What are good birthday gifts for my boyfriend?

My boyfriend and I have been dating for 7 months, and its his 17th birthday except I dont know what to get him. All he wants to do is spend the day with me, but I also want to get him something as well. I'll be spending the day at his house, which means his brothers and parents will be around too. My boyfriend hates video games...but he's really into guns and more 'hick' like stuff. I dont know if a gift card to maybe Gander Mountain would be very thoughtful, but thats what I was thinking of getting him. What do you think are good gift ideas?
