I have contacted Stag about availabiliy of striped 6.8spc roll marked lowers and 5.56mm.

this post is to see if a group buy could or would be viable. I work for a FFL and will have to have the final point of sale/transfer through the shop(Chicago Northwest Sub) to avoid any "straw" purchase issues. i still have to work out what kind of deal i could offer in pricing with my boss. if i could move a bunch at one time  this will help. like i said this is just to see if there is a demand great enough to make it worthwhile.

Any idea of cost?

well that is the issue. if i could get 1/2 a dozen people interested i think i could get the boss to allow some discount on retail. even more people would increase my ability to cut over the counter cost.
