General google requirements on weapons:
What's the policy?
Google ads are not permitted to appear on sites that sell, facilitate or advocate the sales of weapons and weapon accessories. This includes but is not limited to the sales of ammunition, gun parts, hardware, pistols, rifles, BB guns, sporting guns, air guns, blow guns, and stun guns. This policy also prohibits the placement of ads on sites which sell explosives, including fireworks.
Of course every contract CAN be modified ... and google generally has it so that the contract cannot be distributed ..
