Thanks for the replies! I bought 2 lowers a couple years ago intending to build my own. They sat there for quite a while, I lost interest and sold them both, one to a buddy of mine. I didn't realize at the time that I was expected to build the damn thing for him too!! So, I've been slooooowly looking for some parts for it and happened to see this one. I think I can put off the parts search long enough for him to get tired of waiting for me to get it done. I figure getting a bbl should get me through this year at least LOL.
