Can you imagine though what today would be like had the Army adopted the Colt 703 during Vienam.
Just imagine where we would be if we had adopted a Piston AR-15 back in the day. Look how far the M4 has come because of all those who worked hard to make it the great weapon it is today.
I can just imagine the amazing rifle we would have today had we adopted this.
Just wanna add an edit: the 703 sure is a thing of beauty for its time
