Well, that depends. I think SPEQ pricing is standard across the board, dealer to dealer. Everything that is in the SPEQ program comes from the factory with special serial numbers, and it all goes though one primary distributor. So I think each dealer has to run specific pricing on SPEQ items. How much you save is dependent on how good that dealers regular pricing is. On the Specwar 556 K I just bought it didn't seem like that much, because their std pricing was really good. But on the Spectre II that I got last fall, it was significant. Most of the items I looked at the pricing was enough better to make it worthwhile for sure.
Clear as mud?
Normally SPEQ is for active duty military and LE, plus disabled vets. Every now and then Sico opens it up to veterans with an honorable discharge. You will have to find a dealer that does SPEQ, and send them a copy of your DD-214.
