Thanks to a friend of mine for alerting me to an issue concerning Safety Harbor Firearms and other manufacturers of .50 cal uppers. These manufacturers received a letter from the ATF. The letter claims that bolt action .50 cal AR uppers can possibly be considered firearms. I reached out to Walter Keller of Safety Harbor Firearms and he agreed to share the letter with TFB.
(Snip)
Then they segue into bolt action rifles. If you think of a traditional bolt action rifle, the serialized portion of the gun is the barreled action. So now the ATF is saying a bolt action upper assembly should be classified as such regardless that it sits on a serialized AR lower.

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?
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
YOU DON'T:
Single shot bolt action, loaded through the top. (I's seen some bolt repeaters with a magazine from the side as well, they cost a lot more.)
I'd be surprised if many (if any) crimes have been committed by people who swapped regular AR uppers, much less the Bolt action uppers.
I just had another evil thought, but I don't want to give them more evil ideas.
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.
They don't like the idea that somebody can acquire the ability to shoot a .50 BMG without a paperwork trail.
Well, I can’t shoot ‘em with my uppers; but I can sure’n hell bite ‘em.
Heh; Took me a second, but Heh.
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.
Barrett has quit selling their rifles to Kaliphorniastan LEO departments.
Point one- ATF control over a 50 cal upper- agree with that idea, the AFTE is deep state to the hilt, Trump has not dealt with them as needed. The entire DOJ is rogue in my opinion.
Point two- the AR lower bears no recoil impulse in regards to structural requirements. The buffer tube/receiver extension and the upper rear face transfer all recoil, the take down pins simply hold the lower to the upper.
Using a decent brake ( witch in a light weight 50 cal is a given) felt/free recoil is not much more than a 12 gag 3 inch mag load- maybe 45-50 ftlb, less than a 416 Rigby or 458 Win in a similar 8-9 lb rifle.
a 416 or 458 is WAY more than 45-50 ft lb in an 8-9 pound rifle! a 416 with heavy loads is closer to 80 in a 9 or 10 pounder. A 50 BMG at 30 pounds will be less, I’ll give you that one.
Umm, no, free recoil for a 416/400 at 2400 is 58 ftlbs in a 9 lbs rifle. How do I know? My Ruger No1 and a free recoil calc tells me so. Chiropractor in a cool package....
The Win 70 458/500 at 1975 ( never found a factory load that actually reached the advertised 2150 from it’s 24 inch bbl) is nearly the same, but less sharp. Both are easy to shoot, but certainly not like your 223.
Best
The Barret XM 107 (M82) with 30 in bbl at 24 lbs with optic is much less of an issue, but blast is the biggest uncomfortable aspect- the break works by moving gasses laterally and rearward.
The worst felt recoil I enjoyed was from my m’s P17 Enfield with feather weight bbl and very thin stock-6lb, left bruises like no other rifle- in 30/06; no wonder she didn’t shoot it much, 5-3/120lbs gal.
The worst recoil for me was from my Mossberg 12 gauge with a 16 inch barrel. 3-1/2 magnum slugs.
I was done after 3 rounds. So was the laser I had clamped to the barrel.
