Tons of places sell surefire tail caps. Who sells the heads? I know you can get the Chinese stuff at Lighthound, and eBay. I just got into the 6P Lego thing pretty big, now I need a place for all my Malkoff's!
Check the CPFMP daily! There are heads, tailcaps, and any other assorted parts you may be looking for! But check frequently because they go fast and they go to the first in line. Happy hunting! :naughty:
