Analysis of Dispersion Measurements for the M16A1 Rifle with Chrome Plated Bore

Abstract

This report is a result of the higher than expected wear out rate of barrels used on the M16A1 rifle during its use in Vietnam. The wear out rate was due to the normal mechanical erosion plus the corrosive effect of the Vietnam environment. To correct this problem, it was decided to chrome plate the bore of all replacement barrels. The sample barrels selected from three manufacturers were fired until they were worn out with accuracy checks taken after each thousand rounds fired. The average value of the extreme spread measure of dispersion was used to establish acceptance and rejection criteria for new barrels and to establish the amount corresponding to a worn out barrel.
