US12535289 - Firearm handguard attachment

A firearm is provided that comprises a barrel, a magazine tube below the barrel, and a handguard with first and second portions. A clamp between the handguard portions has a main body with deformable lugs and a fastener. The handguard's first portion features an arcuate surface for the barrel and a bore for the magazine tube. The lugs move inward and downward, securing the handguard. The clamp is positioned within a recess between the handguard portions. Fasteners are accessible through apertures in the handguard. The clamp contacts both the magazine tube and the barrel when tightened. The clamp includes a main body and deformable lugs, with a fastener to secure the handguard. The lugs are deformable, made of various materials, and designed to bend upon tightening. The method involves positioning and tightening the clamp to deform the lugs and secure the handguard.

Claim 1

1 . A firearm comprising: a barrel; a tube disposed below the barrel; a handguard configured to be mounted adjacent to the barrel and the tube, the handguard comprising a first portion and a second portion; a clamp positioned between the first portion and the second portion of the handguard, the clamp comprising: a main body positioned within a recess between the first portion and the second portion of the handguard; at least one pair of projecting deformable lugs extending from the main body, each lug having an upper end; and at least one fastener configured to tighten into the main body of the clamp, thereby causing the upper ends of the projecting deformable lugs to move toward each other; wherein the upper ends of the projecting deformable lugs are positioned between a concave inner surface of the handguard and the tube, and are configured to contact the tube when the at least one fastener is tightened. a barrel; a tube disposed below the barrel; a handguard configured to be mounted adjacent to the barrel and the tube, the handguard comprising a first portion and a second portion; a clamp positioned between the first portion and the second portion of the handguard, the clamp comprising: a main body positioned within a recess between the first portion and the second portion of the handguard; at least one pair of projecting deformable lugs extending from the main body, each lug having an upper end; and at least one fastener configured to tighten into the main body of the clamp, thereby causing the upper ends of the projecting deformable lugs to move toward each other; wherein the upper ends of the projecting deformable lugs are positioned between a concave inner surface of the handguard and the tube, and are configured to contact the tube when the at least one fastener is tightened. a main body positioned within a recess between the first portion and the second portion of the handguard; at least one pair of projecting deformable lugs extending from the main body, each lug having an upper end; and at least one fastener configured to tighten into the main body of the clamp, thereby causing the upper ends of the projecting deformable lugs to move toward each other; wherein the upper ends of the projecting deformable lugs are positioned between a concave inner surface of the handguard and the tube, and are configured to contact the tube when the at least one fastener is tightened.
