How does a piston-driven gun work?
In a piston gun, the piston rod (bottom) strikes a lug on the top of the bolt to cycle the action. They generally cost more money, and because they use a solid piston rod instead of a hollow tube, are heavier in the fore-end. Some argue that the movement of the piston makes these MSRs inherently less accurate.
Is piston-driven AR better?
Direct impingement ARs tend to be more accurate at a more affordable price while being easier to carry. On the other hand, piston-driven systems offer more reliability, while running cleaner and cooler. Ultimately, it’s up to you to decide.
Is a piston AR-15 worth it?
Piston uppers will beat up parts faster. They DO NOT shoot well. No matter how well tuned they are, they will ALWAYS have more recoil than a DI build. A piston system is probably better than direct impingement (its debatable) but I’d doubt if it was $5–700 better.
Are piston-driven AR less accurate?
Using the same Krieger barrel, lower and upper, the Gas Piston gun upset the barrel harmonics enough to degrade accuracy for a match gun intended for 1/2 MOA accuracy on paper targets.
Why is piston-driven AR-15?
Piston-driven guns run cleaner and cooler than a standard direct impingement (DI) system, making them a big draw for high volume shooters such as those who shoot competitively like in 3-Gun. I’ve used all of them…but first let’s go over why you’d even want a piston AR in the first place.
Do piston ARs have less recoil?
Whether it’s a gas tube or a gas piston, both enter the upper receiver and engage the top of the bolt carrier. Finally, with everything else being equal, gas-piston ARs seem to have slightly more recoil than identical direct impingement ARs.

What is the difference between gas piston and direct impingement?
The difference is that a gas piston system works by forcing gas into a separate cylinder rather than using a gas tube. This cylinder contains a piston and the gas pushes this piston back, which then pushes the bolt carrier. This is in contrast to direct impingement where the bolt carrier is moved directly by the gas.
