I've bought from them twice and have been generally pleased. I think Model 1's E.R. Shaw barrels are top-notch, and I've never had any trouble with the upper receiver, sights, gas tube, etc. I thought that the basic plastic handguards on mine were a little loose, but I've seen that on other makes and they can be easily replaced anyway. The big thing is, if you're looking for a truly complete upper (i.e. with a BCG and charging handle) you can do much better by purchasing these elements separately. The BCG I got from Model 1 was functional but was not properly staked, chrome-lined, etc. Similarly, the charging handle seemed a little flimsy. I later sold these parts to a guy who knew what he was getting and was only looking to build a super-cheap AR15. I took that money (plus a little more) and bought a Daniel Defense BCG and LMT charging handle from other sources. I'm much happier with that setup now.
