I have them NRA checks, the side-tear ones with the Constitution and the musket in the background. I even shelled out the extra 2 bucks to put my own line on them. I put in "The right to keep and bear allows us to exist at all." Never gotten a complaint from it. Hell, I have a couple of credit cards from citibank and use the checks to pay them off. One I don't like about the NRA check program is that you have to purchase 2 boxes.

I just have my regular checks (from checks unlimited) customized with a patrotic symbol and a pro-gun message.
