Abstract: A firearm includes a lower receiver defining a trigger well configured to receive an action, a lower forend extending distally from and monolithically formed with the lower receiver, and an upper forend detachably coupled to the lower forend. The lower forend and the upper forend together define a channel therethrough configured for receipt of a barrel of the firearm. The lower receiver is configured to support the barrel with the length of the barrel free-floating within the channel.

Abstract: A chassis for a firearm includes a lower receiver and a lower forend that are monolithically formed with one another. The lower receiver defines a trigger well that is configured to receive an action. The lower forend extends distally from the lower receiver and defines a channel that is configured to receive a barrel.

Abstract: A universal chassis for a firearm includes sidewalls. The sidewalls define a trigger well that is configured to receive a trigger mechanism. One of the sidewalls may define a cutout adjacent the trigger well. The chassis is configured to interchangeably receive a bolt action and a barrel for a shotgun, a muzzle loader, and a rifle. The cutout is sized and dimensioned to receive a lever arm of the bolt action.

Abstract: An ambidextrous chassis for a firearm includes sidewalls and a plug. The sidewalls define a trigger well that is configured to receive a trigger mechanism. Each of the sidewalls also defines a cutout adjacent the trigger well. The plug is received within one of the cutouts of the sidewalls to seal the trigger well of the chassis. Each of the cutouts is sized and dimensioned to receive the plug.

Abstract: A chassis for a firearm includes sidewalls, a forearm, and a first rail portion. The sidewalls define a trigger well and a magazine well therebetween. The sidewalls also define a proximal portion of a channel. The forearm is monolithically formed with the chassis and extends distally from the magazine well. The forearm defines a distal portion of the channel which is configured to receive a barrel of a firearm. The first rail portion extends from the forearm adjacent the channel on a first side of the chassis. The first rail portion defines part of a rail system that is configured to securely mount an accessory directly to the chassis.
