US12723839 - Barrel nut handguard system

A barrel nut handguard system can include a handguard with a sidewall defining a bridge opening extending to a handguard interior, a barrel nut defining a registration groove around a periphery of the barrel nut, and a connector bridge in the bridge opening so that a contact surface engages the first registration groove. A fastener extending between the connector bridge and handguard can be tightened so the barrel nut is clamped between the contact surface and the handguard interior. The contact surface can fit between walls of the registration groove and prevent fore to aft sliding of the handguard relative to the barrel nut. The barrel nut can include tool lands allowing tooled rotation of the barrel nut relative to a receiver of a firearm to secure a barrel to the receiver with the barrel nut, without requiring rotational indexing of the barrel nut relative to the receiver.

The patent describes a barrel nut handguard system designed to secure a handguard to a barrel nut of a firearm, featuring a connector bridge that engages a registration groove on the barrel nut to prevent sliding. The system allows for the barrel nut to be tightened without requiring rotational indexing, enhancing stability and ease of installation.

Claim 1

1 . An apparatus configured to secure a handguard to a barrel nut of a firearm, the apparatus comprising: a handguard including an elongated interior configured to fit over a barrel and a barrel nut of a firearm, the barrel including a barrel axis, the handguard including a first sidewall and an opposing second sidewall, with a first bridge slot defined by the first sidewall, the first bridge slot extending to the elongated interior and longitudinally along the handguard, the handguard including a horizontal midline bisecting the handguard into an upper portion and a lower portion located below the horizontal midline, the horizontal midline being parallel to a horizontal plane when the apparatus is secured to a firearm held in an upright, ready to shoot orientation; a first shoulder extending from the first sidewall and configured to receive a vertically extending first fastener that extends transversely to the horizontal midline from the upper portion of the handguard, downward past the horizontal midline, to the lower portion of the handguard; a barrel nut including a horizontal midline bisecting the barrel nut into an upper portion and a lower portion, the barrel nut including a periphery, the barrel nut defining a first registration groove around the periphery of the barrel nut, the barrel nut sized to be positioned in the handguard a interior adjacent the barrel; a first connector bridge disposed in the first bridge slot, the first connector bridge including a first ramped surface configured to engage the first registration groove in the lower portion of the barrel nut below the midline of the barrel nut, the first connector bridge oriented for engagement by the first fastener such that when the first fastener is tightened, the barrel nut is clamped between the first ramped surface and the elongated interior of the handguard a second connector bridge opposite the first connector bridge; and a second fastener distal from the first fastener, wherein the first connector bridge and the second connector bridge are in the lower portion, and wherein the first fastener and the second fastener extend in both the upper portion and the lower portion. a handguard including an elongated interior configured to fit over a barrel and a barrel nut of a firearm, the barrel including a barrel axis, the handguard including a first sidewall and an opposing second sidewall, with a first bridge slot defined by the first sidewall, the first bridge slot extending to the elongated interior and longitudinally along the handguard, the handguard including a horizontal midline bisecting the handguard into an upper portion and a lower portion located below the horizontal midline, the horizontal midline being parallel to a horizontal plane when the apparatus is secured to a firearm held in an upright, ready to shoot orientation; a first shoulder extending from the first sidewall and configured to receive a vertically extending first fastener that extends transversely to the horizontal midline from the upper portion of the handguard, downward past the horizontal midline, to the lower portion of the handguard; a barrel nut including a horizontal midline bisecting the barrel nut into an upper portion and a lower portion, the barrel nut including a periphery, the barrel nut defining a first registration groove around the periphery of the barrel nut, the barrel nut sized to be positioned in the handguard a interior adjacent the barrel; a first connector bridge disposed in the first bridge slot, the first connector bridge including a first ramped surface configured to engage the first registration groove in the lower portion of the barrel nut below the midline of the barrel nut, the first connector bridge oriented for engagement by the first fastener such that when the first fastener is tightened, the barrel nut is clamped between the first ramped surface and the elongated interior of the handguard a second connector bridge opposite the first connector bridge; and a second fastener distal from the first fastener, wherein the first connector bridge and the second connector bridge are in the lower portion, and wherein the first fastener and the second fastener extend in both the upper portion and the lower portion.
