Abstract
A handguard assembly system for a firearm is disclosed. The system includes a handguard with an elongate perforated structure extending between a first end and a second end, where the handguard defines a handguard connector on the first end. An interfacing connector attaches to the handguard connector when the handguard is installed on the firearm. When installed on the firearm, the handguard extends over the barrel without directly contacting the barrel, and attaches to the firearm via the interfacing connector and an upper receiver connector on the firearm upper receiver.
Claims24
A handguard assembly system for a firearm, the system comprising:
- a firearm upper receiver having a distal end portion with an upper receiver connector;
- a handguard removably attachable to the firearm upper receiver, the handguard extending from a first end to a second end with a handguard connector on the first end and configured to engage the upper receiver connector when installed on the firearm upper receiver;
- and
- an interfacing connector constructed and arranged to attach to the handguard connector and secure the handguard connector to the firearm upper receiver.
The firearm handguard assembly system of claim 12, wherein the handguard is free floating over the barrel when installed on the firearm upper receiver.
A handguard assembly for attachment to a firearm, the handguard assembly comprising:
- an upper receiver with a barrel nut connector;
- a barrel secured to the upper receiver by threaded engagement between a barrel nut and the barrel nut connector;
- an interfacing connector disposed in contact with a top surface of the barrel nut;
- a handguard with an elongate perforated structure extending between a first end and a second end, the first end defining a handguard connector, wherein the handguard connector extends over the barrel nut connector, the barrel nut, and the interfacing connector when the handguard is installed on the upper receiver;
- and
- a plurality of fasteners configured to be installed between the handguard connector and the interfacing connector when the handguard is installed on the upper receiver;
- wherein, when installed on the firearm, the handguard extends over the barrel without directly contacting the barrel.
A method of attaching a handguard to a firearm, the method comprising:
- providing a firearm upper receiver comprising an upper receiver connector that includes a barrel nut connector and a barrel nut, a barrel with a gas block, and a tube or rod extending from the gas block to the firearm upper receiver;
- providing a handguard extending from a first end to a second end and defining a handguard connector on the first end;
- disposing an interfacing connector in contact with the upper receiver connector, the interfacing connector configured to attach to the handguard;
- sliding the handguard over the barrel and the gas block and onto the upper receiver connector in alignment with the interfacing connector;
- installing fasteners through the handguard connector and into the interfacing connector;
- and
- tightening the fasteners to draw the handguard connector against the upper receiver connector, thereby securing the handguard to the firearm without direct contact with the barrel or the gas block.
