| 204 | Annular piston system for rifles | US13658712 | 2012-10-23 | US08746126B2 | 2014-06-10 | Jing Zheng |
| An annular piston system for a firearm comprises a barrel, a gas block assembly, a piston, and a spring. The barrel has multiple sections lengthwise, one of the sections having at least one gas port hole to vent gas from the barrel. The gas block assembly is disposed annularly around the barrel and is adjustable to control an amount of gas flowing out of the barrel through the at least one gas port hole. The piston is disposed annularly around the barrel and can move longitudinally along the barrel in response to being pushed by the gas flowing out of the barrel. The spring is disposed annularly around the third section of the barrel and coupled to the piston. The spring limits a distance that the piston can move longitudinally along the barrel when the piston is pushed to move by the gas flowing out of the barrel. | ||||||

| 206 | Modular fore-end rail/hand guard assembly system for firearms with selectable heat dissipation characteristics | US13006083 | 2011-01-13 | US08448367B2 | 2013-05-28 | Scott W. Samson; Jonathan Bernashe |
| A modular fore-end rail assembly for mounting onto a firearm includes a hand guard and a bushing element that combines with an end portion of the hand guard to encircle the standard barrel nut, thereby supporting the entire assembly without requiring modification to the standard barrel nut. The thermal transfer characteristics of the material from which the bushing element is manufactured may be selected to either increase or decrease the rate at which heat is transferred from the barrel nut to the hand guard allowing for rapid changes of bushing elements and, therefore, rapid and selective changes in the heating rate of the hand guard. | ||||||

| 209 | Thermal insulation jacket for a gun barrel | US12290808 | 2008-11-04 | US08347773B2 | 2013-01-08 | Gert Schlenkert; Eckehard Bohnsack; Alexander Tekin |
| A thermal insulation jacket for a gun barrel, especially a cannon barrel, where the thermal insulation jacket includes a metal jacket that surrounds the gun barrel. In order to prevent uneven heating of the surface of the gun barrel within the thermal insulation jacket, an additional area that is especially effective at reflecting thermal radiation is provided on the inner surface of the metal jacket that lies opposite the underside of the gun barrel, so that when the gun barrel heats, the temperature differences between the upper side and the underside of the gun barrel are at least partially compensated. For this purpose, a reflective film is provided as the area that is a good reflector of thermal radiation. This reflective film is adhesively attached to the metal jacket. | ||||||

| 217 | Weapon with rotating barrel | US10101359 | 2002-03-18 | US06679156B1 | 2004-01-20 | Samir A. Danou |
| A weapon for firing a projectile is provided that includes a receiver within which is disposed a loading mechanism for loading and unloading the weapon. A feed system supplies the loading mechanism with ammunition and a firing mechanism releases the loading mechanism for loading and firing the projectile. A barrel is rotatively secured to the receiver and preferably includes a rifled bore that imparts a gyroscopic spin on the projectile and a rotational force on the barrel causing the barrel to rotate as the projectile is fired. In a preferred embodiment, the barrel is provided with a plurality of blades that capture air and generate airflow across the weapon and barrel to cool the barrel. | ||||||
