Yes they are great to deal with. They have assembled a few uppers for me. The labor prices are reasonable and usually turn it around in a day or two.I asked the same question here several months ago. Bear Beam was suggested and it was the correct choice. I needed everything but a barrel for an upper half. They had it all. I went there believing that I would have to end up ordering a gas block since I needed one for a .625 barrel, they even had that.
