How to adjust the Quattro Trigger on your Hatsan Airgun

[@terrynb12]

Thank you and Hatsan for the commissioning of this how to short. Lots of information packed into a kernel of time!

[@Tres26]

Thanks for this informative vidio Rick...simple easy way to get the most out of your Hatsan Quatro trigger !!

[@jamesmarcum1364]

As always, great video Rick. Simple instructions, you made what could be a very difficult job of adjusting the trigger on my Hatsan 95 as easy as possible.

[@Ukelay13]

I wish I had watched this video before messing with the adjustments on my 125. After over adjusting the trigger it took some time to get the trigger engagement reset. I seem to remember being able to watch the engagement walk with the gun out of the stock as I adjusted it. Might help to remove the possibility of over adjustment. As always, great video Rick!

[@AirGunWeb]

Ukelay13 - Thanks for the input. I hope that this video helps people avoid over adjusting in the future. Cheers AGW

I bought a used BT65 .25 cal and the pre-owner didnt know what he was doing. The trigger had no first stage, it was just one hard but short pull against the second stage. Felt like pushing against a hard spring. After I had adjusted the trigger it felt better than the T06 on my mod 48. Light and short first stage, second stage breaks smooth without any creep whatsoever. Even a quarter turn or less on the trigger weight adjustment screw can be felt very clearly. Loving the quattro trigger so far.

Good information and video, I hope you do more videos like this, I would like to learn more about my guns and how to care for them. Thanks

[@AirGunWeb]

Joe King - Thanks for the kind words. Send a thank you to Hatsan as they commissioned the work to help support their customers. I'm glad that you liked it. Cheers AGW

[@stevenlyons1459]

Thank you for your video,especially the pcp part of it.

[@taurbaby]

Great video, the combination of the weight of my 125 sniper & the heavy pull made me miss from a standing unsupported position (using the artillery hold)..i turned out the smaller screw about 3/4 of a turn..and the middle one about the same amount and now i can level the rifle and hit things before my arm starts to fatigue. Thanks!

[@inblindmodeler8786]

Great video ! Excellent information !Thanks Frank

[@jlsoip]

Appreciate the instructional video, that's going to save me quite a headache. God save anyone who actually has to contact Hatsan customer service.

[@trevor-bd4kt]

Thanks for a great video Rick..I just got both my At44s down to 1# pull. These guns shoot so sweet they'll give u diabetes LOL.

[@peppermints666]

:D

[@leebfc1901]

Great video!! just a quick question if I may. The Hatsan 900x I have just bought, there seems to be only one small screw not the 2 larger screws. I find the trigger action a little "heavy" would this small screw adjust the tension as shown in this demo? Would appreciate your feedback. Many thanks.

[@HappyFountainPen-mf4il]

Hello is the hatsan ed have the adjustment trigger and how because its very hard to pull

[@mafatone]

WTG BIG Rick. Thanks

Hi there, I was wondering if I can order a replacement kit for my Quattro Trigger MOD .33 the trigger blade gave up on me and needed to replace it. If you do sell a parts to replace them please let me know and how to get a hold on one of them? Thanks.

[@WILDLIFECONTROLLLC]

I’ve got a question and can never get Hatsan on the phone. I have a hatsan 130 QE with the vortex system. It’s always shot fine. One day I had a groundhog I was gonna dispatch so cocked the gun but didn’t put a pellet in it. Ended up not getting a shot and at the gun in the corner, barrel pointing up. Next day I went to load a pellet and shoot it and it won’t fire and there is no tension on the cocking handle. Now when you cock it it has no tension but seems to engage something at the end of the stroke but when you pull trigger it clicks but does not release the air. Did Leaving it cocked all night break something in the trigger group? Is there a process to get it to fire? I appreciate any help.

[@AirGunWeb]

Hey there. It’s more likely that the air piston leaked out. You’ll have to have it repaired. Cheers AGW

[@daweilee1986]

My trigger moves but nothing shoots, is this normal on receiving the gun in the post?

