At the end of the day, direct impingement and gas piston operating systems both have their pros and cons. If you aren’t sure which you would prefer, you can try a few different types out at our shooting range . DIRECT IMPINGEMENT - The advantage of the DI system is that it is simple, lower cost, and does not require the precision setup for reliable operation that the piston systems does.

The direct gas impingement operating system has a gas block fitted to a barrel having a bore, the gas block in communication with the bore. A gas sleeve is located in the gas block, the gas sleeve in communication with the bore through the gas block. A bolt assembly having an impingement cylinder and a gas line 2015-04-06 2005-04-03 In our last two posts, we studied gas operated actions based upon pistons: the short-stroke piston action and the long-stroke piston action.Now we will study another modern gas-operated action, the direct impingement action.This action was originally invented in 1901, but the first successful rifle to use this action was the French MAS-40, which was commissioned in 1940. This article is not a direct impingement vs.

What is Direct Impingement and How Does it Work? The first AR operating system introduced over a half-century ago, is known as direct impingement, and delivers the needed amount of gas to cycle the action. This system works by directing gas through a cavity in the barrel, which is then pushed through a thin tube where it impacts the bolt carrier. 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. Direct Impingement is the original technology, devised by Eugene Stoner. Propellant gas is bled through a small hole located in the barrel, which is then channeled through a very small tube where it can proceed to directly contact (or impinge) the bolt carrier mechanism. Therefore direct impingement gas system results in a dirtier rifle. Still, direct impingement rifles are generally more accurate than their piston counterparts.

With only two working parts this is a pretty simple design for anyone to understand.

With the gas impingement system, gas is diverted from the barrel through a tube and back into the upper receiver to operate the action. Direct Impingement is a method of operation that uses the expanding gasses from the fired bullet to continue the cycle of operations. As the gasses travel down the barrel, they are directed through a small hole at the top of the barrel. This hole is connected to a tube that travels over the … Direct impingement pros: Free floated barrels are practical; the gas tube is the only, very minor exception to floating free. Simple construction, inexpensive, nothing to wear, foul or corrode.

Stoner selected a gas operating system to help make the AR10 (and later the AR15) lighter than the piston operated M1 Garand and M14 that preceded these rifles.
