Mark Grimsley has written a great article about the basics of the AR-15 platform. This is a good source of information for the beginner to familiarize oneself with America’s most popular firearm.
Also to combat the empty headed ramblings of the elitist anti-gun numbnuts when they spew their misinformation & outright lies about the weapon.
Friends who love President Trump, America, Freedom of Speech, The 2nd Amendment, and EACH OTHER!!
