Nitro Pistons.

"How long do these Nitro Pistons last?" Dunno, I have owned one Nitro Spring from my Vantage NP and it has lived in three different guns, and had thousands of shot cycles with no sign of weakening over the last three years. This from a Nitro Spring that for the first year or so of ownership had a bent cocking shoe shaving aluminum off the outside f it every time it was cocked.
"Are they replaceable?" Yes, but it will require a decent spring compressor. They cost about $25.00 from Crosman. Welcome to the "NP fold!" I really like this power plant. They're powerful (enough, though I wouldn't use one in any caliber larger than .22), tough, and fairly maintenance free. I wish Crosman put decent triggers and improved quality control on these guns. Then they would go from being perceived as "economy" and "starter" guns to truly top-notch equipment.

I have an NPXL .25 that could go from my cabinet to yours...

I read somewhere that nitro pistons are rated at around 10,000 shots. Seems like a lot, but only 20 tins of 500. Then again, that's a lot of exercise cocking the gun!

10K shots should be enough to keep anyone shooting for several years.

Until you get sick of their poor quality and trade them for something better.

A "NITRO" piston is nothing more than a NITROgen gas charged strut (spring) just like the lift struts that open the hatchbacks on cars. They don't have the built in resistance so they go fast instead of slow. So they should last a good long while. Average life on those is about 7 years. The gas will eventually seep out even if unused. I read that on one of the manufacturers site's a couple years ago.

The wear point probably isn't the piston itself, but the teflon guides that reduce friction (at least in the Crosman design). The guides keep the piston from rubbing against the barrel. The will wear over time, so having used teflon stuff in other applications, I think that's the real wear point. If a Crosman designer is out there and knows better, please let us know.

The Crosman NP2's had a terrible quality run at first. Welds didn't hold, sights fell off, and the rest. I think the overall technology is OK, but execution and quality is a must. Perhaps, these are really being sold with them being a "Disposable" gun in mind. In 5 years when the guides wear and the pistons leak out, just toss the gun into the dumpster and get another. Hope that's not the case, but who knows?

Man thanks for bringing this up I just bought one and was wondering that to.

I just purchased a Benjamin Steel Eagle {Jim Shockey Signature Series} Nitro Piston 2 rifle in .22 caliber. I took it out of the box, and immediately noticed that the muzzle end of the barrel was flared/mushroomed out. Then, I shouldered the rifle and noticed the scope mount was not welded onto the receiver properly. The scope base was welded way off to the right of center. Talk about being disgusted ! When I called Crosman, the female customer service rep told me that I would have to send the gun to them {No kidding !}. So, instead of being able to shoot my new gun, I had to ship it back to Crosman today. That's what I get for trying to buy local, their factory is just an 1 1/2 hours from where I live.

My Benjamin Trail NP XL 1100 seems fairly well made. The trigger is badly designed, but well made. The weld between the Picatinny rail and the receiver is very neat. The comb is too low, but the stock is decent. The trigger guard is plastic and one end screws into the stock instead of the receiver. The scope mounts it came with are garbage. Otherwise it's great.

My Hatsan 95 Vortex uses just air, not nitrogen, but when it works it's packs a pretty good smack. In .22 it moves 14.13gr lead at 837fps for 22fpe. However, it had a defective seal and I should be getting it back from factory repair Monday. The Quattro trigger is very nice. My last gun was a Crosman Quest 1000x and I just can't go back to those low end Crosman triggers. Took all the fun out of shooting for me. Then again the Crosman never had a defective seal, so....

Just received my replacement Steel Eagle rifle from Crosman today. Gun looks good, can't wait to try it out. Kudos to Crosman / Benjamin for the quick turn around time, but they need to do a better job on their quality control before they put a product in a box and ship it.

Just shot my Benjamin Steel Eagle .22 cal Nitro Piston 2 for the very first time. For some reason, it was key holing with RWS Superdome pellets. ... tried some Crosman HP pellets, and they worked fine. I will definitely have to tweak the trigger pull adjustment.

Last year the Benjamin trail NP2s had an issue with the scope rail falling off. One of the reviews on PA had that happen. Crosman fixed that issue in later rifles. I ordered one for one of my grandsons in December and the scope rail was welded or stuck on crooked. At 60 feet off a bench it started 11 inches left. The scope ran out of adjustment. PA said just send it back. And I used that credit to get them to send me a tx200. (well I did have to add a few dollars more)

I've had a trail np xl 1100 for some time and after a trigger change and new scope mounts and a hawke scope it does an ok job.
