I recently stumbled someone asking what’s the difference between a short-stroke gas piston and a long-stroke gas piston, as well as long and short actions in rifles. Since long and short are both in the name, I figured we could jump in headfirst and answer the questions: read on to learn more about the long stroke piston and short stroke piston (and maybe a little about direct impingement).
2019-08-21 · The Direct Impingement (DI) system is sensitive to deviations from the initially designed 20" barrel AR with rifle-length gas system. Piston ARs aim to remedy shortcomings when it comes to specialized ARs. Let's consider the differences, pros, and cons of DI and Piston ARs. We will refer to all types of AR-type rifles as ARs regardless of caliber.
But is that really fair? Here are Richard Mann's 6 factual observations in the AR-15 direct impingement vs. 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. 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.
Direct-impingements today make up the bulk of ARs on the market, which means there is greater parts interchangeability. Some say the gas impingement operating system “poops where it eats”. But is that really fair? Here are Richard Mann's 6 factual observations in the AR-15 direct impingement vs. 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. Click to enlarge.
In the gas operated weapons there are two main types: Piston Impingement (PI), where the gas pushes against a piston as in the AK-47 or Direct Impingement

Jan 25, 2012 In the mid-length direct impingement operating system the gas system is When a piston-powered rifle or carbine is fired, the hot gas from the
Gas Usage Direct impingement uses the gas from the fired bullet as the force that moves the bolt carrier group, completing the cycle with the extraction and chambering of the next round.
Downsides of Gas Piston. Gas piston AR-15s are heavier and have a stronger recoil.

Gas piston bolt carrier groups do not heat up as much as those in direct impingement systems. Downsides of Gas Piston.
With piston operation, gas moves down the barrel driving the bullet forward; however, instead of going into the gas block and being redirected back, the gas is directed up into a cylinder where some of that pressure is used to push a piston forward and reset the bolt carrier group. In a direct impingement system, there is no piston, piston rod or cylinder at all.

Jul 8, 2019 A regular AR-15 fires, ejects, and chambers rounds using either a direct- impingement or piston-operated gas recoil system. That's a mouthful
However, instead of being forced into a tube as it is in a direct impingement system, it is contained in a separate cylinder. Features of Direct Impingement AR 15.

Still, direct impingement rifles are generally more accurate than their piston counterparts. 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.
As with direct impingement systems, the firing process begins with high-pressure propellant gases being syphoned off through a small hole along the gun barrel. 2017-04-19 · Featured DI (Gas) System AR Upper: SIONICS Weapon Systems Patrol ZERO. Pros and Cons of DI. Direct Impingement AR Uppers tend to be lighter than the Piston AR Uppers out there. That is because DI systems have less moving parts: gas block, gas tube and that’s it. Fewer parts mean less weight. The only big difference between direct impingement and gas piston is where the gas goes after helping expel the bullet through the barrel. In a direct impingement gas system, the gas created from firing gets pushed along the barrel with the bullet until it hits the gas block.
