2010-04-13 · The first and most important reference mark is the fact that the Stoner-designed AR with a direct gas impingement system is by far the longest serving military service rifle in U.S. history, but

After the procedure is complete, the gas pushes the piston back into the receiver, which in turn moves the bolt carrier group back. Stoner’s design famously used in the AR-10 and AR-15 differs from early direct impingement systems in that the gas is tapped from the barrel and directed, through a gas key, into a chamber to the rear of the bolt, inside of the bolt carrier. The bolt then travels rearward with excess gases being vented off out of the bolt carrier group. The gas operating system 100 is a direct gas impingement system and includes a gas channel carrier rail 120 and a bolt carrier group 140.

Direct gas impingement

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. 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. Gas piston is a different concept but essentially completes the same function with an adjustable gas block, in which the gas force is used and the excess expelled. The gas then pushes the piston system and escapes out of the gas block, instead of going back to the receiver with the help of a tube as is done in direct impingement system. After the procedure is complete, the gas pushes the piston back into the receiver, which in turn moves the bolt carrier group back.

Simple construction, inexpensive, nothing to wear, foul or corrode. Light weight; In the AR, ready availability of standard parts at extremely competitive prices; Direct impingement cons: Less insensitive to ammo variations.

Examining Gas Operating Systems: Direct Impingement vs.

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. The Direct Impingement AR. Direct impingement is the original design of the AR15.

Well, how about adding adjustability to the AR’s direct impingement (DI) gas system. Being able to adjust the AR’s gas pressure will allow one to tune the rifle to proper pressures when running suppressed. Plus, it’ll also address the issue of increased pressure from gas port erosion.

The gas channel carrier rail 120 contains a main gas channel 122 disposed between an inlet end 124 an outlet end 126. Rifles like the battle-proven FN FAL and the HK416 have adjustable gas capability, so why not a DGI (Direct Gas Impingement) AR? Adjustable gas on rifles is nothing new. The battle-proven classic FN FAL has always had the capability to change gas pressures.
