This product spotlight by Brownells Gun Tech Caleb focuses on the SOTAR Cam Pin (SCP) from Forward Controls Design. Developed in conjunction with Chad Albrecht of the School of the American Rifle (SOTAR), this upgraded AR-15 cam pin features a unique dimple for consistent indexing during Bolt Carrier Group (BCG) reassembly. This consistent orientation promotes even wear on the cam pin, extending its service life and, consequently, the overall lifespan of the BCG by preventing accelerated wear on other components. The video highlights the importance of this seemingly small part in maintaining the reliability and longevity of an AR-15.

This video delves into the intricate workings of Eugene Stoner's AR system, commonly referred to as 'gas impingement.' It clarifies that the mechanism actually utilizes a cleverly integrated gas piston within the bolt carrier. The explanation details how gas is drawn from the barrel and travels to the rear of the bolt carrier, where it acts as a piston. The video also touches upon the benefits of this design, such as improved harmonics and reduced weight, and debunks the myth that the system vents directly into the magazine or chamber, highlighting its proven reliability. The description also promotes the creator's first book and Patreon page.
