Are the standard receiver extensions / buffer tubes -(therefore stocks) interchangeable between the AR-15 and the AR(10)308 variants?

yes you can use ar-15 buffer tubes on ar-10/308s.   just get the right buffer and spring to go with.   The rifle tubes themselves are the same.   In carbine tubes come in 2 lengths, AR-15 and AR-10, which is a little longer.   You can use an AR15 tube on 308, but again with the correct buffer.   In DPMS 308, they use ar15 tubes.

I am using an ACE LTD buffer tube (commercial) and 6 position stock on mine.  I ordered the carbine buffer and spring from Fulton Armory and it works great.  Slash is on here and sells a buffer too, I assume it is to correct Failure To Feed issues, but I haven't needed it yet.  I also saw on The firearms Blog that there is a hydraulic buffer available Hydraulic Buffe  but it looks like it's for rifle length tubes only.
