I bought one these uppers for my brother for a gift, and when we went out shooting and it out shot, not one, but TWO of my builds I knew that this was absolutely money well spent and I had to come back to pick one up from their National City store. I have an entry level upper from PSA, and one that I put quite a bit more into with a mix of Aero, Anderson, BCM, Strike and Blitzkrieg Tactical. I do not know if its the way I put it together or if the parts I have just do not work well with each other, but both of these uppers I bought from Firearms Unknown, one via website and the other was an in store purchase, seem to feel better when shooting and they are just so accurate. **One thing I have upgraded on the upper, was the BCG. When I went in to buy my upper, the sales person made me aware of a sale they had going on with a Nickel Boron BCG and I jumped right on it. For under $80 I got one of the better NiB BCG's I have seen, and now I have the original BCG as a back-up. (Nothing wrong with it, just a phoshate coating.) I was helped by Andrew and Grover and they were as easy to talk to as an old friend. Awesome store, quality parts.
All in All, when you look at QUALITY and the company backed warranty for life, this is one of if not the BEST deals you can find around. Keep it up guys!
