Has there ever been a CLAIM, let alone proof, that a 7n6 was fired out if a handgun at ANYBODY?
I'm aware of a 5.45 upper for an ar but due to price I'm willing to bet no gangstas are going to fork out $500 for the upper, plus $200 for a lower. At least not when they can buy 2 glocks for that... Or 5 hipoints!
