Change from M1 Grand to M4A1

This post is about how the change of technology and how we went form shooting a M1 Grand rifle to a M4A1 light assault rifle. The M1 Grand was the stander rifle for the U.S Military during WW2 it was the first semi fired rifle used during that time No other country had a semi fast rifle there used pretty much blot action rifles. The M1 shot a 30-06 caliber round very powerful and could shoot up to 1000 yards if shot correctly. Now we started making changes to the rifle during the Vietnam war it was the M16 witch shot rapid fire 223 or 556 NATO round which is smaller but can shoot further and pretty much better rate of fire and very light wight. From there we Made the M4A1 which shoots the same as the M16 but even more light wight and very tactical we made this during Afghanistan war.
