True, I argued with my buddy last weekend about an AOW he had built. Yes, it was off a virgin receiver, but he said he did a transfer not a form1. I told him he need to correct the situation because I was unaware than remington ever made an AOW and if BATFE was to drill deeper into it, they could come back and nail him for it.
CAR-AR-M16, also, correct me if I am wrong, but when doing the Form 1 on an AOW build, you still need to go through the engraving schtick too, correct?
If he had it built by a class 2 mfgr. it would be tranfered to the individual on a form 4.
Rem and Mossberg sell virgin rec.s to class 2 mfgrs.
All post 68 class 3 items no matter who builds it must be engraved or stamped with the makers name, city and state and serial number.
Now on some collector pieces finding where they stamped may not be noticable, because BATFE let them hide it inside the rec or on the bottom of the barrel so as to not affect the collector value.
