These have been on sales since August I believe, and I finally ordered two of them. Picked them up this morning from the FFL, and they are very high quality lowers. I don't care for the color fill on the Spikes logo, but opted for the fill on the safety selector.
Caliper marked 'Multi' which gives me flexibility on the build. My first order with Spikes, and I have to say they made this very painless. Very quick to ship (4-days from order to delivery), high quality item, excellent price, and e-mail notification for tracking.
