The objective of the study was to compare alternative solutions to correct the 5.56mm Blank Cartridge M200 malfunction rate. Several alternatives were evaluated to determine the expected time and cost to correct the problem. These alternatives included redesign the 5.56mm Blank Cartridge using brass, steel, and aluminum increase the length of the present M200 blank cartridge modify the 20-round magazine or use the 30-round magazine. Redesigning andor increasing the length of the M200 Blank Cartridge are the most expensive alternatives in terms of cost and time. The modified 20-round magazine is likely to solve the stubbing problem, but the introduction of another item into the inventory has met with user opposition. Based on limited test data, the 30- round magazine has demonstrated an acceptable stubbing rate 3. This is the low cost alternative because the 20-round magazine is currently being phased out and replaced by the 30-round magazine. It is recommended that a confirmation test should be performed by the user to verify the low stubbing rate of the M200 Blank Cartridge used with the 30-round magazine.
