SmythBusters: Mounting Optics on Handguards
This video from Brownells' Smithbusters series demonstrates the critical impact of optic mounting location on an AR-15's accuracy. Hosts Steve and Caleb test mounting optics on the handguard versus the receiver, showing significant point of impact shifts and group opening after simulated stress. They conclude that mounting optics on the receiver is essential for maintaining zero and accuracy, especially in demanding scenarios.
