Call Craig at J&S in lakeville, they are stocking dealers. It's kind of a different place, very clique-y, but they should have a few for you to fondle.
Also Element Arms in Becker has lots of Spikes parts. I picked up a lower today and will be building my first Spikes Tac AR in the next couple weeks, I cant wait!! Heres a link to a whole thread of pics. http://www.ar15.com/forums/topic.html?b ... 418&page=1
