The Stoner63 is a "Classified" weapon, meaning it is unlocked by buying all other light machine guns before it can be bought itself, causing 6000 COD Points total to be spent on getting this weapon. It has a high rate of fire and low/moderate recoil, yet posesses a moderate magazine size like the HK21, therefore many users use Scavenger or Extended Mags. Also of note is that due to the Stoner63's 40 damage and very high rate of fire, it kills quicker than most other weapons in Black Ops (save for theASP or Python at max fire cap, and weapons with Dual Wield orRapid Fire attachments), especially at long range. These features, coupled with its decently low recoil makes it perfect for close-to-mid range combat, and performs very well if burst fired for long distances. It is worth noting that the Stoner63 is a one hit kill at all ranges in Hardcore game modes. When using Warlordwith the Stoner63, you are only permitted to use one sight and Extended Mags attachment, due to only being able to use one sight at a time.

The Stoner63 is a poor choice for short range, as in close quarters the weapon has only mediocre hipfire accuracy. However, this can be remedied with the Steady Aim perk. Unlike all other LMGs, the Stoner63 enters ADS in a quarter of a second, which is the same ADS speed as assault rifles. Also, in Create-A-Class 2.0, it is held by the character model as though it were an assault rifle rather than a light machine gun. Combined with its quick ADS time, rate of fire, and relatively fast reload without Sleight of Hand, it is very Assault Rifle-like, and it is commonly used like one, though the Extended Mags still double the gun's maximum cartridge ammo like it does for all other LMGs.
