Abstract: A system for securing a barrel to a receiver of a rifle is provided, the barrel having a barrel axis, a muzzle end and a receiver end, the system comprising a barrel extension having a barrel end and a receiver end, the barrel extension having internal threads at its barrel end for receiving external threads on the barrel, wherein the barrel extension is tapered at the receiver end to mate with a corresponding tapered aperture in the receiver, whereby urging the barrel extension into the receiver, seats and aligns the barrel within the receiver.

Abstract: A system for securing a barrel to a receiver of a rifle includes a barrel extension and a locking wedge. The barrel extension receives threads on the barrel and has a protuberance. The locking wedge is secured in an aperture in the receiver by a fastener. The locking wedge has a side parallel to the aperture, and a cam side disposed at an angle. The locking wedge is movable in a direction perpendicular to the barrel axis. The cam side is disposed against the protuberance. Tightening the fastener causes the cam side of the locking wedge to urge the protuberance of the barrel extension along the barrel axis in a direction away from the muzzle end of the barrel into the receiver.

Abstract: A drop safety trigger assembly is provided having a fire control housing mounted in a receiver, a rotatable sear, a rotatable sear stop, and a sear release. When a force by a user is applied to the trigger shoe, the sear stop rotates at its pivot point against the force of the trigger spring to cause a sear stop protuberance to apply a force to an upper surface of the sear release to release a projection of the sear release from the notch of the sear to cause the sear to rotate due to the force of the firing pin spring on the second end of the sear to cause the first end of the sear to disengage from the firing pin to initiate a discharge of the rifle. When no force by a user is applied to the trigger shoe to rotate the sear stop, but when the sear projection of the sear release disengages from the notch of the sear, the sear projection of the sear stop engages the notch of the sear to prevent a discharge of the rifle.

Abstract: A firearm with a tool-less adjustable trigger pull. The adjustment may be facilitated with a thumb rotatable wheel for tool-less tension adjustment of a trigger tension spring. The rotatable wheel may be accessed by snapping a trigger guard away from a stock of the firearm. Accordingly, the force required to actuate the trigger can be adjusted to the user's preference without having to remove the trigger assembly from the stock, and without need for external tools or accessories.

Abstract: A bolt action firearm that cocks the firing pin upon closing the bolt and includes a cam pin for a high velocity rimfire cartridge. In one embodiment, actuating the main spring while closing the bolt, instead of while opening the bolt, provides added safety against misfiring. A safety system is provided for the trigger mechanism and a robust connecting system for the stock.

Abstract: A bolt action firearm that cocks the firing pin upon closing the bolt and includes a cam pin with dual heads for a high velocity rimfire cartridge. In one embodiment, actuating the main spring while closing the bolt, instead of while opening the bolt, more uniformly distributes the physical energy required by the user over the bolt actuation cycle. The dual heads of the cam pin provide symmetric reactive forces with dual cam slots, thereby preventing the cam pin from skewing or canting within the cam slots. A safety system is provided for the trigger mechanism and a robust connecting systems for the stock.
