To enter, all you have to do is go to Amy's GoFundMe page, donate $25 or more, and forward your receipt email to ADillonBenefitRaffle AT gmail DOT com. Each $25 counts as one entry.
And even if you don't win the rifle, there are still other great prizes to be won, including signed books by such noted authors as Larry Correia, Sarah Hoyt, Michael Z. Williamson and Andrew Branca.
Donate to help a firearms instructor and fierce 2nd Amendment advocate! You might just win something really neat for your trouble!
