I am pretty sure a passenger has taken his rifles onto multiple airplanes while on his way to Africa, or wherever. I'll be bringing some back to Nevada from back East in about a month. I have one of those two-gun cases that has six clip-locks on it. I think it's a Pelican. I have removed the clips on the ends; the four on the front remain. What I am asking in this post is, What kind of locks do I need in order to pass TSA muster regarding the locks? The case will go east empty, and return with two very precious family heirlooms in it. Thanks for the help.
