Thanks all. I was able to pick up a different lower that I think will fit the scope of my project well. It's a post ban Colt Sporter Target lower that has a lot of wear and tear. Almost has that battlefield pick up look to it. Problem is that it has that damn block and the front takedown screw. The color is pretty much exactly what I was going for, though.
I'll start a new thread about it after it arrives, as I could use some suggestions and advice about it and the build that I'd like to accomplish with it.
Thanks again!!
