Also, the fire control area was too tight and needed to be opened up a bit more in order to get the trigger assy parts in there as well as the trigger hole itself needed to be opened up more.

was that one of the ones they sold, or one that you brought in to be machined at their shop?

Are they DPMS or Armalite pattern on the .308 lower?

They are DPMS pattern, but you will need to do some tweaking to get them to work. I had to do a little work on the pin holes, the trigger housing area and the bolt stop area to get them to function properly.

Not at all related, but when I completed a lower, I also had to go back and rework the trigger area as I had done it too narrow the first time. It's a good idea to have an LPK on hand so you can check your work; however that might not be reasonable if you have a line of people waiting behind you or there are manufacturer issues with having materials on hand to complete lowers.
