We ran across this product and it looks like it might be a good option for those that need to keep your AR-style weapon safe. The AR Magvault is designed to fit into the magwell and lock into place with a key. This will prevent any magazines from being inserted in the magwell or rounds being chambered. The AR Magvault is bright orange so that you know that it is in place. The manufacturer, Gun Vault claims that it will fit virtually any AR-style gun but we suggest you contact them if you are running other than a mil-spec weapon.
