Only charitable or nonprofit organizations operating a raffle may award firearms, air guns, or other mechanical devices which are capable of discharging dangerous projectiles, including but not limited to, BB or CO2 guns, rifles, shotguns, pistols or revolvers, or crossbows as a prize. The firearm must be authorized for sale in Washington state. If the prize awarded is restricted from transfer by state or federal law, the licensee must award the winner a certificate, redeemable by a licensed Washington state firearms dealer, for the prize offered. Alternatively, the winner shall be awarded a prize of equivalent value, such as a gift certificate, if the winner of the raffle is prohibited from owning or possessing firearms by other sections of the Revised Code of Washington (RCW).
