Anyone have a lead on 80% RPD receivers? I tried WiseLite and they've only got 100% and are running about 4 months out. I've got an email into DSA but haven't heard back yet, not expecting much different but we'll see.
Any other options out there (0%-100% or even bubba)? The milling looks to be simple enough on the chunks, any reason it couldn't be done with aluminum and cut some weight off this thing?
I've read, and read, and read but if you've got some favorite links for alternative builds on one of these I'm always up for reading some more.
