This video really needs clarification or to be updated. The newer AT44s have an opening in the back so that you can access the adjustment with a 4 mm extended allen key without taking it apart. Also the hammer will rotate when you go to turn the key. The hammer has a hole in it that can be accessed through another opening underneath the rifle. De cock the rifle. You will need to rotate the hammer with the 4mm allen key in order to orient the hole vertically so it can be accessed. Insert a small pin or allen key through the opening into the hole to stop it from rotating. Then you can then rotate the adjuster from the back.
Great video(s)! In my at44-10s I have to use another allen key (or any tool of right size really) to hold the hammer in place to adjust the spring tension. There is a small hole near the middle stock screw in the hammer housing to do that. Otherwise the hammer would just turn along with the hammer spring screw as you try to adjust it alas no power change. I've modified the stock so that I don't even have to remove it to change my power. Great gun to work with.
Hey there, how much is it possible to adjust the power? How much up and how much down? What results did you achieve with the different power settings ? Would an regulator be a better choice for adjusting the power? :)
Can you tell me were you got the gun tray rest from... ?.. Many thanks will sefo purchase one have you got a link.. great show n video many thanks from England. 💯👍💯
Hello Rick, I just got me a 2017 AT44 Long .25 cal. Even when pulling the side lever all the way back, I still can't engage the spring tension allen screw. My allen wrenches look like the same size as yours. In addition, people on here talk about holding the hammer in place with an allen wrench or small screwdriver inserted in the hole by the stock screw. I can not engage anything to hold in place. Did Hatsan change the design of their guns slightly?? Thank you for the videos.
I see this is an older video, however I attempted to adjust power in my AT44S10 long . That 4mm allen screw will not turn either way... I did buy it as a refurb , so maybe that has something to do with it? But It is plenty powerful enough as it is so I am fine with it...I think someone may have locktighted it with the high strength red...
+Brian Mengoa - I like to see about 850 with the 15.89 grain JSBs.. but that's me. You can get a lot more out of it, you just get fewer shots. Each gun is a little different however. Takes trial and error. Cheers, AGW
My AT44 .22 QE is getting 31 fpe using Barracuda Hunter HPs 18.12 gr at 875 fps. Does the adjustment have the range to turn the power down by 50%? Maybe 16 fpe at 650 fps?? I'm hoping to get more shots per fill and less noise.. :) Thanks.
+Biggamehunter Thomas - I use the PACT professional chrony.. I've also used the ProChronoDigital system. Just get the LED or IR light kits and you'll be fine. Cheer AGW
Rick, thanks for this great video. I am fitting a HUMA Regulator on my Hatsan AT44-10 Tactical and really need to make that crucial hammer spring adjustment. I followed your suggestion and turning the screw clockwise to decrease the power/hammer spring tension and also watched your Hatsan BT65 video as well where you suggest that turning the screw clockwise would increase power. Please help me to clarify which is the correct method for the AT44-10 for definite? Thanks once again and look forward to hear from you soon. Also emailed but yet to receive a response.
+Kamran Hye - to Decrease the power in the AT44.. you turn it CLOCKWISE just like described in the video. To Decrease the power in a BT65, you turn it COUNTERCLOCKWISE. They are opposite each other. Cheers, AGW
@@AirGunWeb Rick i just bought the AT 44 10 qes. 25, over my chrony I'm getting 740 fps with 25.39 gr jsb's .thats pitiful. Hatsan is always great at giving pretty close numbers on their guns and this one is rated at 900. I know I know ,,,there is a lot that goes into getting that number, on the new ones do I need to take stock off gun to turn power up?.
Hey Rick great video. I attempted to remove stock on my at44 .25 so that I could file slot for hammer adjustment. Problem is I was able to remove rear and front screws but middle screw has obviously been threadlocked in place. Ended up totally stripping it out. Took gun to 3 machine shops and a gun shop. No one will help me out. I've now ordered a screw extracter. Hopefully this will remove it. Is obviously designed to be removed..I don't know why it's so difficult. Also where can I get a screw replacement?
