I have JUST - today - applied for a C&L; my local police chief has his copy and "COPY #1" is on its way to Atlanta....For me, I simply wish to be able to receive parts discounts for MY OWN PRIVATE USE...NOT for anyone else!! On that rare chance I come across an 1898 Mauser that grabs my interest....the C&L will be nice to have......
As long as you are good at keeping records/receipts, you should have no problems....DO remember, though....the mere fact that you possess a FFL - of ANY kind - means you are subject to "random" audits of your paperwork...at ANY TIME!!
My advice would be to err on the side of caution...DON'T make purchases for OTHERS...PERIOD!! What you buy....you KEEP!
Just my $.02 --- Good luck with your license!!!
