How many ar-15 uppers per gun you have?

[ranger682]

I have one raw lower and one upper. I want to get several more uppers because of the options the RAW lower gives me. I really want a 50 cal but do not want to damage the lower. Thinking about just getting the 510 CA legal with a new lower??? Also want a flat top....Toys and boys!
