I did a google search seeing if anyone wrote to the tech branch yet.
After reading this and a few others I encourage everyone... dont.
Either way pistol grip or magpul angled grip NEITHER can be an AOW. Read the actual USC it states clearly that an AOW can not have a rifled bore. The tech branch can publish opinions until they are blue in the face that is purly wrong and it says it right there in the code.
That's the sneaky little catch they get you on. The USC exempts pistols and revolvers that have rifled bores from being AOWs, but it does not exempt all firearms with rifled bores. This is laid out in the last sentence of the paragraph that defines AOWs in the USC.
The ATF's argument is that when you add a second grip (of any type) the weapon is no longer a pistol. If it is not a pistol then it can be an AOW, whether or not it has a rifled bore.
Personally I think this is a lousy argument that a decent lawyer should be able to take apart based on other clear language that can be found in 26 USC as well. However, no one has done so yet and I'm definitely not willing to test it myself.
The really confusing part is that the term "pistol" is not defined in the USC, it is defined in the Code of Federal Regulations. The CFR can be interpreted and modified by administrative agencies (like the BATF) without any congressional action. As I'm sure most people reading this know, the CFR defines pistols as being designed to be fired with one hand.
It gets even more convoluted when you start to consider what the BATF thinks the terms "designed", "originally", and "made" mean.
