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.

The devices and methods described below provide for a forearm handguard for a rifle with multiple integrated power and communication channels that are accessible to any accessory through the different rail interface systems of the handguard. Any suitable rail interface systems may be used.

A handguard assembly for a firearm includes a body member having a first end, a second end, and an inner volume. The inner volume receives a barrel of the firearm. The first member is fixedly coupled with the body member at the first end. The handguard assembly also includes multiple elongated members that extend through the inner volume of the body member and fixedly couple with the first member at the first end of the body member. The elongated members extend through the second end of the body member and couple with a receiver of the firearm.

A handguard assembly for a firearm includes an outer member disposed forward of an upper receiver of the firearm where, a barrel nut disposed within the rear cavity, and at least one alignment member. The outer member includes a rear cavity and a threaded portion. The at least one alignment member contacts both the outer member and the upper receiver for alignment.

A firearm includes a muzzle device. The muzzle device includes a muzzle adapter and a muzzle attachment. The muzzle attachment suppresses noise and/or redirects gases and recoil. The firearm utilizes recoil operation to cycle such that the barrel reciprocates inside a handguard of the firearm during cycling. The muzzle adapter is attached to the handguard and receives the barrel therein. The muzzle attachment is secured to the muzzle adapter such that the muzzle of the barrel remains longitudinally in the muzzle adapter during discharge and cycling of the firearm.
