This is going to be easy and hard - way too much room to wander. A price range would really help. Anything that you specifically DO NOT want it to be? Some off the top of my head tactical shooter suggestions:
Optics are nice (and not always too expensive), like a laser rangefinder, a spotting scope; a fixed power red-dot scope for rifle or shotgun. If your guy is a reloader, that opens a whole other area of possible giving.
