FIELD OF THE INVENTION

The present invention relates generally to firearm accessory mount. More specifically, the present invention is firearm accessory mount that facilitates the interchangeability of barrels on a firearm while maximizing the mountable surfaces on a firearm. The present invention provides a mount that is lightweight and releases the heat escaping the barrels mounted onto the firearm.

BACKGROUND OF THE INVENTION

Most modern firearms are equipped with standardized accessory mounting rails that allow the attachment of a variety of firearm accessories. Such firearms include optics and laser aiming devices, both of which enhance the capabilities and precision of a shooter. Typical mounting rails are oriented parallel to the barrel. More specifically, the mounting rails are typically located along the top of receivers or along various locations around the barrel. Firearms such as the M4 carbine may have a mounting rail system that surrounds the entirety of the barrel. This type of mounting rail system is compatible for the M4 as the firearm doesn't require quick barrel changes.

However, on firearms such as the M240 machine gun, barrels often overheat from repetitive firing, and in combat, the barrels need to be changed out quickly and efficiently in order to resume firing. Mounting rail systems that completely envelop the barrel, such as that of the M4 carbine, do not allow for a quick replacement of barrels. Therefore, typical mounting rail systems have rails along the sides of the barrel and beneath the barrel. The area above the barrel is left unimpeded in order to perform quick barrel changes. This arrangement however is at the expense of a rail above the barrel, limiting the mounting options for firearm accessories. The present invention provides a mounting rail system that provides mountable surface above the barrel while allowing quick and efficient barrel changes. The present invention also provides lightweight firearm accessory mount that accommodates the heating of barrels.

As shown in FIG. 2, the present invention comprises a left tactical rail 1, a right tactical rail 2, a gas-cylinder clamp, an upper tactical rail 7, and an elongated fixture 8 with a transversal arc-shaped cross section. The left tactical rail 1 allows firearm accessories to attach onto the left side of the gas cylinder of a firearm. The right tactical rail 2 allows firearm accessories to attach onto the right side of the gas cylinder of the firearm. The gas-cylinder clamp mounts the present invention onto the gas cylinder of the firearm. Furthermore, the gas-cylinder clamp comprises a first elongated jaw body 4, a second elongated jaw body 5, and a cylinder-receiving hole 6, as seen in FIG. 1. The first elongated jaw body 4 positions the left tactical rail 1 and the right tactical rail 2 onto the gas cylinder of the firearm. The second elongated jaw body 5 surrounds the remainder of the gas cylinder and secures the first elongated jaw body 4 onto the gas cylinder of the firearm. The cylinder-receiving hole 6 allows the insertion of the gas cylinder within the gas-cylinder clamp. The upper tactical rail 7 allows firearm accessories to attach onto the present invention, above a barrel that is attached to the firearm. The elongated fixture 8 braces the corresponding barrel. More specifically, the arc-shaped cross section allows the interchangeability of the corresponding barrel without altering the position of the firearm or the present invention about the firearm.

The overall arrangement of the aforementioned components allows the present invention to be attached onto the gas cylinder of a firearm and provide mountable surfaces for a variety of firearm accessories. The present is shown mounted onto a gas cylinder in FIG. 2. In order for the present invention to be attached onto a variety of gas cylinders, the first elongated jaw body 4 is detachably attached along the second elongated jaw body 5, as seen in FIG. 7. Preferably, a plurality of second fasteners 16 secures the first elongated jaw body 4 and the second elongated jaw body 5 to each other and provides a clamping force around the gas cylinder. The plurality of second fasteners 16 are shown separated from the first elongated jaw body 4 and the second elongated jaw body 5 in FIG. 7. More specifically, the first elongated jaw body 4 is connected along the second elongated jaw body 5 by the plurality of second fasteners 16. The cylinder- receiving hole 6 is delineated in between the first elongated jaw body 4 and the second elongated jaw body 5 so the gas cylinder is secured within the gas-cylinder clamp 3. As a variety of firearm accessories are meant to be mounted onto the left side and the right side of the gas cylinder, the left tactical rail 1 and the right tactical rail 2 are connected along the first elongated jaw body 4. More specifically, the left tactical rail 1 and the right tactical rail 2 are positioned opposite to each other about the cylinder-receiving hole 6. In order to guide the corresponding barrel onto the gas cylinder, the elongated fixture 8 is detachably attached along the first elongated jaw body 4, opposite to the second elongated jaw, also illustrated in FIG. 7. Moreover, the elongated fixture 8 is replaceable with a variety of other firearm accessories such as heat shields. In order for the barrel to be quickly and easily replaced, a barrel receiving hole is laterally delineated by the arc-shaped fixture, as seen in FIG. 4 and FIG. 5. The barrel-receiving hole 9 accommodates the path of the corresponding barrel onto and off of the firearm. The preferred embodiment of the elongated fixture 8 further comprises a first straight edge 28 and a second straight edge 29, as illustrated in FIG. 6. The first straight edge 28 and the second straight edge 29 both accommodate the structure of the corresponding barrel and the firearm, as well as the movement of the corresponding barrel into and out of the barrel-receiving hole 9. The first straight end 28 and the second straight end 29 are positioned opposite to each other along the elongated fixture 8. More specifically, the second straight end 29 is positioned perpendicular to the barrel-receiving hole 9 and the first straight end 28 is slanted towards the second straight end 29.

In order to and attach firearm accessories above the corresponding barrel, the upper tactical rail 7 is connected along the elongated fixture 8. More specifically, the upper tactical rail 7 and the first elongated jaw are positioned opposite to each other about the barrel-receiving hole 9, allowing firearm accessories to be mounted above the corresponding barrel. In the preferred embodiment of the present invention, a lower tactical rail 10 accommodates the mounting of firearm accessories beneath the gas cylinder of the firearm. The lower tactical rail 10 is connected along the second elongated jaw body 5, opposite the first elongated jaw body 4. This configuration allows a vertical grip to connect to the gas cylinder of the firearm, among a variety of other firearm accessories.

