A quick release, free floating, multi-piece forward hand guard assembly for a rifle includes an inner barrel nut adapted to be affixed to a front of the rifle receiver and an outer barrel nut telescopically received over the inner barrel nut and longitudinally secured thereto. The outer barrel nut is non-rotatable with respect to the inner barrel nut. A first hand guard element is engaged with and extends forwardly from the outer barrel nut in a laterally stable cantilevered fashion, and a second hand guard element is matingly engaged with the first hand guard element for surrounding the rifle's barrel and is free floating therefrom. The second hand guard element is attached to the first hand guard element with at least one quick release fastener.

Quick release hand guard assembly for a rifle

Hand guards for firearms and related methods are provided. In one example, a hand guard includes an elongated housing. The elongated housing comprises a lumen configured to substantially surround an intermediate portion of a barrel of a firearm, a lateral side wall, and a pair of inclined side walls respectively disposed on opposite sides of and inclined relative to the lateral side wall. Each of the inclined side walls comprises an elongated slot, wherein the elongated slots of the inclined side walls define a pair of angulated faces of a rail adapted to receive an accessory to be mounted thereon. For example, the rail may be a reduced-height Picatinny rail provided by the lateral side wall of the housing.

Accessory mounting hand guard for firearm

A clamping mechanism for attaching a handguard to a firearm includes a barrel nut having radially outwardly directed tines, a tubular body having a plurality of longitudinal grooves separated by lands forming an inner surface of the tubular body, and a pair of circumferentially extending grooves traversing the lands, formed forward from a rearward end of the tubular body. A clamp element is carried by the tubular body and includes a body with a beveled end and a heel extending substantially perpendicularly from an opposing end of the body. The clamp element is adjustably positioned within the tubular body with the heel extending radially outwardly and received in the second groove and the beveled end engages the barrel nut.

Firearm handguard system

A firearm handguard assembly system is disclosed. The system comprises a handguard including at least four apertures, a barrel nut having a first threaded end and a second smooth end, the threaded end coupled to the handguard, and an index block including at least four apertures, the index block coupled to the handguard by at least four screws, each screw having a head and a tip, the tip threaded through: one of the at least four apertures on the index block, and one of the at least four apertures on the handguard.

Firearm handguard assembly

The present invention describes a firearm hand guard assembly attachable to a firearm upper receiver and surrounding the firearm barrel distally along the longitudinal axis without touching the barrel. The hand guard assembly is comprised of an upper component and a lower component such that when the upper component and lower component are attached to one another with a firearm disposed therein, the sole contact between the firearm and the hand guard assembly is the contact between the firearm barrel nut and the inner surfaces of the proximal end of the hand guard assembly.

A modular fore-end rail assembly for mounting onto a firearm includes a hand guard and a bushing element that combines with an end portion of the hand guard to encircle the standard barrel nut, thereby supporting the entire assembly without requiring modification to the standard barrel nut. The thermal transfer characteristics of the material from which the bushing element is manufactured may be selected to either increase or decrease the rate at which heat is transferred from the barrel nut to the hand guard allowing for rapid changes of bushing elements and, therefore, rapid and selective changes in the heating rate of the hand guard.

Modular fore-end rail/hand guard assembly system for firearms with selectable heat dissipation characteristics

A modular system (100) for mounting firearm accessories and a method for attaching a firearm accessory to a firearm are provided. In embodiment, the modular system (100) includes a first mounting member (110) capable of receiving a firearm accessory, and a second mounting member (120) capable of combining with the first mounting member (110). A joining mechanism (130), rotatable about an axis perpendicular to a longitudinal direction of the firearm, releasably joins the first mounting member (110) with the second mounting member (120). In another embodiment, the modular system (10) further includes an adjustment mechanism (170) for adjusting engagement tightness of the mounting members (110,12) with a mounting site (200) to ensure more secure joining thereof.

Modular system for mounting firearm accessories and method for attaching firearm accessory to firearm

A modular system for mounting firearm accessories includes a first accessory mounting member attachable directly to the firearm accessory and a second firearm mounting member to which first accessory mounting member may be removably joined. The first and second mounting members are frictionally engaged with interlocking barb(s) and a retention pin. One or more of barbs project from the first mounting member, each having a substantially rounded tip and a tapered or gradually decreasing diameter shaft, and are received within a complementary shaped aperture on the second mounting member. A retention pin disposed within a transverse channel in the second mounting member, and having corresponding area(s) of reduced diameter along the shaft thereof, is removably secured against the barb(s) at a right angle thereto when the barbs are received within the second mounting member, frictionally securing the two members together. The first mounting member may have various shapes and configurations, as well as attachment mechanisms, for securing a firearm accessory directly thereto prior to its engagement with the second mounting member on the firearm.
