Actually, maker claims to INCREASE reliability.
Unless you have a Class III firearm and will be firing on full auto, rate reduction is a non-issue. A big problem with piston driven ARs is carrier tilt, and you should probably seek out an anti-tilt carrier and buffer setup, first and foremost.
A hydraulic piston is also known as a servo or a motor.
There are many parts to hydraulic cylinders. The main parts are the barrel, the base, the head, the piston, the piston rod, and numerous seals. They operate using hydraulic fluid.
In most other hydraulic systems, hydraulic cylinders and pistons are connected through valves to a pump supplying high-pressure oil.The brakes in your car are a good example of a basic piston-driven hydraulic system. When you depress the brake pedal in your car, it is pushing on the piston in the brake's master cylinder. Four slave pistons, one at each wheel, actuate to press the brake pads against the brake rotor to stop the car.

Hydraulic lifts utilize a hydraulic piston or ram, typically oil filled, to supply the lifting force for raising or lowering an object/load. These hydraulic systems are usually subdivided by the initial force that drives the hydraulic pump which supplies pressure for the piston. Air/Hydraulics (air over hydraulics) and Electric/Hydraulics (electric over hydraulics) are the two most popular types of power supplies for hydraulic driven systems. Cables and pulleys are often incorporated in hydraulic systems to provide equalization between multiple hydraulic cylinders that must work in unison and to remotely transfer the lifting force to areas where a large cylinder would be impractical to locate.
Mechanical pressure from the primary piston
Mechanical pressure from the primary piston
both, if it pumps liquid then it's hydraulic, if it pumps gas it is pneumatic
Check the hydraulic fluid. Hydraulic cylinder piston rubber washers to replace.
You get the force exerted by a hydraulic piston by taking the pressure times the surface area of the piston.
You need a hydraulic press to press the pin into the piston and through the connecting rod
