The inventive subject matter is directed to systems and apparatuses that are designed to work in cooperation with a firearm such that the firearm can fire a less lethal projectile. Systems can include a mounting device that clips onto a firearm, where that mounting device also include mounting posts. The mounting posts protrude from an end of the mounting device, and the mounting posts are designed to couple with mounting holes on an associated slug. Slugs of the inventive subject matter thus feature mounting holes and a center-bored hole that is designed to capture a bullet that is fired from a firearm that the system is coupled to. When a bullet is captured by a slug, an inelastic collision takes place that causes the slug to leave the firearm at around 20% of the bullet's original speed.

A locking firearm silencer mount or firearm muzzle accessory mount improvement system and method. The coupling device provides an internal thread and sealing taper, as well as an actively sprung locking collar with one or more locking positions. The muzzle device provides a thread and sealing taper operatively associated to the mount socket. The threads on the mount and muzzle accessory effectuate mating between the locking mount and the firearm muzzle accessory in a single axial orientation.

A muzzle accessory for installation on a barrel of a firearm is provided. The muzzle accessory includes an accessory body having a through-channel sized to receive the barrel of the firearm; and a locking member structured to engage the groove of the barrel to lock the muzzle accessory to the barrel.

A firearm includes a muzzle device. The muzzle device includes a muzzle adapter and a muzzle attachment. The muzzle attachment suppresses noise and/or redirects gases and recoil. The firearm utilizes recoil operation to cycle such that the barrel reciprocates inside a handguard of the firearm during cycling. The muzzle adapter is attached to the handguard and receives the barrel therein. The muzzle attachment is secured to the muzzle adapter such that the muzzle of the barrel remains longitudinally in the muzzle adapter during discharge and cycling of the firearm.

Methods and systems are provided for firearm sound suppressors including a gas deflector. In one example, a suppressor comprises a housing, a projectile entrance, a projectile exit, one or more baffles, and a deflector chamber. The deflector extending outward from the housing and the deflector curving around a central axis of the suppressor.

A compensator device for manipulating and reducing the effects of firearm muzzle lift and a lower receiver for manipulating environmental effects on firearms and firearm operators.

Firearms having threaded barrels with hidden threads. The barrel has a threaded portion disposed within the slide of the firearm when the firearm is in battery so that the muzzle end of the barrel is aligned with the muzzle end of the slide. The barrel is configured to couple with a barrel attachment, such as a thread protector, such that the coupling portion of the barrel attachment is disposed within the slide of the firearm when the firearm is in battery.

A Glock compensator integral with a barrel, and a slide assembly allow escaping gases to dampen recoil associated with firing a Glock firearm. The Glock barrel is removed from the front of the firearm allowing for the integrated compensator at the front of the firearm. Various features, including a lock design, debris port, swept back side ports, height offset, nose ring design and mass-reducing rear cutout, result in an efficient and effective integrated compensator suitable for 4.sup.th and 5.sup.th generation Glock firearms. The compensator and barrel may be fabricated from the same piece of billet. A pair of side rails may be positioned and configured to slidably receive a slide assembly.

The utility model is related to a rifled firearm suppressor, a.k.a. a silencer, to be mounted in the front section of the rifled firearm barrel and intended to reduce the harmful effects of the gases upon having the bullet exiting/leaving from the muzzle section, thus achieving reduction of noise and recoil when firing. It consists of a rear discharge chamber 11 and a front extension chamber 12; the two chambers 11 and 12 are separated from each other by a dividing groove 3, while inside the core 4 there is a removable connecting sleeve 16 located/mounted to connect to the barrel of the firearm. Also, at least two outlet openings 10 are created symmetrically axially with respect to the axis of the suppressor at the forehead of the front section of the discharge chamber 11.
