Here's the results for day twelve:

Chris M. - "RTR" at CO-AR15.com won the Daniel Defense Omega Carbine Rail System.
Brad J. - "Squeky" at gun-deals.com won the Larue Tactical Rifle Accessory kit.

Thanks for playing, I appreciate all the entries and I wish I had more to give away. I know a lot of people entered every day and didn't get anything, but hopefully we're going to have another version this summer, so stay tuned for more fun and thanks again!
