摘要： A suppressor baffle and a suppressor for a firearm. The suppressor includes a firearm attachment portion, a sleeve portion, and a baffle assembly with a plurality of baffles. At least one of the baffles includes a tubular body with a proximal exterior surface. The proximal exterior surface has a plurality of spaced-apart annular ridges. A first annular ridge includes a first annular compression surface and a first annular expansion surface, and a second annular ridge includes a second annular compression surface. The ridges are shaped and arranged to define a convex first expansion corner between the first annular compression surface and the first annular expansion surface, and a concave first compression corner between the first annular expansion surface and the second annular compression surface. Gas flowing along the proximal exterior surface expands at the first expansion corner and compresses at the first compression corner to dissipate energy in the gas.

摘要： A firearm using blowback action has a barrel which is movably mounted within a shroud which is fixedly mounted on the firearm's frame. A gas space is formed between the barrel and the shroud by a difference between the inner diameter of the shroud and the outer diameter of the barrel. At least one gas port provides fluid communication between the bore of the barrel and the gas space. During firing of a cartridge, pressurized gas in the gas space applies a force to the barrel which moves relatively to the shroud away from the muzzle end of the firearm to engage a slide or bolt, helping to move it out of battery and extract the spent cartridge casing. Gas is vented to the atmosphere through a gas vent defined between the barrel and the shroud in fluid communication with the gas space.

摘要： A sear mechanism for a firearm pivotably mounts a sear body on a sear lever which is pivotably mounted on the firearm frame. An actuator lever is also pivotably mounted on the frame. The actuator lever is pivoted by a trigger bar connected to the firearm's trigger. Pivoting of the actuator lever when the trigger is pulled allows the sear lever to pivot. Pivoting of the sear lever allows the sear body to fall off of a surface on a striker, releasing the striker to discharge the firearm.

摘要： A trigger return spring assembly mountable on a frame of a firearm includes a trigger mounted on the frame pivoting about a first axis of rotation. A trigger bar attached to the trigger pivots relative to the trigger about a second axis of rotation fixed on the trigger. A bore extends through the trigger along a third axis oriented transversely to and positioned between the first and second axes of rotation. A plunger extends through the bore and is movable along the third axis. A first end of the plunger is attached to the trigger bar and a second end has a retaining surface oriented transversely to the third axis. A shoulder is positioned within the bore proximate to the trigger bar. A compression spring captured within the bore, between the shoulder and the retaining surface, exerts a force pushing the retaining surface away from the shoulder.

摘要： A shotgun has right and left magazines from which ammunition may be fed to the action using a selector mounted on a movable fore-end chassis whose motion cycles the action. An interrupter prevents the selector from switching between magazines unless the action is in battery with the fore-end chassis fully forward toward the muzzle end of the shotgun. Respective right and left outer cut-offs on the magazines cooperate with an inner cut-off to ensure proper coordination of ammunition feed as the action is cycled by motion of the fore-end chassis. The outer cut-offs are also manually operable to permit removal of ammunition from the magazines without cycling the action.

摘要： A magazine for feeding ammunition to a firearm includes a tube surrounding a longitudinal axis and defining a central space for receiving the ammunition. The tube has first and second ends. A follower is slidably movable within the tube. A butt plate is removeably attached to the first end. The butt plate defines a bore. A plunger is movably positioned within the bore and includes a first mounting cam. A first catch, mounted on the butt plate, is engageable with the tube proximate to the first end. The first catch is movable relative to the butt plate in a direction transverse to the longitudinal axis. The first catch includes a cam follower engageable with the first cam. A spring acts between the plunger and the follower for biasing the plunger toward the butt plate and the follower toward the second end.

摘要： A mounting mechanism has a base upon which a rotating cam is mounted. The cam has a lobe which extends beyond the perimeter of the base when the cam is in a first position and remains within the perimeter of the base when the cam is in a second position. A detent is used to lock the cam in the first position. The detent includes a leaf spring positioned on the cam which defines a kink. The kink is engageable within a niche in the base when the cam is in the first position. An accessory attached to the mounting mechanism may be attached to a structure using the mounting mechanism. The base fits within a slot in the structure and the lobe of the cam engages the structure when the cam is in the first position to lock the mounting mechanism and the accessory to the structure.

摘要： A breech cover interlock coordinates the motion of a breech cover with the motion of the fore end of a pump action firearm. The interlock features an action bar which is connected to the fore end and has a catch which is engaged by a latch mounted with the cover on a movable buttstock. Engagement between the catch and the latch prevents the buttstock and cover from moving and thereby exposing the firearm's breech while the firearm's action is in battery as evidenced by the position of the fore end. Motion of the fore end out of battery disengages the latch and catch and permits the cover to be moved out of overlying position with the breech to permit access to the breech to clear a malfunction.
