Building (assembling) an AR is you have 100% of the parts sitting next to you and have a work bench and a vice is very fast. WAY under an hour. Funny this should be asked here and now because 2 days ago my friend from Lander came over and asked the same exact question.
He dropped off a full set of parts here and drove to Shoshoni to hook up to a boat and drive back. The town of Shoshoni is 10 miles from me and he took about 3 minutes to hook up to the boat trailer and drive back. 3 miles are dirt road so he'd drive at about 20 MPH on the dirt and the rest is highway on which he can go 70 MPH. He dropped off the parts, went to get the boat and I had the gun done and was zeroing it when he got back.
I should have looked at the time when he left and at when I was done building, but I did not.
However I can say it's less then the time it takes to drive 17 miles at 70 MPH and 3 at 20 MPH + the time it took to drop a trailer ball onto a hitch and chain it up, put in a plug and leave again.
