Quoted:
I was contacted by Aeneas2020 and he had an older pinned style XM607 stock. I decided to jump on it after talking with my gunsmith. I also just ordered Nodak NDS-XM16E1 "Retro" lower receiver, NDS-42 standard charging handles, and NDS-603 "Retro" upper receiver for the build. The hard part about this build is the wait to get my SBR stamp. I have been told it is taking up to nine months. If anything, it gives me plenty of time to source out everything.
Edited to add: I have also downloaded my Form 1 documents and associated documents. At the rate Nodak Spud is going, I figure it will be next April or May before the receivers arrive. I hope it is sooner, but they stay backed up these days.
Merry Christmas of '14 then!
eta: I ordered a partial fence lower in....April I think, and have the stock, handguards, upper, and moderator. Thats my grail AR ever since reading about them when this forum was created.
