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.

A wiped muzzle device, such as a compensator, brake or flash suppressor. The wipe improves the function of the muzzle device by forcing muzzle blast gases through the ports or vents to either counter the force vector created by the muzzle blast gases or alter the mixing of gases to reduce muzzle flash.

A measurement and data integration system for the preparation of a firearm, to fire an accurate, precise shot, incorporating a tubular component containing two sensors to measure the speed of the projectile, further including a subsystem for the detection of the impact thereof and the measurement of the time of flight of the same, a subsystem for the measurement of the angles of inclination and cant; a calibration subsystem, a subsystem for communication with weather stations which consults and receives in real time the meteorological variables, as well as a microprocessor with a first operational programme that measures, requests, stores and manages all the aforementioned signals, and a second programme that includes an interface with the user.

A firearm suppressor (1) also known as a moderator includes a number of coaxially joined steel baffles (20,40,60) for dissipating discharge gasses. Each baffle can have an internal funnel structure (30) having a central aperture (31) through which the firearm projectile passes. Adjacent funnel structures form interconnected primary and secondary chambers connected by a port (28) through a flange (37) separating the chambers. A notch (36) in the central aperture of one funnel structure directs flow toward the port (48) on the diametrically opposite side of the next funnel structure. A radial hole (29) through the funnel structure connects successive primary and secondary chambers. The flange is axially located to be radially inward from an overlapping joint between two adjacent baffles in order to provide structural support to the joint.

A system for determining the muzzle velocity of a firearm includes a firearm having a barrel and a gas block. A first sensor is arranged at a gas block and is configured to determine a change in pressure within the gas block. A second sensor is positioned at an end of the barrel of the firearm for detecting a pressure wave produced by a projectile fired by the firearm. A control unit is in communication with the first sensor and the second sensor and is configured to determine a velocity of the projectile based on information received from the first sensor and the second sensor.

Some embodiments include an optic guard for a firearm, the optic guard including: a frame; and a bracket having a side to attach to a firearm assembly, the bracket integrally formed with the frame or fixably attached to the frame; wherein the frame is arranged to cover part of a front of an optic housing when the side of the bracket is attached to the firearm assembly. Other embodiments may be disclosed and/or claimed.
