Have you heard the government is considering banning sales of certain ammunition fired in the AR-15 rifle, and wondered what was going on? Non-enthusiasts should know the AR-15 rifle is the civilian version of the M-16 infantry weapon, and unlike the military version cannot fire in machine gun mode.
John Hinderaker of Power Line blog has a good, short tutorial on the issues involved. I learned something from what he wrote. Namely, that just about any rifle bullet will penetrate a police armored vest. If that is so, I wonder why our infantry who mostly operate against people armed with rifles wear them?
