Piston AR 15 System: The Functionalities
The need for AR piston-system rifles were unnecessary – or to quote the words of the late Cololen Jeff Cooper – “An original solution to a non-existent problem.” Nevertheless, some manufacturers that are ruthless for perfection released a line of piston-driven receivers that appear to be the model blend of AK reliability with AR ergonomics.
With the standard unswerving impingement system (DI), gas is deflected from the barrel via a tube and back into the upper receiver to achieve the cycling. However, it can build up a lot of fouling on the bolt carrier group. This residue can give way to many malfunctions.
Besides all of that, the piston systems makes use of a piston drive rod instead of a gas tube. The rod stands in as an intermediary to apply force on the bolt carrier group to cycle the weapons. Instead of migrating through a tube, the propellant gas simply shoves the piston and then escapes out of the gas block well onward of the receiver.
As there is almost no gas running back into the upper receiver, this piston system preserves the gun tremendously clean and cooler than Stoner’s direct impingement system.

Besides that, it is also designed to be compatible with almost all of the AR-15 rifles in the market but do check the specifications before purchasing to ensure the compatibility.

Also, it works with carbine length gas systems so you could be ensured with the ease of use.
Is swapping to a gas piston upper worth it?
This is a bit of a subjective area. Piston-based uppers are an excellent upgrade over direct-impingement guns in general, however, they have a few cons as well. For a start, they are most obviously expensive. At the same time, it is also a lot more difficult to find parts for a piston-based upper, and many uppers need proprietary parts, so it might not be the best gun for Armageddon either.
Basically, it means that if something shatters, you are going to be stuck buying out of budget parts from the manufacturer, instead of a generic or OEM $20 gas block you can get anywhere else in America. By the end of the day, you will have to decide if a piston-drive AR-15 upper is worth your time and money.
