Now you have all the pressure in that suppressor exiting both out the front and the back. 03- A combined retrofit direct drive gas piston system, for use with M-16 rifle and other Also eliminates problems of the original gas impingement system. Further more, none of these systems operate inside an easily attached structura AR-15s can use two operating systems: direct impingement or gas piston. Read our blog to learn the pros and cons of each. One of the first decisions you will need to make is which type of operating system you need – direct gas impingement or piston system.

Click to Gas Piston Technology – How do the new piston technologies work? Gas piston technology was first used in modern firearms by Mikhail Kalashnikov on the AK-47. While similar at first blush to direct impingement systems, there are a few key differences in operation. The firing process again begins with propellant gases being bled into the barrel.
NUREG/CR-6042, Rev. 2, "Perspectives on Reactor Safety".
Gas piston AR-15s are heavier and have a stronger recoil. On the direct impingement gun, the gas key just directs the flow of gas to the bolt. On a piston gun, the “gas key” equivalent part takes the hit from the connecting rod and pushes the bolt carrier group backward, initiating the same function as with a regular AR-type rifle. Note how clean this operating rod is.

Gas piston. While heavier than direct impingement models, gas piston AR 15 rifles run considerably cooler and considerably cleaner due to an absence of gas rerouted back into the rifle. Because they’re not as prone to ammunition variations, piston rifles won’t misfire as much as direct-impingement rifles. And, since the operating rod does a lot of the work, rather than the gas itself, it promotes a cleaner, cooler system that better handles the intensity of firing a round. The biggest drawback to a piston AR is that they’re less accurate than direct impingement systems since there’s a rapidly rotating operating rod that affects barrel harmonics and movement. Direct impingement makes use of a gas block, a gas tube, and connects with the gas key on top of the bolt carrier. With only two working parts this is a pretty simple design for anyone to understand.
Specifically, we’ll weigh in on the direct impingement versus gas piston versus blowback debate so that you can be sure to get the gas system that best meets your needs. So, let’s get to it!

Direct gas impingement is where the gas simply strikes (impinges on) the bolt carrier, imparting momentum which drives it back. The Ljungman is the classic example OTHER than the MAS series that utilizes this method of operation.

Unlike conventional gas-operated firearms, direct impingement does away with a separate gas cylinder, piston, and operating rod assembly. Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms.In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber.Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. Direct gas impingement, for example in the AR-15 and similar, takes the expanding gas from the fired round and siphons off a tiny portion through a tiny hole in the barrel, through the gas block, rearward through the gas tube and back to the bolt carrier group's gas key, which provides the force to move the BCG rearward, cycling the action.

Both systems have advantages , disadvantages, and characteristics that become a matter of preference or need. I will attempt to break down the major areas of concern.

The gas works the piston, which gets the carrier moving. That may not seem like much of a difference, but some people swear by one operating system over another. Direct Impingement and Gas Piston are two methods of gas-operation that provide energy to operate auto loading firearms. In this case, the AR-15 platform. In both systems, gasses from the firing of the cartridge are harnessed through a port in the barrel and are used to operate the action.
