Gun Gripes #345: "Are 7.5 Inch ARs Useless?"
This video critically examines the utility of 7.5-inch AR-15 barrels, concluding they are impractical for serious use due to significantly reduced 5.56mm velocity and terminal performance. While offering a 'fun factor' for range use, they suffer from reliability issues and are outperformed by calibers like .300 Blackout in short configurations. The speakers recommend at least 11.5-inch barrels for practical applications.
