Abstract

Present embodiments relate to a modular firearm. More specifically but without limitation, present embodiments relate to a modular firearm, for example semi-automatic rifle, with various modules that provide differing functions to a semi-automatic or automatic rifle. Some of the functions include, but are not limited to, connector for ambidextrous stock folding, interchangeable magwell for changing of firearm caliber, a barrel module with evacuation chamber, and ambidextrous charging handle.

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

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

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

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.
