Lots of guys "make" an AR from parts but here is one a little different. It started out as a little shop thearapy after my CNC went TU again a couple winters ago. Since I didn't have the money to buy another $1500 board at the time and the project I was working on really needed CNC, I took a break and went old-school milling out a billet upper and lower (less than $60 in materials on the upper and lower) on a bridgeport without DRO's and a manual lathe. Once I was into it that deep, I decided to make a ajustable stock and a handguard .... Barreled it with a cheapo green mountain 1-7 blank that I turned and chambered. All together the most expensive part was the optics - SS 16X followed by the bolt carrier and the JP trigger. Like to many of my personal shop projects it got placed on the back burner after getting it 98% done. Finally finished it a few months and am still debating if I like the GM barrel or if I will fit a decent tube, it wants to shoot at the beggining of a 10 shot group but will invariablely leak 1 or 2 out of a 10 shot group ruining what would have been a great .5-.7 moa group and bringing it out to 1-1.5 moa.
Dang sure learned a few things about stoners design staring at prints and remembered a few things I had forgot about machining and AR's....
