Abstract
A hand guard is provided for a firearm, such as a rifle, and may be suitable for maintaining the alignment of the hand guard, and any accessories coupled thereto, relative to the rifle. The hand guard may be configured so that at least a portion of the hand guard can be removed from the firearm and then re-installed on the firearm without significant change in the orientation and position of the hand guard. The hand guard may also be suitable for coupling accessories such as lights, scopes, laser sights, and other firearm accessories to the firearm.
Claims18
A hand guard for a firearm comprising:
- an elongated housing comprising an upper part, a lower part and a locking structure, the upper and lower parts defining an interior space,
- one of the upper and lower parts having an interior portion with a first dimension that is sized to be received within the other of the upper and lower parts at an exterior portion having a second dimension larger than the first dimension,
- at least one of the upper and lower parts including a protrusion extending toward the interior portion while the other of the upper and lower parts defining a slot configured to accept the protrusion, the slot being generally L-shaped to receive the protrusion and permit the upper and lower portions to move in a plurality of directions relative to one another,
- the locking structure abutting the interior portion and cooperating with the protrusion and slot to limit movement of the upper and lower parts relative to one another when in an installed configuration,
- the locking structure being movable to an unlocked position thereby permitting the upper and lower parts to move relative to one another and disengage the protrusion from the slot.
