearms.

This video provides an in-depth, data-driven review of the Proof Research 16-inch AR-15 barrel, featuring rigorous 30-shot group testing with multiple ammunition types. Instructor Preston Moore, demonstrating high expertise through detailed mechanical inspections and borescope analysis, concludes that this barrel is among the most accurate tested to date, consistently outperforming competitors.

This video from GUNBROS explains the concept of firearm twist rate, its importance for projectile stabilization, and provides historical context comparing smoothbore muskets to rifled rifles. The speaker, demonstrating high authority, details how twist rate affects heavier or longer projectiles and contrasts the effectiveness of the Brown Bess with the American Kentucky Rifle.

This video explains the cold hammer forging process for firearm barrels. It contrasts this method with traditional barrel making, highlighting how cold hammer forging preserves the material's grain structure, leading to increased barrel lifespan. The process involves using a mandrel to form the barrel's interior diameter and rifling by hammering the material from all sides.

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 explains the principle of spin stabilization in firearms, specifically demonstrated with a 106mm recoilless rifle. It details how the projectile's driving band engages with the barrel's rifling to impart rotation, crucial for accuracy. The expert-level explanation highlights the technical interface between ammunition and the weapon's mechanics.

This video explains how to assess the condition of a firearm's bore, a critical factor for collectors and shooters. It details a 1-10 rating system based on brightness, rifling depth, and edge sharpness. The presenter demonstrates how bore condition can impact accuracy, though less so at very close distances, and discusses how to interpret signs of wear like 'frosting' and corrosion.

This guide, presented by a firearms instructor, details the critical relationship between AR-15 barrel twist rates and bullet stabilization. It explains how twist rate affects accuracy with different bullet weights, covers historical context from the M16 to modern ARs, and provides practical advice for selecting the appropriate twist rate for various ammunition types, emphasizing the 1:7 twist's versatility.

This video details Daniel Defense's proprietary hammer forging process for creating high-quality rifle barrels. It explains the journey from raw bar stock through gun drilling, CNC profiling, hammer forging to impart rifling and strength, chambering, and final assembly with barrel extensions and gas ports. The process emphasizes mechanical hardening and molecular condensation of the steel, resulting in more durable and accurate barrels.
