Gas piston assault rifle-Top 20 Next-Gen Piston-Driven ARs

More reliable. These are just three advantages cited by people who prefer piston-driven rifles over direct-impingement guns. While the direct impingement system can be very reliable, there is no doubt that a lot of fouling can build up on the bolt carrier group. A growing number of companies now build piston-driven AR-style rifles. These guns use the propellant gas to operate a rod that acts as an intermediary to exert force on the bolt carrier group to cycle the weapon.

Compete with one, target shoot for fun with one, defend your home or hunt with one. In my ish years of being in the firearms industry, I cannot think of a modern sporting rifle more versatile or uniquely customizable than the AR. Prior to considering the bevy of unique MSR personalizing options, however, you have to start with a foundation: What type of operating system they should get.

While there are several types of MSR operating systems, especially considering the number of boutique makers trying to make theirs stand out from the crowd, on the AR the two main ones are direct impingement and piston-driven.

With the direct impingement system, expanding gas flows through the gas port into a gas block and then forcefully down a small gas tube running along the top of the barrel. In a direct-impingement system, gas is tapped from the barrel through a gas port, passes through a gas block and down the gas tube that runs along the top of the barrel. In a piston-driven AR, the expanding gas flows through the gas port into a piston cylinder, where the gas expands against the face of a solid piston rod.

That rod runs the length of the barrel and moves backward a short distance under gas pressure. Once the piston has moved a predetermined amount, gas bleeds out of the piston cylinder, relieving the pressure and allowing the piston to return to its original position. Both systems use gas in their respective ways to cause the bolt to unlock and the bolt carrier group to mechanically cycle and load a new round.

Is one better? The bolt-carrier group on a direct-impingement rifle has a gas key on top that mates with the gas tube. The bolt-carrier group on a piston gun has a lug on top that is struck by the piston rod. Many shooters point out the fact that the AR platform was originally designed to use the direct impingement system.

There are aftermarket parts such as modified bolt carriers and buffers, as well as gunsmithing techniques, to reduce or eliminate tilt, but the trend is to design and offer ARs that natively use pistons instead of converting.

There are both direct impingement pictured and piston-driven guns with adjustable systems for optimal performance. Piston gun pros are generally considered more reliable because they are less susceptible to variations in ammunition. In a piston gun, the piston rod bottom strikes a lug on the top of the bolt to cycle the action.

On the cons side, piston gun cons have more moving parts that can malfunction. 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. Piston systems are also not necessarily standardized, making replacement parts a possible issue. Direct impingements are generally less expensive, lighter in the fore-end and most would say more accurate than their piston-driven counterparts.

Direct impingements today make up the bulk of ARs on the market, and that means there is greater parts interchangeability. It is the longest-serving service rifle design in U. Though there are a lot of parts to a modern sporting rifle, there are fewer in the direct-impingement system. Direct impingements do have a downside or two. If you use a suppressor, the additional blowback caused by the suppressor exacerbates the fouling.

You can have both style uppers — one a native direct impingement and the other a native piston. They swap out with the push of two pins, and then you have the best of both worlds.

With well-made, name-brand modern sporting rifles, the difference between direct impingement and piston-driven boils down to personal preference. Demystifying the Modern Sporting Rifle. The Marvelous Modern Sporting Rifle. By Scott E. How Each Action Works With the direct impingement system, expanding gas flows through the gas port into a gas block and then forcefully down a small gas tube running along the top of the barrel.

In fact, our bodies are generally smaller as well.

However, these rifles had design issues, as "the barrel length was halved" to 10 inches, which "upset the ballistics", reducing its range and accuracy and leading "to considerable muzzle flash and blast, so that a large flash suppressor had to be fitted".

The AR's are a lot more accurate, but cant take the harsh conditions that the AK or some other rifles can. It would subsequently be used heavily by U. Visible and IR infrared lights of various manufacturers are also commonly attached using various mounting methods.

More reliable. These are just three advantages cited by people who prefer piston-driven rifles over direct-impingement guns. While the direct impingement system can be very reliable, there is no doubt that a lot of fouling can build up on the bolt carrier group. A growing number of companies now build piston-driven AR-style rifles. These guns use the propellant gas to operate a rod that acts as an intermediary to exert force on the bolt carrier group to cycle the weapon.

All excess gas is bled out of the gun well forward of the receiver. This helps keep the guns extremely clean when compared to the Stoner-type direct impingement system. There is a wide range of rifle configurations available with a piston system.
