Abstract

A rifle having a receiver alignment system includes an upper receiver and a lower receiver configured to engage with each other in an assembled configuration by aligning and pressing an exterior portion of the upper receiver into an interior portion of the lower receiver. A cavity is defined within the interior portion of the lower receiver configured to receive the upper receiver. A lug positioned on the upper receiver defines an alignment groove formed on a lower surface of the lug. A plunger pin is provided in a hole defined within the interior portion of the lower receiver. The plunger pin is configured to engage with the alignment groove and generate a spring-loaded tension when the upper receiver and the lower receiver are engaged in an assembled configuration.
