Way back in December I ordered two AR lowers from Brownell's; they came in this week. I'm debating what to do with them. My original plan was to build one into an AR pistol and build the second into a "normal" AR (16" barrel, adjustable stock, etc...) to go along with my current two AR's (a 5.56 SBR and a .22 dedicated-upper AR) Now that I think about it more, I'm not sure there's any point to building an AR pistol when I already have an AR SBR. It's kind of the same thing, isn't it? What do you guys think?
