they have got in some military surplus uppers.
you can get a pretty nice deal on some slicksides and a1 configuration uppers.
i just rolled the dice on three of their $20 junkers if they are really junk i'll at least get the forward assist assemblys of them and cut my losses. but JSE says there functional except for the sights--we'll see--LOL
PS they have all grades of uppers from new in wrap for $120 to used but very good for $50-$60--
