Abstract: A portable firearm securement system configured to secure a firearm and prevent firing of the firearm while also being configured to be easily moveable is disclosed. The portable firearm securement system may be formed from first and second bodies for securing a firearm and preventing access to a trigger of the firearm, whereby the first and second bodies are positioned on both sides of the firearm adjacent the trigger and magazine well. Three pins extending from the first body to the second body prevent rotation of a firearm relative to the first and second bodies. Additionally, one pin extends thru the second body and includes a securement orifice through which a padlock shackle may be positioned to lock a firearm in place within the securement system. The securement system may be releasably secured to a securement object with a tether wrapped around the securement object and secured to the padlock.

Abstract: A suppressor, an integrally suppressed barrel system, and a method for coupling a suppressor to a firearm barrel are provided. In an embodiment, a suppressor is configured to have two distinct fittings, each of which provides a point of contact for coupling with a firearm barrel. The suppressor or integrally suppressed barrel system may comprise an expansion chamber with an expansion chamber baffle and wire mesh to alter the sonic characteristics of a report associated with the discharging of a firearm. In some embodiments, the expansion chamber baffle may be movable, allowing for modification to the sonic properties of a cold bore shot vis-à-vis subsequent shots. The method for coupling the suppressor to the firearm barrel includes engaging first and second threaded portions of the firearm barrel with corresponding threaded inner surfaces of first and second suppressor fittings.

Abstract: A device implementable on a firearm includes a forward assist assembly which is configured to be installed on an upper receiver of the firearm. When pressed, the forward assist assembly moves along a longitudinal axis thereof to engage with a serration cut on a bolt carrier of the firearm to push the bolt carrier forward with respect to the upper receiver when pressed. The forward assist assembly includes a modular component slidingly attachable to and detachable from the forward assist assembly.

Abstract: The present invention provides ammunition cartridge having a two piece primer insert with a flange, a polymeric middle body extending from the primer insert to a cylindrical middle body coupling region, and a polymeric projectile end having a projectile aperture mated to the polymeric middle body.
