This is a fantastic offer from Arms East and I highly suggest you all take them up on it. If, however, you decide not to take them up on this and we (heaven forbid) get to the point where confiscation occurs and there is no compensation.....please strip your rifles to the serialized receiver and return only that piece (feel free to also chop it up for effect). After all, according to THEIR law, that is the only part that is truly regulated. Hang on to the rest of the parts, or if you don't have the need for them, sell them on the EE and get compensated from some other CGNer that is willing to sit on them.
But as has been said in this thread in others, our main priority should be to fight this ruling. This is only the first step in a very, very troubling direction.
