Abstract: A firearm suppressor that includes a mount configured to connect the firearm suppressor to a barrel of a firearm. The firearm suppressor includes a first module connected to the mount. The interior of the first module is a first chamber and the first module does not include a baffle. The firearm suppressor includes a second module connected to the first module. The second module includes a plurality of baffles and at least one peripheral pathway that bypasses a second baffle of the plurality of baffles by fluidly connecting an exterior of a first baffle of the plurality of baffles with an exterior of an exterior of a third baffle of the plurality of baffles. The firearm suppressor includes an end cap connected to the second module.

Abstract: Disclosed herein is a modified rifle bolt carrier allowing a selectively openable vent/valve at the location where exhaust gas is pressurizing the bolt carrier to control carrier speed under suppressed fire in a first valve position or unsuppressed fire in a second valve position. A valve core is disclosed which may be rotated 180° to a first “open” setting for non-suppressed fire from its position in a “closed” position for suppressed fire, and a third “median” position. The modified bolt carrier will allow an operator of the firearm to adjust for a suppressor without changing the gas block or having to modify or adapt the front end or barrel end of the firearm.

Abstract: A multi-core suppressor for a firearm. The multi-core suppressor includes a housing having a first and second ends and a central main core positioned within the housing. The central main core has a first end, a second end, and a longitudinal centerline with a plurality of central baffle portions positioned adjacent to the longitudinal centerline and a projectile path through the central baffle portions. The multi-core suppressor includes a first side core positioned between the housing and a first side of the central main core and a second side core positioned between the housing and a second side of the central main core. The first side core has a plurality of first side baffle portions and the second side core has a plurality of second side baffle portions. The first and side baffle portions engage the central baffle portions to form a plurality of baffles positioned within the housing.

Abstract: A gas block for a firearm and a gas block system for a firearm. The gas block includes an upper tube connected to a lower tube. The upper tube includes a first passageway and an aperture through the upper tube opposite the lower tube. The lower tube includes a second passageway configured to receive a barrel of a firearm. A central passageway connects the first passageway to the second passageway. A gas nipple having a central bore is threaded into the central passageway. The gas nipple includes an engagement feature to engage a tool for the rotation of the gas nipple within the central passageway. The tool may be inserted through the aperture in the upper tube. The gas nipple may include a taper at the second end. The first passageway is configured to receive a gas tube, or a piston cup, and the second passageway receives a firearm barrel.

Abstract: Disclosed herein is a hand guard attachment system comprising: a barrel nut configured to be attached to a firearm; the barrel nut having an outer surface; and a cam lever rotatable from a first position allowing the hand guard to be longitudinally positioned about the barrel nut to a second position clamping the hand guard onto the barrel nut. The hand guard attachment system may be arranged wherein the hand guard is rotationally adjustable without indexing relative to the barrel nut. The hand guard attachment system may comprise a longitudinal locking system cooperating with the clamping system and prohibiting longitudinal movement of the hand guard relative to the barrel nut when engaged.

Abstract: Disclosed herein is a rotary lockup action including a firing mechanism for a firearm. The firearm including a receiver having a cavity therein configured to accept the firing mechanism. The firing mechanism comprising a bolt guide rail fixed to the inner surface of the cavity of the receiver. The firing mechanism also comprises a bolt sliding along a longitudinal axis on the bolt guide rail. Also disclosed is a change handle rotatably mounted to the bolt so as to rotate relative thereto about a vertical axis orthogonal to the longitudinal axis. The charge handle may be mounted to the bolt so as to longitudinally reposition therewith. The charge handle having a surface defining a cut therein aligned with a slot in the bolt when the bolt is in a rearward position; and wherein the surface defining a cut in the charge handle is not aligned with the slot in the bolt when the bolt is in a forward position.
