Engineer Design Test of 20-Round Plastic Magazine for M16A1 Rifles
Abstract
A series of engineering design tests of 20- pound plastic magazines of 6-10 nylon with 50% fiberglass reinforcement, for the M16A1 rifle was conducted. Equal numbers of test and control magazines were subjected to a series of comparative evaluations to determine function performance characteristics and material durability at 65 F, +155 F, and ambient range temperature (+70 F plus or minus 30 F), and in adverse conditions of mud, sand, dust, and water. The test magazine material was checked for compatibility with various nonstandard solvents and lubricants. A displacement time study was made of the magazines to determine cartridge positioning characteristics during firing. The test results reveal that the test magazine requires further design engineering to improve performance in adverse conditions and to increase material durability at low temperature.
