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 product spotlight video focuses on Aero Precision's Solus rifle barrels. It details available options, including different profiles like the M24 and fluted variants, and various calibers such as .308, 6.5 Creedmoor, and 6.5 PRC. The description highlights key features like 416R stainless steel construction, Elite Cerakote finish, and precision machining. The video also touches upon muzzle threading, recessed crowns, installation without a barrel nut, and compatibility with Zermatt and Bighorn actions, making it valuable for precision rifle builders.
This video from Brownells Gun Techs Steve Ostrem and Caleb Savant explains the process of "breaking in" a new firearm barrel. They detail how microscopic burrs in newly machined rifling can be smoothed out by firing bullets, preventing copper fouling and improving accuracy. The video clarifies that this process is most beneficial for cut-rifled and button-rifled barrels, while cold hammer-forged, chrome-lined, or nitrided barrels (common on AR-15s) and pistol barrels generally do not require break-in. Smaller caliber rifles are also noted to benefit more than larger calibers.
This YouTube video features a Q&A session with Nathaniel from Faxon, delving into the intricacies of barrel manufacturing. The discussion highlights the differences and pros/cons of nitride versus chrome lining treatments for firearm barrels, touching on their impact on accuracy and durability. The video also explores the history and evolution of barrel manufacturing processes, including cold hammer forging and cut rifling, as well as advancements like button rifling and progressive twist rifling. The discussion extends to the metallurgy of stainless steel barrels and the potential benefits of nitride treatment for other firearm components.
