Direct impingement is best impingement.

His power is not to be doubted.

It's called the Stoner gas system and it's fucking genius

>>32163541
Considering its been around at least 10 years before the AR series, I'm gonna say you're full of shit and/or retarded.

>>32163549
What rifle used it then

>>32163562
Hakim, Rasheed, Ljungmann, MAS.

>>32163570
Oh, so we aren't talking about the system used in ARs and its derivatives then?

I figured since op was laughing he was talking about DI in the context of ARs, which is not the same sort of action as the rifles you listed.

>>32163586
They are all direct gas impingement rifles.

>>32163590
The AR is not direct impingement in the same way as the Hakim and the others.

I don't know what else you would impinge into your bolt carrier

The Hakim is DI, the AR is not, DI just shoves the bolt-carrier (imagine a short-stroke piston without a piston) while in the AR, gas is taken into the bolt-carrier through a key, into an enclosed chamber, and it's expansion allows for it to unlock and then cycle, gas is then immediately vented out the ejection port.

>>32163131
great bait op, you've legitimately made me mad

It is a principal object of this invention to utilize the basic parts of an automatic rifle mechanism such as the bolt and bolt carrier to perform a double function. This double function consists of the bolts primary function to lock the breach against the pressure of firing, and secondarily, to act as a stationary piston to actuate the automatic rifle mechanism. The primary function of the bolt carrier is to lock and unlock the bolt by rotating it and to carry it back and forth in the receiver. The secondary function of the bolt carrier is to act as a movable cylinder to actuate the automatic rifle mechanism. By having the bolt carrier act as a movable cylinder and the bolt act as a stationary piston, the need for a conventional gas cylinder, piston and actuating rod assembly is eliminated.

...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. It is therefore still another object of this invention, to provide a rifle mechanism which is not affected by variations in the propelling charge.

A further object of this invention is to provide smoother operation and longer life of the working parts of the automatic rifle mechanism. Since, in this invention, the actuating force is transmitted directly down the center line of the barrel and the bolt mechanism to the shoulder of the shooter, all of the of]? center loads found in most other types of gas actuated Weapons are eliminated. It will therefore be obvious because of this factor that another object of this invention is to cut down on climb which occurs during automatic firing operations."

"This invention is a true expanding gas system instead of the conventional impinging gas system."
