An adjustable tuning device includes an externally threaded mounting member having a base defining an aperture and a tuning weight having internal threads configured to mate with the externally threaded mounting member. The aperture can be configured to receive a forward portion of a gun such that a threaded protrusion extends forward of the base. The mounting member can have a rear surface configured to abut a forward-facing shoulder of the gun. The tuning weight is rotatable about the mounting member to move in a range of axial positions with respect to the mounting member and a barrel axis. The mounting member can have a skirt extending from the base. The mounting member can have an external diameter at an externally threaded portion, and the tuning weight can have a rear portion with an internal diameter less than the external diameter of the mounting member.

An assembly is configured for retaining a muzzle accessory mounted on a firearm barrel or to a muzzle adapter on the barrel, where the muzzle accessory has a mount with female threads on an inside and male threads on an outside of the mount. The outside of the muzzle adapter has male threads and a bearing surface. A locking nut has inner female threads and an inside taper located proximally of the female threads. A locking ring has a tapered outside face configured to engage the inside taper of the locking nut and an inside face configured to engage the bearing surface. When assembled, the mount is threaded onto the muzzle adapter and the locking nut is threaded onto the accessory mount with the locking ring engaging the bearing surface of the muzzle adapter and the inside taper of the locking nut.

Methods and systems are provided for a firearms suppressor adapted with blowout panels. In one example, the blowout panels may be configured to have a lower tolerance for pressure than the materials from which outer components of the suppressor are formed. During over pressure events of the suppressor, the blowout panels may rupture, thereby dissipating pressure in the suppressor.

An exciter is adaptable for use with airsoft guns to excite red tracer BBs. The exciter comprises a tube and an adapter for coupling said tube to the muzzle of the guns. The exciter also comprises a blue tracer light source supported adjacent said tube. The light source being arranged to emit light into said tube.

Suppressors for firearms are disclosed. In some embodiments, a suppression core comprises an annular cylinder surrounding a center bore, and a baffle structure surrounding the annular cylinder. The annular cylinder and the baffle structure are concentric. The baffle structure comprises a triply periodic minimal surfaces (TPMS) structure. At a transition between the annular cylinder and the baffle structure, a plurality of first openings in the annular cylinder form continuous paths with a plurality of second openings in the baffle structure. In some embodiments, a suppression core comprises an annular cylindrical shape having a center bore, the suppression core comprising a TPMS structure. The TPMS has walls within the TPMS structure. A wall thickness of the walls of the TPMS structure or a unit cell size of the TPMS structure varies within the suppression core.

The method and apparatus for a remote weapon station or incorporated into manually-aimed weapons. The methodology requires use of a muzzle velocity sensor that refines the aiming of the second and subsequent fires or volleys fired from weapon systems. When firing the first volley a weapon uses an estimated velocity and, at firing, the muzzle velocity of a projectile is measured. When firing the second volley a weapon's fire control calculates an aiming point using the measured velocity of the first volley.

An apparatus for stabilizing firearms is disclosed. The apparatus comprises a body having a left side module and a right side module secured together by a combination of locking mechanisms. An extendable rail with a support brace provided at the rear end is connected to the body of the apparatus. Further, a back securement disposed at the bottom side of the body, wherein the back securement is connected to the left side module of the body using a first side securement and the right side module of the body using a second side securement. Furthermore, a key for locking the extendable rail in a plurality of configurations is provided. Herein, the key is inserted through one or more keyholes provided in the extendable rail and a socket provided at the rear end of the body.

A firearm including a barrel bushing is disclosed. The barrel bushing provides for guidance of the slide without a need for forward rails. The barrel bushing is retained by a bushing stop that allows the slide to be removed while the recoil spring and bushing are retained on the barrel.
