We're guessing Minnesota Rep. Chip Cravaack (R) is a big supporter of the Second Amendment.
"This weekend," writes Cravaack, "I'll be using my AR15 223 5.56 UTG rail, generic stock & grip. NcSTAR scope. Might be borrowing my buddy's AR10 308."
The best part of the picture is it looks as if Cravaack's rifle is pointing at his decorative "Friends" tchotchke.
