I recently was bequeathed a few used airguns. Slowly trying to learn about each. What's y'all'ses thoughts on the Crossman Incursion Nitro Piston? For that matter, what is a nitro piston?
Thanks!

"How Does the Nitro Piston Technology Work?
A nitro-piston air rifle’s charging mechanism consists of a nitrogen-filled piston that is compressed when the barrel is cocked. The nitrogen in the piston is already compressed but is compressed even further, holding immense pressure once the ammunition is loaded and the barrel is locked straight. When the trigger is pulled, the nitro-piston is released and pushes forward, generating the energy that propels the ammunition down the barrel."Found that on the net. I can't comment on that particular gun as I've never handled one.

My ruger is a gas piston.
I'm still not sure which I like more; the springs or the gas filled
The gas rams are a bit less loud mechanically than the springs.

It looks like one of the standard Crosman/Benjamin Nitro piston guns. They often have good barrels but horrible heavy triggers. There are mods and aftermarket triggers for them which will improve the trigger pull. I had an early variant-it shot well for a while, then the breech lockup got flabby due to the plastic breech washers wearing out. I replaced them with brass washers, but it was never accurate again. Mine might have just have been a dud, give it a try with different pellets and see what happens.
To answer your question-a nitro piston is a gas filled strut similar to the ones that hold up car hoods and camper shell doors. The gas is compressed by a piston in the strut as the gun is cocked. The compressed gas in the strut acts as a spring when the gun is fired.

My friend had bad luck with Crosmans' NP system in their F4 break barrel. He bought the gun second hand and soon noticed, that the gun had a little bent pivot pin on the breech, which is in my opinion because the gun had a really hard cocking cycle and the torque must've caused that. So then he just replaced the gas-piston system with a simple mainspring and also had to modify the existing piston a little bit, in order to support the spring... called it a day after that. The gun has a much smoother cocking cycle now, with much less torque.
I should also add that whoever has a NP system in their Crosman, should have all of the moving parts on the gun well lubriacted in order to prevent wear and tear, as well as material deformation (on the lever especially).

True that about the noise levels, the pistons are quiter and have a little less recoil (probably due to their heavier weight), and are also more easy going on the scopes - scopes last longer on gas-piston driven guns. However, the thing is that the piston guns are a little bit jerkier than actual springers, because the gas-rams actuate and send the piston into bottom of the cylinder at about 20-25% faster rate than the mainsprings do.My ruger is a gas piston.

Thanks for the information everybody! As an airgun newbie, I really appreciate these explanations.

The big difference is that you can leave a nitro cocked for an extended period without worry of fatigue on the spring.
