The attachement I had added addresses buffer tubes to a point, atf points out that it only standard buffer tubes will be considered in OAL measurement and not a tube like the KAK supertube that has about an inch of superfluous material or so of solid space added to the end which does nothing but add length to extension. An A-5 or AR-10 tube which is longer than an AR15 tube but are fully functional may end up being another "gray" area which those are standard receiver extensions just not necessarily for an AR15. In the end any LEO can crack your nuts until they get themselves sorted out so you may beat the charge but you might take a ride.
