OK, I'll pile on the bandwagon here. *LOL*
Yes, you can "OC" but as has already been said, the weapon has to be empty & unloaded. IT WILL BE CHECKED! If it's a handgun, then it will have a zip tie run down the barrel and zipped. If you're slinging a long gun that utilizes a clip configuration, it will have a zip tie run through the chamber and down through the clip opening, thats how my Mini-14 sniper rifle was processed.
