That is incorrect. The agency concedes that it has amended the definition. See posts 112 and 153.
Whatever they say, if there's no practical legal result then the definition hasn't changed. Any basis for a challenge would depend on some kind of standing--if there's no practical change in legality then no one has been damaged, no one has standing and, clearly, the "amended definition" didn't change the law, it only clarified/amplified it.
I did not imply that his pistol was an SBR because it is not possible to show that it is legal using the rule.
If you don't believe his pistol is an SBR, then we agree that it is not. If you believe it is, then you would need to use the law to show how it fits the definition of an SBR.
Your "bottom line" about the presumption afforded a criminal defendant isn't a comment on the structure of the rule.
The law has to be used for something or it serves no purpose. If the government can't demonstrate that an action is illegal or an item is regulated/illegal then they can't move forward. That is the bottom line. They have to demonstrate how the pistol would fit the definition of SBR or it is not an SBR and isn't regulated as an SBR.
...leaves possessors and potential defendants poorly positioned to contest the result of the examiner’s discretion.
No more than with any other law. If the government claims that the pistol is an SBR because of X, Y, and Z, all the defendant need do is point out that X, Y, or Z does not apply to the pistol, or that X, Y, or Z is not a reasonable criteria for identifying an SBR.
No one needs to wonder whether it was “designed or intended to fire a weapon from shoulder” because the agency found that it wasn’t more than a decade ago.
This is where it gets humorous. You have attacked the validity/consistency/ambiguity of the opinions everywhich way possible but will use them to bolster your argument when it suits your purpose. Furthermore, the letters and the opinions in them have been invalidated so using them as a basis for argument is, at best, seriously problematic.
Besides, UNLESS those opinion letters changed the law, something you say the BATF is not allowed to do, then the NFA still applies and should be the only basis for evaluating the current rule. You can't argue that the rule expands the law compared to the now invalidated opinion letters because they have been invalidated and, more to the point, they were never law to begin with.
The problem may be easier to understand by analogy to speed limit signs.
Very good.
You CAN get a ticket, at ANY speed, if the issuing officer believes your speed is excessive for existing conditions.
Exactly correct. So is that law problematic because it depends on a confluence of circumstances rather than on a clearly delimited boundary? Of course not. Nor does it eliminate the ability to challenge/defend against such an accusation.
For instance, if the weapon has a scope, that alone can classify it as a rifle under the regulation, but not the NFA.
Absolutely incorrect. This kind of blatant mischaracterization of the law while you are in the midst of an argument that focuses heavily on semantics and specific wording makes me wonder about your motives.
Before any weapon can be classified as a rifle under the rule, it must have:
"...an accessory, component, or other rearward attachment (e.g., a “stabilizing brace”) that provides surface area that allows the weapon to be fired from the shoulder..."
That's only the first step. Then it
must have "other factors" as well.
One of those factors is a "scope
with eye relief that require the weapon to be fired from the shoulder in order to be used as designed..."
So not just "a scope" "alone". Not even an accessory, component or other rearward attachment providing shouldering capability
plus a scope. The scope must be one that is can only be used (due to eye relief limitations) if the gun is shouldered.
The two factors, a scope that is intended to be used when the gun is fired from the shoulder, plus provisions for shouldering the gun would certainly indicate that the firearm fits the definition of rifle under the NFA since the resulting firearm would certainly be "designed or redesigned, made or remade, and intended to be fired from the shoulder”.
