I might piss some of ya'll off, but I don't see any reason a civilian would have a need for that.
I don't know why anyone needs a rifle that will kill a deer over 150 yards. I have never shot that farther than that. I don't know why anyone needs over a 6x scope. I don't know why anyone needs hollow point ammo. I don't know why anyone needs more than 20 rounds of ammo. I don't know why anyone needs more than 2 guns in their home. I don't know why people even need hunting rifles, you can purchase meat at the store cheaper than hunting in most cases. I don't know why............
You are running down a very, very slippery slope. That is why very smart people wrote the constitution, and didn't limit the 2nd amendment.
