Please explain why this is so important to you to have an AR-15. We had guns in the house in leather locked bags and we shot them. I even pulled the trigger when my father sighted. He taught me to never pull a gun on any living being. I violated this teaching once, in Castroville, Texas, when I was 12 and practicing with my aunt's pistol. I shot at a spider on the back of the garage.
Explain yourself and why you would need an assault weapon.
When a firearm is needed, the body's adrenaline is pumping and even trained police officers, actually "miss" half the time when shooting. A semi-automatic rifle actually makes hitting the target easier, even if your adrenaline is going and if there is a home-invasion, or armed robbers in your home and a serious threat to your life.
Also, a knife, sword, hammer, screwdriver, bat, or even your fists are literally, "assault weapons," when you are "assaulting" someone and semi-automatic rifles with a ten, twenty, or thirty round magazine, are separately being called, "assault weapons" to simply make you think they are "more scary" than other things used in a crime.
Separately, read the Second Amendment......AND......the Federalist Papers by our founding fathers.
The right to bear arms wasn't to ensure hunting...although even nations with strict gun laws, allow for their citizens to have hunting weapons. The founding fathers saw where civilian groups gathered together, forming guerilla militias, were critical to winning the war against England and wanted to ensure that should any future tyrannical government, whether foreign...or...domestic attempt to conquer this nation and take away the rights under our Constitution, civilian militias could form and assist in defending the individual states.
It has been said that Emperor Hirohito considered invading the United States with ground troops, but was dissuaded by his generals, as, "there would be a gun under every blade of grass." Whether that is a factual quote, I don't know. However, not long ago, our chief adversary, China, has said that they perceive American citizens owning firearms as a "problem." That should be a hint to definitely...."keep the firearms, including AR-15 style rifles," in the hands of "LAW-ABIDING Citizens." For the LITERALLY TENS OF MILLIONS of "law-abiding" citizens are literally that....law-abiding and NOT committing any crimes with their firearms and that includes the millions of AR-15 style semi-automatic rifles with large capacity magazines in their hands.
