This has happened to me the past 3 times I've been pulled over (All for speeding). I let them know there's a gun in the car, where it is, and that I have my CCW. They relax then ask if I have any AR's (Due to the AR stickers on the back window) and we end up just talking about AR's and other guns for the next 5 minutes and I'm let off with a warning every time. Castle Rock cops are alright with me for now
