Like I said, my suggestion to him was to go out and buy a second lower, but he's too stubborn. Talked about it with him again last night and he says he's going forward with the one he has (Spike's Punisher). The way he tells it, he has just enough money for the tax stamp and the upper, and wants to save his money for an EOTech. He's not interested in adding the cost of another custom lower to the mix. I told him that when I get around to making my own SBR, it's going to put his to shame.
