Smythbusters: Are AR-15 Rear Sights Interchangeable?
This "Smythbusters" video from Brownells debunks the myth that AR-15 rear sights from different manufacturers are not interchangeable. Gunsmiths Steve Ostrem and Caleb Savant explain that AR-15 rear sights are manufactured to a standard height, ensuring compatibility. They clarify that if a current rear sight works with a front sight, a replacement will also work. The video highlights the AR-15's versatility through easy parts interchangeability but cautions that this applies to current production models, with variations existing in older or retro reproductions. Viewers are encouraged to leave comments with questions or exceptions to this rule.
