Lubrication device integrated into a firearm upper receiver

A lubrication device for dispensing lubricant, the lubrication device comprising:

• a lubricant container including a dispensing nozzle and an actuator head;
• an insert configured to be received within an aperture opening into an interior of a firearm receiver, the insert defining a bore configured to receive at least a portion of the lubricant container, a nozzle aperture into which the dispensing nozzle extends, and a shoulder;
• a plunger coupled to a rearward end of the insert and configured to engage a rearward end of the lubricant container;
• and
• a spring positioned within the bore and configured to bias the lubricant container rearwardly within the bore;
• wherein upon depression of the plunger, the lubricant container is driven forward within the bore until the actuator head engages the shoulder, and continued forward movement of the lubricant container relative to the actuator head causes lubricant to be dispensed through the dispensing nozzle and into the interior of the firearm receiver.

A firearm receiver assembly comprising:

• a receiver defining an interior;
• a forward assist housing disposed on a sidewall of the receiver, the forward assist housing defining an aperture opening into the interior of the receiver;
• and
• a lubrication device supported by the forward assist housing, the lubrication device comprising an insert positioned within the aperture and being configured, when actuated, to dispense lubricant into the interior of the receiver.