When I insert a small allen wrench through the hole in the hammer to stop my hammer from turning I am unable to turn my 4 mm hammer adjust. Really cranked hard with my hand and it just won't budge. Have installed a reg and would really like to lighten up my hammer but can't. Any ideas? I read somewhere that some of these were glued or loctited in place to prevent tampering. ???
hi rick. i have a couple of cuestions. i got a pellet jammed in my at44 and pushed it out. Doing so, i think i mest up the o rings. where do i buy a repair kit, how mucho is it and can i fix it by my self.
+Bobby Whitter - if you get a chrony and get your numbers.. then take those and the pellet to Hawke's ChairgunPro software. Plug that in and you can get a very good idea of how your gun will perform at all ranges. Energy, velocity, drop, etc. it's all there. Cheers AGW
Can anyone show me how to increase the power on a galation mk4 when I take the stock of and like a black top hat.. I have no idea how to increase power, need a bit of help please
Hi Rick, sorry for getting off topic, but I thought if I posted on an older more appropriate video of yours, my request would never be seen. I am torn between buying the Diana 350 in 22 cal. or the Weirauch 95 (beemanb r9)in 22 cal. I want a gun with very good accuracy for target, yet capable for hunting if needed. I know you are very fond of both, but if you had only one chance to buy which would it be? Thank you....Pat
+pat erhardt - Just a note.. I review all posts and respond to most. No need to post on newer ones. You can also simply email me or call me (contact data is on my website). Now to your question. I like both guns very much. The R9 has less power, but will be easier to shoot. The RWS 350 will have more power, up to 25+ fpe and will be heavier and longer, making it a bit awkward to shoot with from the shoulder. If you are only shooting rabbit and squirrel sized game, then I'd go for the R9. If you want raccoon sized game, then the RWS 350. Both are great guns they are really different and difficult to compare. Cheers AGW
hey mate, im really looking at buying ether the hatsun at44 10 long qe or the bt65 qe, which would you recommend for 30 to 100 yard rabbit hunting. Thanks! Side Note, As a .22 hunting rabbits. Also In terms of noise as, im on 9 acres of land but have neighbours ether side of me so I cant have it too loud what do you suggest would be best?
+jamese brown - in .22 I would go AT44 QE Long.. If you want to see some real consistency, get a regulator for it. Take a look at the first episode of www.airgunwebtv.com. We review that rifle and take it out hunting as well. Cheers AGW
+pootato head - You can convert the CFR, but you may rather consider simply tuning the CFR. A tuned springer will often shoot more smoothly and have less recoil than a gas ram. The best way to convert the CFR would be to get the least expensive Gamo IGT equipped airgun and swap the parts. You need a spring compressor and the right tools. In the end you'll still have 2 working guns. cheers AGW
All depends on weight of pellets plus speed,only problem when shooting at higher fps a pellet becomes unstable usually around 950 fps ,so a nice sweet spot for pellets is between 860 and 900,so if you have a heavier pellet that normally shoots at 820 increase power to sweet spot,that where you'll get foot pounds you need.
this guy is guilty of over tightening the stock screw to the point of having to drill it out :( ...so YES, use the proper size #2 Phillips head (which I did) and be VERY careful not to tighten it too much on the synthetic stock for sure.
It just blows my mind how many air gun guys brutally abuse their scopes like in this video. Step A) I'd remove the scope. You're gonna have to rezero anyways.
Does anybody know the approximate setting of the hammer, coming from the factory? I bought several of these in the pump action, and really want to increase the FPE. 15 full power shots is all I want.
Thank you for show how to adjust power of AT44. Nice
This video really needs clarification or to be updated. The newer AT44s have an opening in the back so that you can access the adjustment with a 4 mm extended allen key without taking it apart. Also the hammer will rotate when you go to turn the key. The hammer has a hole in it that can be accessed through another opening underneath the rifle. De cock the rifle. You will need to rotate the hammer with the 4mm allen key in order to orient the hole vertically so it can be accessed. Insert a small pin or allen key through the opening into the hole to stop it from rotating. Then you can then rotate the adjuster from the back.
