Benefits of technology

The present invention provides a handguard for a firearm that is secured to the barrel nut using internal wedges. The handguard can be easily attached to a standard AR-pattern firearm upper receiver. The handguard provides a barrel nut with a cylindrical outer surface and an annular groove. A handguard sleeve with an end opening and a channel is positioned over the barrel nut, and a pair of wedges are securely attached to the handguard sleeve using a wedge fastener. The wedge members are pulled together to secure the handguard in place. This invention provides a secure and adjustable handguard for firearms.

Problems solved by technology

However, unless mated with a proprietary design upper receiver, these typically involve the handguard having a longitudinal split that is drawn together to clamp it to the barrel nut.
Such clamping requires flexing a portion of the handguard material, which can distort or weaken it.

Abstract

A handguard for attachment to a standard AR-pattern firearm upper receiver. A barrel nut has a substantially cylindrical outer surface with an annular groove. A handguard sleeve has an end opening configured to slide over the outer surface of the barrel nut, a channel with a bottom guide surface, and a substantially transverse cross bore positioned to at least partially intersect the end opening to align with the annular groove when the handguard sleeve is positioned on the barrel nut. A pair of wedge members are sized to be received in the channel and connected by at least one wedge fastener configured to adjustably move the wedge members together. When the barrel nut is attached to an upper receiver, the handguard sleeve is attached to the upper receiver by sliding the end opening over the barrel nut and inserting a cross bolt fastener in the cross bore and a portion of the annular groove. The wedge members are pulled together by adjusting the wedge fastener, compressing them between the barrel nut and handguard sleeve.

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 62 / 487,010, filed Apr. 19, 2017, and incorporates the same herein by reference.TECHNICAL FIELD[0002]This invention relates to a firearm barrel handguard that attaches to an upper receiver by way of the barrel nut to allow a free-floating barrel.BACKGROUND[0003]Various structures and methods have been used to attach a handguard to a standard AR-pattern upper receiver, including some that secure the handguard to the barrel nut. However, unless mated with a proprietary design upper receiver, these typically involve the handguard having a longitudinal split that is drawn together to clamp it to the barrel nut. Such clamping requires flexing a portion of the handguard material, which can distort or weaken it.SUMMARY OF THE INVENTION[0004]The present invention provides a handguard attached to a barrel nut in which a pair of internal wedges are drawn together inside, but independent of, th...
