Smyth Busters: Do You Need Backup Sights on Your AR-15?
This video debunks the internet myth that quick-detach (QD) mounts are essential for AR-15 backup sights. The host, Steve, argues that some optics, like certain Aimpoint red dots, are short enough not to obstruct rear backup sights even without a QD mount, rendering the need for QD less critical in those cases. The discussion centers around the practical implications and necessity of backup sights for AR-15 platforms when using primary optics.
