Abstract:

Tests were performed to determine the accuracy of an Australian F89 light machine gun having barrels fitted with or without flash suppressors. The results of these experiments are presented in this report. It was observed that the addition of a flash suppressor from a MAG 58 machine gun can reduce the size of mean radius dispersion by as much as 41 over an original Minimi flash suppressor and 35 over none being fitted. It appears that when using standard taper-ended Minimi barrels 19 of this improvement can be attributed directly to the mass of the MAG 58 flash suppressor but that this mass has no apparent effect on accuracy when using heavier F89 barrels. It was concluded that gas- dynamic effects due to flash suppressor design may have a significant role in weapon accuracy and merit further study.
