Yes, I jumped through all the hoops. Waited less than 5.5 months on a paper Form 4 though so that was nice. I have two SBR uppers for my SBR lower. Just can't have any extra lowers lying around. This is the standard configuration...
From what I understand, it's legal to have rifle lowers and as many pistol/SBR uppers as you want, as long as at least one of them is SBR'd. I'm not a lawyer or Eric Holder, so it's all just from my understanding of what I've read on the the interwebz.
Welcome to the Barbie For Men club! With it comes a range of gadgets and accessories, far as the eye can see, to dress up your new lady with! (some of which will be thought of as more "flashy" or "slimming" than others)
Though, as the old saying goes "less is more", as the basic configuration and profile of your AR as it is will always be hard to beat. If you can master the lost art of contentment and work on proficiency with your piece as she is, then our hats will be off to you!
