Honestly if you really don't want one don't bother getting one just to get famaliar (SP?) with the system. The Air Force if they choose to issue you one will teach you what you need to know about it.
If you shop around you can get other brands for 500 dollars less.

The upper dosen't make the weapon full auto, the lower does. The lower is the acutal "firearm" as far as the ATF is concerned. You can have hundreds of uppers shipped straight to your front door but the lower has to be shipped though an FLL holder. If you want a full auto lower you better start saving your pennies not even counting all the paperwork costs you are looking at enough money to buy some new cars to get a full auto lower.