In order to position the elongated fixture 8 onto the first elongated jaw, the preferred embodiment of the present invention comprises a first prong 11, a second prong 12, a first slot 13, and a second slot 14, illustrated in FIG. 7. The first slot 13 and the second slot 14 receive the first prong 11 and the second prong 12, respectively, as seen in FIG. 1 and FIG. 2. More specifically, the first slot 13 laterally traverses into the first elongated jaw body 4, opposite to the cylinder-receiving hole 6, and the second slot 14 laterally traverses into the first elongated jaw body 4, opposite to the cylinder-receiving hole 6. This configuration allows the elongated fixture 8 to be mounted above the gas cylinder. The first slot 13 and the second slot 14 are positioned offset from each other along the first elongated jaw body 4, in order to balance the elongated feature and any attached firearm accessories on the upper tactical rail 7 about the first elongated jaw body

4. The first prong 11 and the second prong 12 are connected along the elongated fixture 8, opposite the upper tactical rail 7, as to offset the upper tactical rail 7 and define the barrel-receiving hole 9. More specifically, the first prong 11 is engaged into the first slot 13, and the second prong 12 is engaged into the second slot 14, thereby allowing the attachment and removal of the elongated fixture 8 onto the first elongated jaw body 4. Preferably, a plurality of first fasteners 15 further secures the elongated fixture 8 to the first elongated jaw body 4, as seen in FIG. 7. The elongated fixture 8 is connected along the first elongated jaw body 4 by the plurality of first fasteners 15. The plurality of fasteners is a plurality of screws that traverses along the first elongated jaw body 4 and through the elongated fixture 8.

As the elongated fixture 8 surrounds the corresponding barrel of the firearm, the increasing temperature of the barrel must be released in order to prevent overheating of the barrel. A third set of ventilation holes 17 allows the heat to escape from the barrel, preserving the integrity of the barrel as well as that of both the elongated fixture 8 and the first elongated jaw body 4. The third set of ventilation holes 17 laterally transverse into the elongated fixture 8 and is distributed along the elongated fixture 8, illustrated in FIG. 3 and FIG. 6. This configuration maximizes the amount of heat that escapes from the barrel.

In order to prevent the present invention from spinning, the preferred embodiment of the present invention comprises a rotation-inhibiting feature 18, shown in FIG. 3. The rotation-inhibiting feature 18 comprises a first tab 19 and a second tab 21, as seen in FIG.

The first tab 19 and the second tab 21 are positioned parallel to each other and are tangentially positioned to the cylinder-receiving hole 6, thereby surrounding the gas cylinder. Moreover, the first tab 19 and the second tab 21 are positioned opposite to each other about the cylinder-receiving hole 6. This configuration secures the orientation of the first elongated jaw body 4 about the cylinder receiving hole.

As shown in FIG. 5, the first tab 19 and the second tab 21 preferably each comprise a faceted surface 20 which accommodates the structure of the gas cylinder, specifically, the faceted surface 20s of the gas cylinder. The first tab 19 and the second tab 21 ensures the orientation of the first elongated jaw body 4 about the gas cylinder. The faceted surface 20 of the first tab 19 and the faceted surface 20 of the second tab 21 are positioned parallel to each other. More specifically, the faceted surface 20 of the first tab 19 and the faceted surface 20 of the second tab 21 are oriented towards each other. An offsetting feature 22 prevents any linear movement of the present invention about the gas cylinder. The offsetting feature 22 and the rotation-inhibiting feature 18 are positioned opposite to each other along the first elongated jaw body 4, shown in FIG. 6. This configuration accommodates the structure of the gas cylinder and positions of the rotation-inhibiting feature 18 onto the gas cylinder such that the faceted surfaces of both the first tab 19 and the second tab 21 effectively press against the faceted surfaces of the gas cylinder.

In order to prevent the present invention from sliding about the gas cylinder, the preferred embodiment of the present invention comprises an offsetting feature 22, shown in FIG. 1 and FIG. 2. The offsetting feature 22 comprises a third tab 23 and a fourth tab 25. The third tab 23 and the fourth tab 25 are terminally connected to the second elongated jaw body 5 and are laterally positioned about the cylinder-receiving hole 6 as to accommodate the cylindrical structure of the gas cylinder. More specifically, the third tab 23 and the fourth tab 25 each comprises a concave surface 24, as seen in FIG. 4. The concave surface 24 encloses around the gas cylinder. In order to grasp the gas cylinder, the concave surface 24 of the third tab 23 and the concave surface 24 of the fourth tab 25 are concentrically positioned to the cylinder-receiving hole 6. A rotation-inhibiting feature 18 prevents the present invention from spinning about the gas cylinder. As seen in FIG. 6, the offsetting feature 22 and the rotation-inhibiting feature 18 are positioned opposite to each other along the second elongated jaw body 5 in order to accommodate the structure of the gas cylinder and to effectively position of the offsetting feature 22 onto the first elongated jaw body 4. The preferred embodiment of the present invention further comprises a first set of ventilation holes 26 and a second set of ventilation holes 27, seen in FIG. 7. The first set of ventilation holes 26 allows heat to escape from the area of the gas cylinder adjacent the first elongated jaw body 4. Similarly, the second set of ventilation holes 27 allows heat to escape form the area of the gas cylinder adjacent the second elongated jaw body 5. More specifically, the first set of ventilation holes 26 laterally traverses through and is distributed along the first elongated jaw body 4. The second set of ventilation holes 27 laterally traverses through and is distributed along the second elongated jaw body 5.
