USFantastic combo!
All items arrived quickly and in perfect shape. The finish on the upper receiver is great, no blemishes and it matches my Aero lower very nicely. The preassembled gas block and gas tube are very nicely done. No nicks or scratches on the gas block from assembly. Nice work. The barrel is most definitely the high light of this package. Very nice muzzle threads and crown, as well as the finish. If you are looking for a nice combo to get you started on your first build, this is literally the best bang for the buck out there. I highly recommend this company and their products.
