Well I think the Stinger missiles would be a bitch to get hold of unfortunately. And if caught in your possession would likely get you time in jail. BUTTTTTTTTT an AR-10 like you have or other high powered rifle with some heavy duty ammo would likely blow it out of the sky just the same I would think. Might take a few rounds in the right spot but that would be the fun part. That would make for an exciting hunting weekend too. I have a video from Dillon Precision when I bought my re loader called Fire Storm in the Sky with just such a situation. A bunch of guys and gals are shooting at this drone that is flying around and being maneuvered up and down and around by someone. Man that would be a blast to experience. Everyone is just blasting away at this drone full blast. Hey perhaps a new "Hunting Sport" could be started. You could put notches in your rifle stock for every drone you shoot down. Could even be contests with prizes etc. I think there is money in this,lol....................... And the government is supplying the drones. Doesn't get any better than that. Just like welfare for shooters. Hey they deserve a piece of the pie too.
