It looks like this: The ATF had previously sent out a letter stating that the Sig brace was legal to shoulder due to the fact that you were not redesigning the weapon in any way. Here is what that looks like: Not it seems the ATF has reversed its decision and decided that the Sig brace, if shouldered, now falls under the scope of the NFA (National Firearms Act) and shouldering the weapon somehow "redesigns" the weapon. To me, this sets a dangerous precedent. Government bureaucrats shouldn't be arbitrarily deciding how you can even hold your own property! My personal opinion, the NFA needs to be abolished. A private citizen has the right to alter, redesign, or change his/her own property in any way they see fit so long as they harm no one else, regardless of any state edict. Thoughts?
