My reply was in reference to the claim it also would be the upper going forward. I have not yet seen anything in the doc stating the upper would become a regulated part.
Ahhh ok that was my point.
I think, and this document is hundreds of pages I don't have time to analyze, everyone who are saying uppers will be serialized is doing so based on the split receiver stuff but haven't noted or are intentionally ignoring where they talk about already known/decided models.
Some folks haven't read that far, other organizations I think know but want to cause panic and gain support - like that GOA communication where they want donations.
I have no love for for this bullshit, but details about AR uppers do not seem to be changing based on this document. There are other things to get up in arms about.
But it is true, we really won't know what they actually say everyone needs to do for a couple months. They might re-approve a bunch of the p80 kits on the market today for instance as "not a firearm", doesn’t seem like they will, but they could. Or they could randomly pick at some common gun parts 2 years down the road.
