==Description==
The XM301 is a lightweight, three-barrel version of the M61 Vulcan. It is externally powered, relying on the same power delivery system as the Vulcan. It fires M50 and PGU-series ammunition found in the Vulcan, as well as newer lightweight X1031/1032 aluminum-cased ammunition at either 750 or 1500 rounds per minute.〔 Designed for use in combat helicopters, the XM301 boasts a dispersion of 2.2 milliradians, making it accurate at long ranges.〔 The XM301 weighs 80.5 pounds, less than a third the weight of the Vulcan. It can hold 500 rounds of ammunition, and is able to be field-reloaded in 15 minutes.〔 The turret allows an aiming range of +15° to -45° in elevation and ±120° azimuth. It may be stored at +2° in elevation and 180° azimuth in order to reduce radar cross-section.〔
