Seriously , read back what you just wrote down . You are obviously not comfortable lending him your things . Then don ' t . I personally always like to take nonairsofting friends to the field and let them use my guns . Hell , I often give a new player my pistol when he is out of ammo or something . But the rule with my group of airsofting friends is this a friend can use my gun . If a friend of mine uses my team mates gun I ' m responsible . If a friend of a friend uses my gun , my friend is responsible . If I pay for the bbs , then the people using my bbs pay for my drinks or food . Or someone else buys the bbs next time . When I get new bbs I often get a few bags , because I know my friends will use them . I don ' t mind . But if this would happen on a regular basis , I would suggest that my friend buys the next bag . Or that he can use my bbs if he pays my entrance fee or something . If your friend doesn ' t want his own gun , that is fine . Just tell him you ' re not comfortable with him using your high end gun . Or write down a loan contract or something , that can hold him accountable for any damage to the gun .
