0004590: GAU-19/A should have a higher rate of fire

Notes
(0011481) tonimontana0328 (reporter) 2021-02-26 11:49	GAU-19As firerate is selectable to be either 1000 RPM or 2000 RPM. The current 1300 RPM firerate is only for the HMMWV GAU19A conversion kit. https://ndiastorage.blob.core.usgovcloudapi.net/ndia/2005/garm/tuesday/stgermain.pdf [^] Page 5 https://web.archive.org/web/20090323071502/http://www.janes.com/extracts/extract/jalw/jalw2943.html [^] "The GAU-19/A is designed to accept standard NATO .50 caliber M9-linked ammunition. The rate of fire is selectable to be either 1,000 or 2,000 rounds per minute. The Humvee armament kit version fires at 1,300 rounds per minute" https://en.wikipedia.org/wiki/GAU-19 [^]

The guys behind the MELB mod must have set that fire rate for a reason. The lighter GAU-19/B that was developed for late OH-58 blocks a couple of years before the AH-6J-to-AH-6M upgrade, was likewise limited to 1300rpm, and the rate on GAU-19/A has been adjusted for other uses where vibration was a problem on small platforms similar to AH-6 (1250rpm for Naval use, and as previously mentioned 1300 for HMMWV use). 1300 seems to have emerged as the optimal rate for the weapon since the 2010s. I just can't find sources that categorically state if the gun's fire rate is limited on AH-6 vs the full rate it enjoyed on the MH-60 and CH-47. Only that it doesn't seem to have been equipped on the AH-6J until the 2000s GWOT created an urgent operational requirement, and became a standard part of the Littlebird's arsenal with the AH-6M
