All gas springs (gas pistons, gas rams) are NOT created equal! The Nitro Piston 2 has it all over the original Nitro Piston and almost every other gas spring on the market. We've compared the original NP powerplant to the NP2 and once you see the Head to Head results you'll see why the NP2 powerplant is superior. Most gas springs have a reputation of being hard to cock, but the NP2 put an end to that. According to airgun writer Tom Gaylord, it's the easiest-cocking gas piston he's ever shot. But Crosman didn't stop the improvements there. They also improved the trigger so it feels like it's been tuned!
