"With respect to barreling and the assembly of pistols, if the individuals utilize a receiver that has never been barreled as a rifle action, they may lawfully assemble a pistol. Such an assembled pistol would constitute a "firearm" as defined by the GCA. If an individual utilizes a receiver that has already been barreled as a rifle action in the assembly of a pistol, such an assembled pistol would constitute a "weapon made from a rifle" as defined in the NFA." [see attachment below....]
- For NFA and GCA purposes, does "receiver" include both the upper and lower halves of an AR15 assembly, or does it include only the lower half with the serial number?
- If #1 includes both the upper and lower halves in the definition, why is the lower the only one with the serial number, and the only one which requires an FFL to transfer, while I can mail order any assembled upper or upper parts I want without including an FFL in the transaction?
- If #1 does NOT include both halves in the definition, what is to stop me from having a pistol lower with one of those Sig (or other similar) braces, and multiple uppers with rifle, carbine, and pistol length barrels with appropriate optics?
- Regardless of whether #1 includes both halves in the definition, If I bought a stripped lower at a gunshow, and I assembled it into a rifle, shot it for a while, and then I later rebarreled the upper receiver to 7", removed the rifle/carbine buttstock and reconfigured it as a pistol, possibly with a Sig or other brand of brace, how on earth is BATFE going to know what the original use was, and whether it was modified or not subsequent to that? After all, a declaration of intended use was not a part of the original purchase transaction.
- Last question..... Hypothetical Scenario: I have an SKB double rifle case, inside of which are found two complete upper assemblies, and two complete lower assemblies, none of which is actually mated to the other:
- an assembled AR "pistol" lower, minus any fancy brace, with just the usual padded buffer tube, assembled using a stripped lower purchased from an FFL at a gunshow.
- an assembled AR rifle/carbine lower, with a 6 position collapsible buttstock, assembled using a stripped lower purchased FTF from a friend across town, which was originally purchased as a stripped lower from a local gunstore.
- an assembled AR upper with a 7" barrel and a Magpul AFG.
- an assembled AR upper with a 16 M4 profile barrel and a vertical foreward grip.
And just to reiterate, this is a hypothetical scenario. I do not own any ARs of barrel length less than 16".
