摘要： System for a multi-caliber self-loading action. Specifically, the system is comprised of a multi-position locking assembly and a self-regulating gas assembly. The multiposition locking assembly is comprised of a bolt carrier, a spring, a bolt, a lock, and a cam assembly. The cam assembly will interface between the bolt carrier and the bolt to rotate the bolt through the bolt carrier. The lock will interface with the bolt, to lock the bolt in at least one locked position based on the caliber of the round inserted. The self-regulating gas assembly directs gas from the gas regulation to at least one piston cup, which will then cause the piston to act on the multi-position locking assembly.

摘要： An adjustable gas block for a firearm comprises a housing adapted to be attached to a barrel of the firearm. The housing has a first passageway adapted to be aligned with a gas port in a barrel of the firearm and a second passageway adapted to receive a gas tube of the firearm, such that a bore of the barrel, the gas port of the barrel, the first passageway, and the gas tube are in fluid communication. A valve member is mounted in the housing for forward and rearward sliding movement and has a first portion and a second portion. The first portion has an upwardly facing surface having a radius of curvature that closely approximates a radius of curvature of an outer diameter of the gas tube, and the second portion has threads. A nut is carried by the housing for rotational movement and has threads mating with the threads on the second portion of the valve. Rotating the nut in a first direction translates the valve member forwardly and rotating the nut in a second opposite direction translates the valve member rearwardly. The axial position of the first portion of the valve member controls the amount of gas passing from the first passageway to the gas tube by completely opening, partially opening, or completely closing the first passageway.

摘要： A gas block assembly may include a gas block including a gas port to receive gas provided by a gas port of a barrel; a tapered fastener opening; and a tapered fastener insertable in the tapered fastener opening, the tapered fastener including: a length further including a tapered section to contact a sidewall that defines the tapered fastener opening; and means for rotationally driving the tapered fastener into the tapered fastener opening. In other embodiments, an adjustable gas block includes sealing ring(s) on a groove in a rotationally actuated gas metering shaft.

摘要： A gas block for AR-platform firearms is provided which is easier to install and index on a barrel of the firearm by utilizing a wedge (e.g., collet) system. The body of the gas block may therefore be relatively precisely circular, allowing for easy movement into position on the barrel of the firearm. The gas block is stronger, tighter, more durable, and more reliably stays in place than prior art gas blocks. In one embodiment, the gas block eliminates forward gas leakage from between the gas block and barrel. The gas block is interchangeable with standard prior art gas blocks commonly found on barrels of existing AR-platform firearms. The gas block is also compatible with low profile and MLOK handguards for AR-platform firearms.

摘要： A firearm including a barrel, receiver, indirect gas system and an adjustable gas block designed to interface with the indirect gas system is provided. Four indexable positions of adjustment are provided for on the adjustable gas block. Positions of adjustment are selected based on the use of a silencer, use of under-powered ammunition, the presence of un-burnt powder and debris in the host firearms operating system, or if the weapon is being fired under “ideal” circumstances. The provided gas block is designed to function with an indirect gas operating system. Excess gas from the operating system is not vented from the gas block thereby generating excess flash and sound. No tool is required to manipulate the adjustment mechanism of the gas.
