AR-15 Platform VelocityTest: 7.5” vs 10.5” vs 16”?

Published on December 13, 2024
Duration: 8:26

This video compares the muzzle velocity of 5.56x45mm 55-grain Federal ammunition fired from AR-15 platforms with 7.5-inch, 10.5-inch, and 16-inch barrels. The test utilizes a Garmin Xero C1 Pro chronograph to record precise velocity data, demonstrating the significant impact of barrel length on projectile speed. The presenter, Mr. Madness, provides insights into the performance differences observed across the tested configurations.

Quick Summary

A velocity test comparing AR-15 barrel lengths showed significant differences: a 7.5-inch barrel averaged 2100 fps, a 10.5-inch barrel averaged 2400 fps, and a 16-inch barrel averaged 2800 fps when firing Federal 5.56x45mm 55-grain ammunition.
