The Stoner 63 is a very good all-round weapon, with no particular weaknesses or strengths. As such, it is recommended for all soldiers without any recommended restrictions. While the M16 beats the Stoner in close range engagements and suppressive ability due to its high rate of fire and low recoil, the Stoner outclasses it in damage, range, reliability and ammunition capacity, both in the magazine and in reserve. This versatility makes it an effective choice for long patrols that may run into gunfights at various ranges.
Primarily used by US special forces, the Stoner 63 was developed in the beginnings of the 1960s. Only around 4000 were bought and utilized by the marines and Navy seals. The Stoner 63 was a variable weapon and came in multiple design configurations including light, and medium machine guns. However this weapon was not only used by the US military, other nations of the time such as West Germany also took interest in it as well; developing independent variable weapon modifications.
