The system has a number of benefits and shortcomings, it simplifies a weapon’s action significantly (for instance the MAS-49 has just six moving parts) and reduces wear on operating parts. A gas piston system is fairly similar to direct impingement in that the force of the gas pushes the bolt carrier back to cycle a new round into the chamber. The difference is that a gas piston system works by forcing gas into a separate cylinder rather than using a gas tube. 2019-08-09 2019-07-24 2018-03-26 2017-04-19 2018-08-24 2019-08-21 In a traditional direct impingement AR-type rifle, the gas that enters the bolt and carrier area are HOT. Predictably, those parts, and the surrounding upper receiver, get hot pretty quickly. Unless you’re planning to pull the bolt and carrier out with your bare hands immediately after unloading a … 2012-09-12 Direct Impingement Means that this gas operates DIRECTLY on the bolt and bolt carrier rather than through a piston rod, extension, or other such mechanical connecting rod. The AK-47 is interesting in that the piston rod is a functional part of the bolt carrier being affixed albiet loosely sometimes. 2019-07-03 2019-12-29 Direct Impingement vs Gas Piston.
piston driven operating system debate and does not discuss piston guns at all. It is specifically dealing with a 14.5”AR-15 upper receiver with .062” gas port that’s as close to a Mil-Spec M4/M4A1 upper as I could find on the civilian market. Once fired, the direct impingement system bleeds propellant gases through a small hole in the barrel, which is channeled through a tube where it can directly contact or impinge the bolt carrier mechanism. At this point, the gas pushes the bolt carrier to the rear of the rifle, extracting and ejecting the spent case. This invention is a true expanding gas system instead of the conventional impinging gas system. By utilization of a metered amount of gas from the barrel, the automatic rifle mechanism is less sensitive to different firing pressures caused by variations in the propelling charge. Unlike Eugene Stoner's original direct gas impingement ("DI") design, the Revolution has POF's "Regulated Short-Stroke Gas Piston System." Rather than spent gas from a fired cartridge being sent down a tube directly to the bolt carrier and into the receiver as with a standard DI gun, in a gas piston system, the gas acts on a piston head positioned over the gas port.

gas piston debate. With the gas impingement system, gas is diverted from the barrel through a tube and back into the upper receiver to operate the action.

For the uninitiated, direct blowback is a method of operating by means of a heavy bolt/carrier and stiff recoil spring. 9mm (115gr vs 124gr vs 147 HP) The gas
