Abstract: An apparatus for extending the magazine well of a firearm has extender body dimensioned to receive a firearm magazine and an expandable securing mechanism coupled to the extender body and selectively expandable against the internal cavity adjacent the magazine well on most firearms. Movement of a driving element in the expandable securing mechanism causes an expandable member thereof to transition from a first unexpanded configuration to a second expanded configuration for frictionally engaging interior surfaces of the internal cavity, and vice versa.

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

Abstract: 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.

Abstract: A modular system for mounting firearm accessories and a method for attaching a firearm accessory to a firearm are provided. In one example, the modular system includes a first mounting member capable of receiving a firearm accessory, the first mounting member having a channel and a stopping means in the channel, a second mounting member capable of combining with the first mounting member, the second mounting member having a cavity, and a joining mechanism disposed in the channel of first mounting member and the cavity of the second mounting member for releasably combining the first mounting member with the second mounting member. The joining mechanism is rotatable about an axis parallel to the channel and perpendicular to a longitudinal direction of a firearm.

Abstract: 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.

Abstract: 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.
