Abstract: An improved mounting assembly is provided that is configured to be releasably attached to a standard dovetail rail profile, wherein the initial clamping tension of the clamping actuator is adjustable. The mounting assembly generally includes a main body having a lower portion that is configured to engage a standard dovetail and an upper portion accessory receiving formation. The lower portion of the mounting assembly has a first engagement member extending downwardly along one side thereof for engaging one side of the dovetail rail and a clamping assembly to engage the opposing side of the dovetail rail. At least one spring and a retention nut are provided as part of the clamping assembly such that retention nut controls the preset spring tension thereby controlling the clamping force applied by the clamping assembly.

Abstract: A mounting assembly for mounting accessories to a dovetail rail on a firearm is provided. The mounting assembly includes a main body having a lower portion with a first engagement member extending downwardly along one side thereof and a clamping assembly installed into the main body opposite the engagement member such that the clamping assembly can be engaged and disengaged with the dovetail rail to hold the mounting assembly on the dovetail rail. In addition, a buffer pad is provided between the clamping assembly and the interface point on the dovetail rail to protect the rail from wear. The clamping assembly includes a means for retracting the buffer pad when the clamping assembly is in the disengaged position, the retraction means preferably being magnetic. Such that the buffer pad is held out of the way when mounting or dismounting the mounting assembly.

Abstract: A metal heat shield insert is provided for installation into the lower hand guard of an integrated rail system. The heat shield is received and supported in a pair of opposing mounting channels that are formed on the inside of the lower hand guard. The body of the heat shield includes a plurality of venting holes to permit air to flow through the heat shield. When the heat shield is installed in assembled relation with the hand guard, the venting holes in the heat shield are offset in location from the venting holes in the hand guard to provide an indirect venting arrangement.

Abstract: An improved mounting assembly is provided that is configured to be releasably mounted onto a standard dovetail rail profile and includes a positive index that corresponds to a fully opened position. The mounting assembly includes a boss formation that extends from one side thereof. A foot portion and an actuator arm are installed into the boss formation and serve as a means for engaging and disengaging the mounting assembly relative to the dovetail rail. An indexing formation is provided on the boss and is configured such that the indexing formation engages the clamping assembly to prevent over rotation of the foot portion and thus allowing the actuator arm to be positioned in a fully disengaged, open position where the foot portion will not interfere with removal or installation of the mounting assembly relative to the rail.

Abstract: A sling swivel component that interfaces with an S.I.R. system to allow attachment of a sling strap thereto while also having a flat head screwdriver integrated into the end of the threaded neck of the swivel body itself is provided. The sling swivel includes a swivel body and a sling swivel pivotably attached to an upper end of the swivel body. The sling or shoulder strap passes through the elongated opening of the sling swivel. The swivel body includes a threaded neck that is sized for threaded engagement within one of the threaded openings that are normally provided along the S.I.R. system such as those found in one of the optional rail segments or directly in the lower hand guard of the rail system.

Abstract: A mounting assembly for attaching an accessory to a dovetail rail interface comprising a mount body, a boss formation extending from a side of the mount body, and a clamping assembly received within the boss formation. The clamping assembly including a camming foot and an actuator arm affixed to the camming foot where rotation of the actuator arm causes rotation of the camming foot. The clamping assembly is movable between an engaged position and a disengaged position. The mounting assembly further includes a spring biased latching assembly configured and arranged to selectively retain said clamping assembly in said engaged position.

Abstract: A folding front sight for a firearm is disclosed. The folding front sight includes a base with a forward end and a rearward end. A forward sight frame at the forward end of the base is included. The forward sight frame includes a front sight post at an upper end thereof, and is movable between an upright deployed position and a stowed position. A support member has a rear end extending from the rearward end of the base and a forward end engaged with the upper end of the forward sight frame to support the forward sight frame, when the forward sight frame is in the deployed position. The base, the forward sight frame and the support member cooperate to define a triangular silhouette when the forward sight frame is in the deployed position.

Abstract: A modular integrated rail system for a firearm includes an upper hand guard having a dovetail rail extending longitudinally between the forward end and the rearward end thereof. The rearward end of the upper hand guard includes a clamp that removably secures the upper hand guard to the barrel nut of the firearm. The rearward end of the upper hand guard and the clamp include clamping surfaces configured to cooperatively engage the outer surface of the barrel nut. The upper hand guard further includes mounting channels that are used to mount accessories, such as a lower hand guard or a grenade launcher, to the upper hand guard. The rear end of the upper hand guard includes alignment tabs for automatically aligning the dovetail rail of the upper hand guard with the dovetail rail of the upper receiver during mounting. The tabs also prevent rotation of the rail system relative to the upper receiver during use.
