Start or Keep calling your senators and congessmen and let them know that you will vote them out if they support AWB or Universal Background checks(UBC) or any other form of gun control over and above what we have now.
If the government manages to pass UBC then YOU won't have any recourse to hide your guns when the government comes for them to confiscate them. Because it will force private sales to go through the FFL process and if you don't comply it will be a felony with 10 yrs jail associated sentences!
Gun shows do FFL , vendors do FFL so any purchases that you made through this process has already been added to the govs electronic database(which is against law!). Keep private sales PRIVATE to keep ur guns!
