Never heard of a 2-position commercial buffer tube. Several years ago, Bushmaster had 3-position buffer tubes that were very close to commercial diameter, but not mil-spec. They had an aluminum CAR stock that was design to work with that buffer tube. I use to have one of these and sold it.
Have you tried to see if a mil-spec stock will fit on the buffer tube?
