I just got my MPX stock today from Sig after waiting forever on my SBR paperwork....and it seems a bit short. I was expecting it to take up all the space in the groves. All the images I have seen and the demo I handled had it filling up the entire space. Is it just me or is the stock short?

I believe the problem is they wanted to make the stock universal to the MCX and the MPX. The MCX, being 5.56, has a much bigger ejection port. It uses up more of the real estate on that side, requiring a shorter rod.
I don't know that SIG has discontinued the MPX specific one. But, if they now have a "universal-X" one, I would bet that is the case.
Supposedly the shorter rods have the same extended length of pull, but I can't remember where I read that.
Just bought a factory MPX SBR @ the 1500. Now the agonizing months of waiting begin!
What is the barrel length?
