That shop in ca that has you just press the little green button is technically illegal. and any shop that would have you hit the little green button would be idiots and be in trouble if caught. I dont think it would be worth that shops business to let people do thing like that. dude I woudlnt do it for 20k cash or 40k in hookers and blow.
your better off doing it in your neighbors garage get a bp and you wont mess up.
I must be mis-describing it. The shop I was going to use does build parties 5 days a week. They do AR-15s, 1911s, and AR-10's. I did notice I would still be doing some of it by hand (not on the CNC machine).
Here is a quote from someone who did go there..
It was an easy, painless experience. I mounted the lower, pushed a button, then after the FCG pocket was done I went to a drill press and using a jig I drill the holes for the trigger pins and the safety hole.
I've also found other shops in Ca that do it (farther north).. Apparently its somewhat popular in Ca since buying an Ar-15 already completed has many more limitations.
This is from their FAQ..
How much does this cost?
The 80% Products price is listed on the product page of each item. If you are going to make use of our “hosted build party” you will be charged 65 dollars PER LOWER by the machinist to instruct you on how to complete it.
What happens at a build party?
You take your 80% lower to a Machine Shop. You then put the lower in the CNC Machine and press start.
