What is the halflife of an M16?
Of course, "halflife" is not the correct term to use in this context, so I am supposing that you are asking how long as in "how many years of use" or "how many rounds fired" can you expect an M16 to function. This is also called "service life". The answer depends entirely on how the machine is treated. If it is properly cleaned and has minor parts replaced as they wear and break, the rifle will last for many years and/or many tens of thousands of rounds. You can research the endurance testing that the US Army has employed to determine the tolerance to hard use. "Halflife" refers to radioactive material and is the amount of time required for half of the material to decay.