Is " the other opening " toward the barrel end or the trigger end?
Fast Freddy does this method apply for sub 12 lb ft guns too?
Great video(s)! In my at44-10s I have to use another allen key (or any tool of right size really) to hold the hammer in place to adjust the spring tension.

can you make a video describing the process and post to TH-cam
Thanks my man. May Allah reward you with happiness for your kind heart.
Thank you for your time and effort in putting out all of the informative videos. You have been a great help to me. Keep them coming!
Wow that was fast, thank you so much for the information. It is exactly what I asked for. Thanks again.
Hey there, how much is it possible to adjust the power? How much up and how much down? What results did you achieve with the different power settings ? Would an regulator be a better choice for adjusting the power? :)
Very informative, thank you
That was just great. Thank you 😁
do you a video on adjusting the power on an FX 2000?
Hey Rick. Finally bought my AT44 QE Long .25 and was a great purchase! Question, how did/do you decock the gun??? Thx :)
Don't quit your day job.. You need to insert something (rod) to stop the hammer from turning as you screw it in or out..
Can you tell me were you got the gun tray rest from... ?.. Many thanks will sefo purchase one have you got a link.. great show n video many thanks from England.
💯👍💯
Is the bullboss identical to the AT44 on POWER adjustment?
dont you have to block the hammer before adjusting?
What was your rifles power set at ? and has your rifle got a regulator fitted ? UK

Nice explanation.
Do you know if the Hatsan Invader can be adjusted or kits to increase knockdown power for hunting game?
Thank you 👍🏼
I have the invader and I don't think its adjustable, but I've never checked. Mine is in 22 and shoots hard, the 15.89 jsb's shoot at 870 to 890 fps
Hi,
Gamo Coyote Tacticsl - would I be able to adjust the power same way as you in at-44?
Please advise
All the best to you
Can you do this on a sub 12 ft lb gun?
great video... how many fps do you think is the best for this airgun

Update? If you're talking about the o-ring inside the barrel where the pellet probe enter the barrel. The o-ring that matches the pellet probe o-rings
Na sua concepção quem eh melhor arma éh a Artemis P 15 5.5 ou a Ratsan AT 44 .10 5.5 com Válvula Reguladora e Disparadora obrigado
Hi why don't you hold the hammer in place?
Because he doesn't know what he is doing.
How low can the velocity be set on an AT44? Can it go as low as 550 fps (good for 10m indoor target practice)?
He needs to lock hammer in place with a 2mm Allen wrench near bottom mounting screw or it will continue to turn with 4 mm Allen wrench
thx again
Even if you fix the power how does the energy look after the muzzle? I mean when does it lose most its power?
+Bobby Whitter - if you get a chrony and get your numbers.. then take those and the pellet to Hawke's ChairgunPro software. Plug that in and you can get a very good idea of how your gun will perform at all ranges. Energy, velocity, drop, etc. it's all there.

what is the max power you can reach with .22 cal if you fully increase the power ? thanks
I have the Hatsan at44 QE long I'm gettin 42 foot pounds right now do you know the most foot pounds I can get from this gun
All depends on weight of pellets plus speed,only problem when shooting at higher fps a pellet becomes unstable usually around 950 fps ,so a nice sweet spot for pellets is between 860 and 900,so if you have a heavier pellet that normally shoots at 820 increase power to sweet spot,that where you'll get foot pounds you need.
Using a 4mm T wrench instead of an Allen key would be much easier.
Had I known I could do this, I would of kept mine....
Think that something is missing from this video as the anti tamper had to be drilled out before this upgrade could be done.
The world is bigger...
Can you Explain more? Where would it be at?
this guy is guilty of over tightening the stock screw to the point of having to drill it out :( ...so YES, use the proper size #2 Phillips head (which I did) and be VERY careful not to tighten it too much on the synthetic stock for sure.
