If you're asking if the parts are made out of the right materials, and do they fit, the answer is yes. On the other hand, if you want to know if the finish and appearance is the same, the response is:
HELL NO!
Bushie parts beat DPMS into the ground by a huge amount; except for the DPMS hammers, which don't have notch in the top front and are smoother operating w/the uncutaway bolt carriers I use. Also, Bushie trigger guards are plastic, while the DPMS guards are aluminum, although the aluminum guards are usually semi shiny black and don't match the color of the lower receiver.
On the other hand, DPMS takedown pins and safeties are full of toolmarks, the hammer/trigger pins aren't chamfered at the edges, the bolt holdopen I got was totally out of spec and had to be thrown away, and the mag release button on the piece I got, while functional, was so ugly I scrapped it too.
All of which is why I don't buy parts kits.
I go to the show (going today in fact), see my favorite parts guy from Southeast Military Parts, and hand pick the pieces I want. Costs me a few bucks more, I suppose, but I'm happy w/ the stuff I get.
