US12352518 - Gas operating system for low energy ammunition

A gas operating system for a firearm for use with low energy ammunition that includes a barrel having a maximum pressure experienced at a maximum pressure location when firing the low energy ammunition where a gas port is positioned distally from the maximum pressure location in a region of the barrel that experiences between 90% of the maximum pressure and 40% of the maximum pressure, a gas block on the barrel and a tube connecting the gas block to a bolt carrier, where the gas block directs energy from combustion gas pressure vented through the gas port to the bolt carrier via the tube.

The patent describes a gas operating system designed for firearms that utilize low energy ammunition, featuring a barrel with a strategically placed gas port to optimize pressure management. This system includes a gas block and a connecting tube that channels combustion gas pressure to the bolt carrier, enhancing the firearm’s operation with reduced energy ammunition.

Claim 1

A gas operating system for a firearm adapted for use with low energy ammunition, wherein the firearm includes a bolt carrier, the system comprising: a barrel having a breech, a muzzle, a bore and a first gas port, wherein the barrel has a maximum pressure experienced at a maximum pressure location when firing the low energy ammunition and wherein the first gas port is positioned in a location that is distal from the maximum pressure location in a region of the barrel that experiences between 90% of the maximum pressure and 40% of the maximum pressure; a gas block disposed on the barrel; and a tube operatively connecting the gas block to the bolt carrier, wherein the gas block is configured to direct energy from combustion gas pressure vented through the first gas port to the bolt carrier via the tube. a barrel having a breech, a muzzle, a bore and a first gas port, wherein the barrel has a maximum pressure experienced at a maximum pressure location when firing the low energy ammunition and wherein the first gas port is positioned in a location that is distal from the maximum pressure location in a region of the barrel that experiences between 90% of the maximum pressure and 40% of the maximum pressure; a gas block disposed on the barrel; and a tube operatively connecting the gas block to the bolt carrier, wherein the gas block is configured to direct energy from combustion gas pressure vented through the first gas port to the bolt carrier via the tube.
