Airsoft Mike talks about the KIS Tool Organiser which he bought to have his gun wall... "Available from B&Q in the UK and other hardware stores worldwide. These were bought in person and not online, however, just copy and past "KIS Tools Organizer" into google to see if they are available in your country or available for you to buy online from overseas.

Wherever you purchase these, the retailer will tell you what screws and wall plugs are required, as they are sold separately."
