Abstract

Firearms and barrel assemblies are provided herein that include a barrel assembly having a barrel having a proximal end and a distal end comprising a muzzle. The barrel also includes a chamber defined in the proximal end. The chamber includes a distal end and a proximal end. A bore extends distally from the distal end of the chamber. The bore defines a central axis of the barrel assembly. The barrel assembly also includes a barrel extension extending from the proximal end of the barrel. The barrel extension has a distal end and a proximal end. The barrel extension defines a bolt receiving recess in communication with the chamber. The barrel extension further has a barrel vent channel defined therein in communication with the bolt receiving recess. The barrel vent channel is defined in the barrel extension in a direction that is transverse to the central axis of the barrel assembly.

Abstract

Ejection assemblies, actions including such ejection assemblies, and firearms including such actions and/or ejection assemblies are provided herein. At least one ejection assembly is provided that is configured to facilitate forward ejection of spent cartridges when a forward-ejection guide cover is in place on a receiver, and to allow for side ejection of spent cartridges when the forward-ejection guide cover is out of place on the receiver. Such a configuration may allow for reliable ejection and access to the action for clearance of jams or malfunctions while providing flexibility with forward or conventional side ejection.

• F41A 15/16 - Cartridge extractors, i.e. devices for pulling cartridges or cartridge cases at least partially out of the cartridge chamberCartridge ejectors, i.e. devices for throwing the extracted cartridges or cartridge cases free of the gun for bolt-action guns the ejector being mounted on the breech housing or frame

Abstract

A suppressor system includes at least one inner core having a core bore defined therein, the core bore having a nominal core bore diameter. The inner core also includes a core-coupling portion. A plurality of muzzle brakes that each includes a bore having a nominal brake bore diameter. Each muzzle brake includes a brake-coupling portion. The inner core is configured to allow the brake-coupling portions of muzzle brakes having nominal brake bore diameters that are equal to or less than the nominal core bore diameter to couple to the core-coupling portion and to prevent the brake-coupling portions of muzzle brakes having nominal brake diameters that are greater than the nominal core diameter from coupling to the core-coupling portion.
