There are other factors involved when in comes to a government contract going through or not on the purchase of equipment.
Guess what the main one is? MONEY.
Second, I'm guessing would be ability to produce required quantities in a certain amount of time with said locked budget.
Just because a product is effective does not mean the purchaser MUST ONLY buy that. After all, look at how many people keep buying CA, ICS and G&P guns over TM....
