Correlation of Breech Erosion Gage to Accuracy for M16A1 Rifle with Chrome Plated Barrel Bores

Abstract

This research is designed to answer the following questions: (1) do calibrated gage rods act as good predictors of the accuracy parameter of extreme spread for M16A1 rifles; and (2) what gage rod diameter gives the better performance for the M16A1 rifle. The data used to answer these questions were obtained from M16A1 rifles test fired at different firing rates for the life of the rifles. For each rifle and gage, the accuracy parameter of extreme spread was recorded with the corresponding gage reading at periodic intervals of rounds fired. The data were analyzed for a relationship between the extreme spread and the gage reading.
