A barrel mounting system for a firearm includes a longitudinal axis, a receiver, and a barrel detachably coupled to the receiver by upper and lower barrel mounting features above and below the barrel bore centerline. The lower mounting feature may comprise a clamping block compressing a lower breech end portion of the barrel against the receiver. In one embodiment, a pair of lower securement fasteners extend through the clamping block and threadably engage the receiver to draw the block into engagement with the receiver. The upper mounting feature may comprise a securement fastener compressing an upper breech end portion of the barrel against the receiver. The upper and lower mounting features form a triangular bolting pattern and balance moment forces created by the compressive forces of coupling the barrel to receiver with the fasteners.

A firearm with manually operated bolt release includes a receiver defining a longitudinally-extending cavity, a barrel, and a bolt slideably mounted in the receiver for reciprocating axial movement between a forward closed breech position in battery with the barrel and a rearward open breech position. A recoil spring biases the bolt forward towards the closed breech position. A manually actuated bolt release is pivotably mounted in the firearm and movable between an engaged position and a disengaged position. The bolt release includes a locking portion configured to selectively engage a locking recess formed on the bolt for holding the bolt in the open breech position, and disengage the locking recess for releasing the bolt to reclose the breech. In one embodiment, the bolt may be automatically disengaged from the bolt release by retracting the bolt a second time.

A trigger housing mounting system for a firearm includes a receiver having a mounting slot and cutouts which receive mounting tabs on the trigger housing. The trigger housing is slidable forward and rearward in the receiver between locked and unlocked positions. A spring-biased locking block is movably mounted on the trigger housing. During the mounting process, the locking block is movable between a non-blocking position and a blocking position which prevents removal of the trigger housing from the receiver. A related mounting method is disclosed.

A buttstock includes a mounting extension member attachable to a firearm receiver, an adjustable butt pad for varying the length of the stock, and an adjustable cheek rest for adjusting the height of the stock. The butt pad assembly is attached to the extension member by a laterally compressible clamping member operated by a double-acting cam lever having two locking surfaces and a non-locking release surface. At least one adjustment rail extends forward from the butt pad through opposing movable jaws of the clamping member. The rail can slide forward/rearward to adjust the stock length which is lockable via the cam lever locking surfaces. The cheek rest includes compressible opposing adjustment legs operated by a similarly configured cam lever in one embodiment. The height of the cheek rest may be adjusted and locked in position in a similar manner.
