How Powerful are Short Barrel AR-15s?
This video tests the ballistic performance of a short-barreled AR-15 pistol (7.5-inch barrel) against a standard 18-inch rifle. Results show a significant velocity reduction of approximately 26% in the short barrel compared to the longer one, with the 7.5-inch barrel averaging 2203 fps versus 2977 fps for the 18-inch barrel. The build features components from Anderson Arms, Ground Zero Precision, Shockwave Technologies, Midwest Industries, and a Holosun optic, with a Griffin Armament suppressor.
