Abstract:

Four each of the XM12 blank-firing attachments BFAs for the M14 rifle, and MX13 for the M60 machine gun were furnished for this test. Weapon-functioning tests and extreme-temperature tests were conducted with each BFA-weapon combination using Cartridge, Blank 7.62-mm, XM82. In addition, one round of Cartridge, Ball, 7.62-mm, M80 was fired in an M14 rifle with the XM12 BFA in position to determine if the resulting fragments would endanger a rifleman. It was determined that the experimental BFAs XM12 and XM13 would satisfactorily operate the weapons for which they are intended with the XM82 blank cartridge at ambient temperatures above 0 F. At lower temperatures, operation of the BFA-weapon-cartridge system was marginal to unsatisfactory. Serviceable life of both types of BFAs was influenced by the relative severity of the firing schedules employed. The distribution pattern of the fragments produced by firing an M80 round through an XM12 BFA indicated that the rifleman would not have been endangered in this instance. However, the BFA and flash suppressor were rendered unserviceable and the rifle barrel suffered a slight bend at the muzzle approximately 0.008 inch. Author
