Gearhead - For this airsofter, guns and gear are the main reason to be involved in airsoft. The enjoyment comes from constantly upgrading, modifying, and customizing their guns and gear. If they are not up to their elbows in gear grease, then they are having a bad day. A subcategory of this particular airsofter would best be described as a "Tinkerer". The main difference is that a Tinkerer is more apt to invent a new airsoft gadget or do some strange custom modification to an existing airsoft weapon, regardless of its practical usefullness. The Gearhead is just concerned with making the most reliable, highest fps, highest rps, most realistic replica possible.
