I never seriously considered getting one (might have if they were cheaper). But this is a bit disturbing, and only a tiny step from making all uppers 'firearms' (IMHO).

Calling President Trump. Please hollow out the ATF.

This is the camel’s nose under the tent. Today, uppers for .50 cal. Tomorrow, any other upper they care to list.

A .50 upper? How the hell do you feed a .50 BMG round through a .223 lower?

[DesertRhino]

They want to make all AR uppers firearms. I doubt if there’s been a single crime in America that involved a 50 caliber bolt-action rifle

The .50 Caliber Barrett has been Illegal in Commiefornia for a while, despite the fact that nobody ever used one in the Commission of a Crime.

Well, I can’t shoot ‘em with my uppers; but I can sure’n hell bite ‘em.

I think that the BAFT fear is that serious hobbyists can finish an 80% AR-style lower for personal use and that a 50 Cal rifle is something that they want to keep a little more control over. But that would be political not technical.

Recoil is also kind of an interesting issue. Not sure how a typical AR-style low end lower would hold up under the recoil of a 50 cal. The shoulder stock need to attach to the lower and even with a great muzzle break that is probably a lot of kick being transferred from the barrel/bolt through the lower into the shoulder stock.
