PRODUCT IMPROVEMENT TEST OF MODIFIED AR15 RIFLES

Abstract

This report describes the tests of five AR15 rifles which incorporated the following modifications: the charging handle grip enlarged, the bolt closure-device plunger-head area increased, and three firing pins with inertia retarding devices. The weapons with modified parts were subjected to adverse conditions and endurance tests. Data recorded during testing indicate the charging handle and bolt closure device functioned satisfactorily; however, minor design and fabrication changes are recommended to increase the serviceability of the parts. A firing pin inertia retarding device appears to be unnecessary.
