Drum magazine for loading paintballs and shaped projectiles into a magazine-fed firearm

A drum magazine for loading paintballs and shaped projectiles into a magazine-fed firearm comprises:

• a housing platform;
• a spiral feed track;
• a projectile feed assembly;
• a feed port;
• a modular feed adapter;
• a rotor protrusion;
• the projectile feed assembly comprises a clock spring, a spring rotor, and a radius-adjusting pusher arm;
• the radius-adjusting pusher arm comprises a linkage arm, a stabilizing arm, an extension arm, a forward nub, a reverse nub, and a single nub;
• the spiral feed track being integrated onto the housing platform;
• an inner end of the clock spring being positioned adjacent to a closed central end of the spiral feed track;
• an outer end of the clock spring being fixed to the housing platform;
• the spring rotor being axially connected to the inner end;
• the radius-adjusting pusher arm being slidably engaged into the spiral feed track;
• the feed port being in fluid communication with a peripheral end of the spiral feed track;
• the modular feed adapter being removably mounted to the housing platform, adjacent to the feed port;
• the rotor protrusion being peripherally connected to the spring rotor;
• the radius-adjusting pusher arm being pivotally and peripherally linked to the rotor protrusion;
• the linkage arm being pivotally and peripherally connected to the rotor protrusion;
• the stabilizing arm being pivotally and adjacently connected to the linkage arm, opposite to the rotor protrusion;
• the forward nub and the reverse nub being connected adjacent to the stabilizing arm;
• the forward nub and the reverse nub being positioned opposite to each other along the stabilizing arm;
• the extension arm being pivotally and adjacently connected to the stabilizing arm, opposite to the linkage arm;
• the single nub being connected adjacent to the extension arm, opposite to the stabilizing arm;
• the forward nub, the reverse nub, and the single nub being sequentially engaged into the spiral feed track;
• at least one buffer spring;
• and
• the at least one buffer spring being positioned in between the gear locking plate and the gear locking bracket.
