Honestly, it just kinda... happened. I made noise about picking it up for a while, and Mama Raptor gave the OK once I explained that no, I was not building a "Machine Gun," so I went ahead and picked up the lower. I kinda didn't tell Papa Raptor until after I bought it, but he turned out to be cool with it too.
And apologies for the thread derail, but I think Mama Raptor wants a gun. I wish I could say I was thrilled with this development, but the reason I think she wants a gun is because every time there been a terrorist attack, a BLM "protest," a thread of said "protest," or a particularly heinous crime has made the news over the last few months, I would say that I really needed to finish building my rifle, and then more often than not Mama Raptor would say that she was seriously considering buying a gun of her own. And she sounded serious.
