I have a newer Hatsan 95 Springer in .22 and it's velocity is well below spec. I'm getting 659 - 680 fps with 14.3 HP. Hatsan lists it at 800 fps and others are reporting 780 - 830 fps with the same ammo. I let it go past the warranty period since I didn't have a chrony until recently. Any suggestions on what I can check to find out the problem? Thank you
Hatsan Hatsan 95 under performing

- Start date
Breech seal, then the spring, then the piston seal. When I had one the spring broke first, then the piston seal went tits up. Breech seal was never a problem, but it's the easiest to check.

I've had several Hatsan 95's and they are all over the place velocity wise. Some will shoot 760+ for thousands of shots. Others won't get 650.
The springs break on the ends, the seals get cut and the breech seals are either too big or too small.
The crunching at the end of the stroke could be lots of things. But a broken spring is common. They loose a couple coils at the end and things bunch up at full cock.
Take it out of the stock and look through the slot. If the spring changes pitch or spacing at the trigger end it's a broken spring. You can usually see if it's broken without taking anything apart.
Flip over the breech seal and stuff a couple coils of dental floss under it. Make sure it's sticking up a few thousandths above the breech face.
If the spring is broken send it back to Hatsan within 1 year of purchase. Otherwise it's not worth fixing. Shipping costs half of a new rifle. They are good while they last but don't last long.
650 fps will work fine. Just shoot it until something else breaks. I've shot them down below 500 fps with a spring in 3 pieces. Just aim higher at range and try not to let it bother you. They are actually better shooters when they have less power.
They are a bit of a mess to take apart. You can probably get repair parts from Hatsan and replace the spring and seal yourself. It will cause you to cuss and throw tools around but it's do-able.

Never owned one and all the advice given seems sound. If you pull the stock ( I would) to check the spring, if it over lubed? That would slow it way down.
Not sure of t the pellet you are using but some report it likes a pellet all the way up at 5.55mm. Too small a pellet will give much lower performance On most all airguns, you exp. may differ).
IF warranty was an option (could well be within the "except-able" numbers good luck. But worth a call if you don't mind postage and/or do not want to fix it yourself.
Keep us posted.

I’ve owned and gone through many. The most common problem is damage to the piston seal when installed. The sharp burrs in receiver tube from the scope stop holes damage the seal upon installation. Common problem with all springers.

Well, not all. The LGV's, LGU's, D48-56's, or the Air Arms don't suffer from this problem, and I think the underlever Weihrauchs don't, either. There may be more.

Ya, my 95 factory seal job
The lube then all the nicks .
Looks like a rat chewed the cocking arm
But a little tlc and fresh lube did get it pretty good going
Thrn after awhile the vortex ram went flat .. ..lol oh well ..lol

Thanks for the helpful info! I don't believe the spring is broken since it was this way new. I'll check the breech seal for starters. Ty!

I gave my remaining Hatsan to a buddy. They were a hoot while they lasted. A real learning experience for sure.
I finally fell in love with the HW95 once I rebuilt it. I've got it shooting great. The 2 Cometas are proving to be excellent shooters. I'm super impressed with them. The HW97K has a new Tinbum kit and Iits shooting great. So the Hatsans have become obsolete.
It's sad to think about. They murdered a lot of shotgun shells and toy dinosaurs. I have a descanso erected at the old shooting spot in their honor decorated with broken springs and shattered trigger parts.
They will always be remembered.

When you do thr thing is the trigger assembly can fall apart ots just loose pin fotted together and can be a pain to put ot back together and keep it that way to pin it back in the gun ..lol
I used short dummy pins as seen here . Push it in as the primary one pushed out in its place
Example
Other than that the rest is pretty simple brake barrel.

The safety linkages and the bear trap crap are the big problems. It's like the linkages on a Rochester carburetor. You think you have it beat and you have to go back three steps and start again.
I used a wad of painters tape to hold all those floating pins in place. It's a freaking nightmare on some of them. They just fall out if you turn the gun over.
I knurled the ends of the 2 main pins. They walk out to the right. A chisel and a mighty blow stops that sh!t. I put a drop of hot pink nail polish on all those trigger pins and it kept them from falling out.
Dummy pins are easy when you have a pile of broken Quattro triggers. Just shake one hard and the dummy pins fly everywhere...

I have a 95 refurb with a ram thats still shooting fine but I ordered the spring conversion kit from hatasan for it last week assuming my ram will die soon. I have worked on lots of rifles but never one of these hatsans, doesn't sound like it will be a fun job from these comments.

It's really not that bad. Nothing that deep breaths and a mild sedative won't fix. They are a lot more Steampunk than other air rifles. They are quite a contraption.

The trigger falling apart was all for me its a pain to hold it together and stick it in place the put the pin through with all the holes aligned.lol.
Hence the short dummy pin to hold it as i go ..
