This video offers a manufacturer spotlight on Sons of Liberty Gun Works (SOLGW), featuring an interview with founder Mike Mihalski. The discussion delves into the company's philosophy behind building premium-grade AR-15 rifles, emphasizing the barrel as the core component and the critical role of proper gassing for optimal performance, especially when using suppressors. Mihalski shares his journey from a dedicated AR shooter to a manufacturer focused on creating duty-grade firearms that withstand hard use. The interview also touches upon SOLGW's commitment to customer engagement and active support for the Second Amendment, framing the company as more than just a rifle maker but a cause. Hints about future product developments are also provided.

This in-depth analysis of an Anderson Manufacturing AR-15 barrel reveals significant quality control issues. Headspace was found to be short, and chamber mapping indicated constrictions causing potential extraction problems. Borescope inspection showed chrome flaking and a poorly machined muzzle crown, despite the barrel being chrome-lined.

This video from InRangeTV features a deep dive into firearm barrel technology with Faxon. Topics covered include the determination and manufacturing of twist rates, their impact on bullet stability for various calibers, and the practical implications of different twist rates (e.g., 55 grain bullets in a 1/7 twist). The discussion then moves to stress relieving techniques, including thermal and cryogenic treatments, and what to look for in a properly stress-relieved barrel. The video also touches on historical barrel quality, lead lapping, the concept and necessity of barrel break-in for different shooter types (average vs. bench rest competitors), and the impact of gas port size and location on rifle function.
