Gas rams can be just as reliable as spring guns, and probably smoother since on the non strut types as in the RX series, the moving parts have to ride on synthetic seals.
Their "problems" start when people over pressurize them in an effort to get more piston speed and therefore hopefully increase the muzzle velocity of the pellet.
This results in burnt out seals, poor accuracy, broken scopes, loose screws...
Both gas ram and spring guns have a physical limit governed mainly by the size of the cylinder/stroke and transfer port, that ultimately establishes the gun's power regardless of the type of power driving the piston.
As a kid about 40 years ago, I recall seeing scuba divers with Italian gas rammed spear guns and boy could those things shoot.
So using the gas rams for propulsion, is not something new or inherently unreliable, if it is used within its design limitations and application.
