Match the barrel extension to the bolt, i.e., DPMS barrel (and barrel extension), then run a DPMS bolt.  Armatlite barrel, Armalite bolt.  <thumbsup>

The entire bolt carrier group of either flavor (DPMS or Armalite) will fit in any upper receiver, and run.  I've seen reports from guys that just changed out their barrel from one to the other design, and not had problems.  I've also seen reports from people that had problems running DPMS and Armalite parts together (barrels and bolts; example, just putting a DPMS barrel on a complete Armalite rifle). 

The best thing do do is keep those "meshing" parts together, because you can mount the barrels to the upper receivers without problems.  I've never (myself) seen any reports from people on the precision measurements of the two styles of bolts or barrel extensions - it might be out there in the web somewhere, but I haven't found it myself.

Thats exactly what I was thinking. I purchased another Armalite A2 upper, at a great price, and since Armalite barrels are hard to locate, I  figured I would ask. Great Info, that helps out alot, Thanks Pal.
