You should be okay if you JUST have a forum (like a classified section) which lets people buy/trade/sell firearms. Each seller (personal or business) is responsible for their own transaction and must ensure that the firearm is shipped to a vaild FFL, unless the transaction happens face-to-face (in person). This is actually part of the "gun show loophole" that Obama will probably try to close off. It's really no different than selling a shotgun in the local newspaper if it's face-to-face.

Only firearms are regulated in this manner. Ammunition can generally be shipped to persons that are 18 years of age or older. Magazines, and other accessories are not regulated like this.

Unfortunately, each state has different laws, so you will have to check with your state to see what your laws are.

My personal opinion (and experience) says that you should at least have a sort of disclaimer on your site, stating that you are not responsible for transactions, sellers are responsible for ensuring they are within all ATF regulations, etc.

You could also check forums like glocktalk.com and ar15.com and see what kind of disclaimers and actions they take to protect themselves, since they both have a buy/sell/trade forum for firearms and I have yet to hear of any negative action taken against them for any firearm related incidents.

Good luck.
