I bought the Hatsan AT44-10 tactical canadian under 500 fps version (first mistake).
Got to a pit to test it and I was SOOO disapointed. I could litteraly see the pellet all the way up to the can. Total lack of power. Unacceptable!
So I contacted Hatsan's customer service (second mistake) and tried to b.s. them a little bit about a "broken valve pin" that needed replacement. I tried to do this in the hope they would send me the US version of this pin which would make the gun shoot 800-900fps.
They took a week to answer
and I felt like the Alphabet org investigated on me...
Turned out they don't send replacement parts to customers. They don't even have a shop in my country who can take care of the warranties
My warranty would have been voided anyway because I opened the gun so I would have to pay for
service AND shipping to USA ? Not a chance !
So I decided to do this myself and asked a friend of mine (tird mistake) who is a machinist to scrape juuuuuuuust a little bit of metal off the pin so the air would pass better...
OF COURSE he had to break the pin... I was screwed.
I spend around 2 months looking EVERYWHERE for parts (4th mistake). They're not so common in the whole north and south Americas, a bit more popular in Europe but there wasn't a freaking store who would ship to Canada ! My own airgun dealer wasn't able to get parts from them, not even o-rings.
After a while I started searching for pictures of the pin instead of words. That's when I found that russian website which I had to translate and e-mail to in their language.
They DID ship to Canada so I ordered a s#!tload of o-rings, springs and two samples of every version of that pin.
During these 2 months searching like a fool I did learn alot about the model and mods done to it so I was more than ready !
I opened the gun and did the following mods :
- Change the valve pin from Canada to US version. Started between 300-400 fps, ended up with a decent 700-900fps.
- FINALLY succeded in removing that anti-tamper hallen screw and replaced it with a normal screw ( i now it's not really a mod but you'll know when you see one)
- I used a power tool's drill bit and soldered it on the power ajustment screw. Now I can ajust the hammer spring without having to dismantle the gun each time.
(See attached picture)
(Found out during that operation that the power adjustment screw had been stripped by the manifacturer and they done succeded to bring it ALL THE WAY DOWN the hole...
It was jammed there
so I had to repair the treads all along that part where it goes
)
- Cut off the automatic security mechanism, before that you would have to push it back at every shot. Now I decide when it's on and off.
I did not mess with the valve yet but will eventually get to it in order to save some air and stabilise accuracy.
Now the gun has become something I like but
NO-THANKS to Hatsan.
If you're not the type of guy who likes to take risks or don't have any manual skills I would say; stay away from Hatsan.
BTW it's not the first hatsan gun that gave me headache. I had two in my life and 100% had to mod the crap out of them both.
