Did you really type that out loud? RRA mated to ANYTHING is just...well, and to add a DPMS lower? The OP asked for, well, more than you just offered? Not even sure if serious? Hopefully, purple was implied, and I’ve drank too much?Rock River Arms meets all of your criteria. My RRA NM service rifle upper arrived this morning and is already mated to a DPMS service rifle lower. It will be shot out to 600 yards.
