If you haven't already done so, write to your investment fund manager or whoever manages your investments for you making it clear that you will not fund arms related businesses or activities.
Dear Investment Fund Manager,
Since you manage investments on my behalf I should like your assurance that none of my money has been or will be invested in arms related enterprises and that it is your policy to avoid such investments.
Yours sincerely,
