Abstract: A system for manipulating an engagement interface associated with securing accessories to a firearm. The system includes at least one accessory mount adapter that includes a first side that is constructed to cooperate with an engagement interface defined by a structure, such as a hand guard, that is securable to a firearm. A second side of the adapter defines a second engagement interface that is different than the first engagement interface and is configured to removably cooperate with a firearm accessory.

Abstract: A system or assembly for securing accessories to an underlying firearm assembly. The accessory mounting assembly includes a base that is constructed to be secured to a mount plate that is securable to an underlying firearm. An accessory support is securable to the base and moveable in a horizontal lateral direction relative thereto. An engagement or interface arrangement is provided between the base and the accessory support such that the accessory support can be translated in a lateral direction that is orthogonal to a bore of the underlying firearm and is constructed to provide vertical association of discrete accessory supports relative to the base.

Abstract: A mount assembly for securing accessories to an underlying firearm assembly. The mount assembly includes a base that is constructed to be secured to an underlying firearm and an accessory support that is moveable relative to the base. An interface arrangement is provided between the base and the accessory support such that the accessory support can be rotated relative to the base between a first orientation that is laterally inboard of the base and a second orientation that is laterally outboard of the base to accommodate break-action operation of an underlying firearm when the accessory mount assembly is secured to the firearm.

Abstract: A gas tube assembly for semiautomatic firearms is defined by a body having a first end, a second end, and a passage formed through the body between the respective ends. The first end of the body of the gas tube is constructed to cooperate with a gas block and the second end of the body is constructed to cooperate with a forward facing end of a receiver assembly. A first projection and a second projection each extend in a respective outward radial direction from the body proximate the second end of the body and a respective adjuster is associated with each respective projection. The adjusters are configured to movably cooperate with the respective projection to align the second end of the body relative to the receiver assembly.

Abstract: A handguard mount assembly and method of forming a handguard mount assembly that includes a mount clip that is defined by a body having a first portion constructed to be received in a slot defined by hand guard and define a smallest diameter associated with a receiver end of the hand guard. The body of the mount clip preferably includes a second portion that radially indexes the mount clip, and a hand guard associated therewith, relative to a receiver associated with the underlying firearm such that the mount clip defines a maximum compression associated with the hand guard and prevents rotation of the hand guard relative to the receiver when assembled.

Abstract: A hand guard mount assembly and method of securing a hand guard to a firearm in a manner that resists rotation and/or longitudinal translation of the hand guard relative to the underlying firearm. The hand guard mount assembly includes a mount clip that is defined by a body having a first portion and a second portion. The first portion of the clip is constructed to be received in a slot defined by a handguard and defines a smallest diameter associated with a receiver end of the hand guard. The second portion of the clip radially and/or longitudinally indexes the mount clip, and a hand guard associated therewith, relative to at least one of a barrel nut, a barrel, and a receiver associated with the underlying firearm.

Abstract: Systems and methods for securely mounting devices and/or accessories to vehicles and/or other supporting structures. The systems include a shaft having a longitudinal axis. A pair of clamp bodies cooperates with the shaft so that a distance is defined between the clamp bodies. A lever is engaged with the shaft and operable to alter the distance between the clamp bodies. A lock supported by the lever movably engages the shaft and maintains the orientation of the clamp bodies relative to one another by maintaining an orientation of the lever relative to the shaft so that the lever can only be operated when the lock is disengaged from the shaft.
