switching caliber uppers on SBR

Post by Orlando Paulitician » Fri Dec 15, 2017 7:10 pm

I went to a local FFL (I won't name drop because the last time I did that, the person took it way to personally [smilie=011.gif] ) to get a fostech installed on my SBR.

I keep my rifle in the configuration stated on my paperwork, 10.5" 5.56, but I sometimes swap on a 9" 300blk for range fun.

FFL said I was committing a felony by doing that. He specifically said that switching the caliber to something other than that stated on the form is wrong.

I know he's wrong because NFA law makes no mention of switching calibers on an SBR-registered item. Furthermore the only mention I can find of calibers being regulated would be destructive devices for calibers over a certain size, of which .30 cal is not.

Problem is, people who are this ignorant never take, "Well, the law doesn't specifically state that X activity is illegal, therefore it's legal until proven otherwise". Their mentality is like that of an obedient dog, they have to be told by those with authority that X is ok before they believe X is legal.
Cliffs: So, does anyone know if there's an ATF letter explicitly stating switching calibers is legal?

I found a letter which proves switching uppers (SBR length to rifle 16"+ length) is legal, the logic of which proves my point (SBRs are defined as a rifle with a barrel or barrel(s) of less than 16"). But a person has to be reasonable and willing to actually exercise judgment in order to validate logical arguments.

Your FFL is full of [smilie=042.gif]

Permanent changes = Notify* ATF.

Temporary changes = Party on.

If I had a dollar for every wrong piece of advice/law I overheard/received while at a gun-shop, I'd be able to afford a small island in the Caribbean.

You're just as guilty Mike ......you just gave him advice without posting a specific ATF letter or ruling in which he was asking for
In the days of the old west a 6 shooter was as common as cell phones are today and just annoying if they go off in a theater.

Because there is no ATF letter...nor any section of the USC forbidding it.
