Now, why does this matter? Because the National Rifle Association (NRA) estimates about eight million AR-15s, and its variations are in circulation. That’s why we decided to take on this beautiful big boys gun and dispel the rumors, and its terrible rap amongst non-gun enthusiasts. Due to the popularity of this so-called “little black rifle,” we agree that the “AR” should stand for “America’s Rifle.” It’s carried by at least 8 million American across the United States which of course includes the proud citizens of OKC.
