Abstract

A modular bolt assembly may include a bolt body, a striker assembly, and one or more removable bolt, head having a floating fixing pin, The removable bolt head may have a cartridge engagement surface, a back end that removably mates with a bolt body, and a floating firing pin with a front end that contacts a cartridge primer, and a rear end that receives force from the striker assembly. Bolt heads may be included for different caliber cartridges, allowing the modular bolt assembly to be used with different types of ammunition, the floating firing pin prevents the striker assembly from directly contacting a chambered round without the bolt head, thereby preventing catastrophic failure during use if a boll head is not present and properly positioned.

Abstract

A semi-automatic rifle is configured to fire single rounds of ammunition via a magazine or a belt of ammunition. A receiver cover pivots open to receive the first round of a belt of ammunition or a magazine can be inserted in a magazine well. The rifle operates using a closed bolt firing cycle, with a sliding hammer that, on its return from recoil after firing a first round, is caught by a sear regardless of whether the trigger is still in the pulled position. The trigger must be fully released before a second round can be fired.

Gas block valve stem for modifying the firing rate of a machine gun

Abstract

A reversible modification to the gas block of a machine gun reduces the rate of fire to the machine gun's design rate for use when a suppressor has been added to the barrel and which suppressor would, without the present modification, elevate the firing rate from the machine gun's design rate. The modification is the use of a stem inserted into the bore of the gas block nozzle to further limit the combustion gas being delivered to the machine gun's operating group. A hole formed in the stem restricts gas flow. The stem seats against the gas block nozzle and is held in place by the cap covering the gas block but may alternatively be held in place in several alternative ways described. Removal of the cap allows the stem to be removed from the gas block when the suppressor has been removed from the machine gun barrel.

Sound suppressor for a firearm

      
Application Number 14521875
Grant Number 09175920
Status In Force
Filing Date 2014-10-23
First Publication Date 2015-05-21
Grant Date 2015-11-03

Abstract

A sound suppressor for a firearm with a high rate of fire, such as a machine gun, conceals the location of the firearm during heavy use by rapidly dissipating heat through a foamed carbon core. A sound suppressing baffle core is coaxially located within a tubular housing, having flared ends extending beyond the core. An inlet nozzle and exit place close the ends of the suppressor and are held in place with threaded collars. The terminal portions of the collars are beveled, as are the corresponding terminal portions of the nozzle and end plate, and are used to capture the flared portions of the ends of the tubular housing. Diagonally opposing recesses in the collars enable their removal with a spanner wrench, along with the other components for maintenance and replacement. The suppressor lasts longer and has a less visible heat signature used in sustained fire on a machine gun.

Coupler system for attaching blank adaptor and the like to a flash hider

Abstract

A coupling system attaches a device such as a blank adaptor or a sound suppressor to the flash hider of a firearm. The device is slid over the flash hider until a set of flat surfaces on it are aligned with a set of holes in the device. Camming latches are held in the holes in the device. The collar carried by the device is then threadably advanced to a locking position with respect to the device where it presses the camming latches into secure engagement with the flat surfaces on the flash hider. Unthreading the collar to the unlocked position allows the camming latches to be moved radially when the device is to be removed or rotated. A spring lock prevents the collar from rotating during use, particularly during firing of the firearm but may be released to rotate the collar between locked and unlocked positions.

Abstract

A flash hider, a sound suppressor and a quick-disconnect coupler that holds the sound suppressor to a flash hider is disclosed. The quick-disconnect coupler enables the suppressor to be attached to the flash hider so that the hider forms a nozzle at the entrance to the sound suppressor to facilitate the operation of the suppressor. The coupler includes a collar that threads to the first part of the suppressor over plural holes formed therein. Camming latches set in these holes are held firmly against flat surfaces on the exterior of the flash hider by the collar. A spring lock holds the collar against rotation until it is released.

Abstract

A bipod for a light-weight machine gun is disclosed. The bipod has tubular telescoping legs with large ground-engaging feet that may be extended and retracted to discreet locking positions. The bipod has a spring-based system that allows a user to pivot the bipod legs about cylinder-in-a-cylinder pivot pins, either towards or away from the barrel muzzle with one hand, thus giving 180 degrees of travel. The bipod is attachable to a machine gun with a round yoke using a stepped screw and compression spring that assures yoke remains tightly secured to body, but rotatable for traversing, during extended use.

Sound suppressor

Abstract

A sound suppressor suppresses sound and flash by creating interacting paths of gas. While a first portion of the gas follows a first path through the suppressor, a second portion of the gas is diverted radially from the first path to a second path and then repeatedly made to cross the first path by a series of baffles with alternating radial passages so that the two portions of gas interfere and interact with each other, and therefore quickly give up much of their kinetic energy before they exit the suppressor. Preferably, the baffles defining the second path impart a swirl to the second portion of gas to cause the present suppressor to flush itself of carbon and metal particles. The interaction of the two portions also accelerates completion of combustion of the gas to thereby reduce flash.
