Many police supply stores will sell racks intended to mount AR-15s in cruisers. With a little ingenuity these can be made to work in the home. There's also a product called the Life Jacket which completely encloses the AR-15's reciever and can be bolted down. It uses two key locks which is a little slow to access, however.
Whatever option you go with, it should be combined with a healthy does of education. It's important to both take the mystery out of firearms and set clear rules surrounding them.