[@AirGunWeb]

Not normal. Reach out to Hatsan. Cheers AGW

[@randyjob5769]

Is it possible to get a 135 trigger to 3lb?

[@Chevy2U]

Thanks Rick for the "Dry Fire Tip", didn't realize this could cause damage. The manual says nothing about that fact on my just purchase Hatsan 95. Hope 2 dry fires didn't harm it?

[@AirGunWeb]

Chevy2U - Hopefully 2 won't do any damage.. just don't do it anymore. Cheers! AGW

[@yaddahaysmarmalite4059]

Is it possible to over adjust the trigger in such a way that the seer won't engage when cocking?

[@pbc1951]

yes

[@JoeCanyon3rd]

Rick, thanks for making the video. I have one question. On the the springer type gun you didn't explain if you have to tighten back the first (small) screw after you have made the adjustments. Thank.

[@AirGunWeb]

JoeCanyon3rd - I'm not sure I follow you.. If you follow the instructions on the video, you should be fine. Cheers AGW

[@DJDilemma1]

Hi Rick, Im trying to find the right sized allen key for the first stage on my AT-44, but none of them seem to fit. I dont want wreck the head, or buy a new set incase i get the wrong size again. Any chance you can recall the right size?

[@AirGunWeb]

DJDilemma1 1.5mm Cheers AGW

[@TheGuitaronfire76]

Hi Rick, I just purchased a Hatsan 95 model and I don't know which tool to use for the screw behind the quattro trigger. It is very tiny and my hex wrench does not have one that small.

[@AirGunWeb]

You should have received the correct allen wrenches with your gun. Contact HatsanUSA directly for replacements: www.hatsanusa.com cheers AGW

[@pbc1951]

can you just tell us the size?

[@ryansto6076]

were are the screws on the hatsan bullboss?

[@AirGunWeb]

The access hole is near the butt-plate on the bottom, that is what the long Allen driver you received with the rifle is for. Cheers AGW

[@HannibalBurgers]

Hey Rick, I have a model 135 with a Vortex piston in .25 caliber. I did my research, and decided to take on the challenge to tame this beast of an air rifle. The cocking and firing of the gun feels very smooth out of the box, aside for a strange trigger characteristic. I have noticed that when firing the rifle, I feel some forward recoil in the trigger. Based on some forums I have looked at, it seems like other have noticed this too. Any suggestions? Thanks!

[@AirGunWeb]

Heli0sophist - does it effect how the gun fires? It may not be anything you need to be concerned with. You can always report it to HatsanUSA and see if they come back with anything on it. Let me know how it goes. Cheers, AGW

[@HannibalBurgers]

Rick, Thanks for the reply. I found that it was due to cheap pellets with uneven skirts leaving gaps when seated in the barrel. It seems like what I was feeling was violent vibration from the piston slamming forward due to lack of sufficient back pressure. I switched pellet types and the rifle feels much smoother.

[@ryansto6076]

so those are for the trigger??

[@AirGunWeb]

yes the sear is at the back of the rifle on a bullpup design the trigger blade is attached by a linkage. Cheers AGW

[@jason3064]

I can't seem to find that screw behind the trigger on my Galatian

[@AirGunWeb]

+Jason E - look behind the trigger guard.. I saw your other post regarding someone possibly using my content. I do NOT write for them. Not sure what to say about the content they are using. I guess I'll have to look into it. Cheers AGW

[@jason3064]

hey thanks for the response,found it and fixed my problem.and yeah you should check it out

[@johnwalters7415]

I have not touched my trigger at all the last time I was shooting when I went to cock it it was like it was already cocked. And will not fire

[@tripplebeards3427]

I’ve adjusted my tension spring to the point where it’s all the way out and still pulls like a mule! Crappy trigger imo. I like triggers under 2lbs. I’ll have to put a scale on my talon and test it. I bet it pulls close to 6 lbs at the lowest setting. I’ve polished and stoned dozens of triggers and removed a coil or two and have several triggers in rimfire and centerfires that will break from 1.5 to under a pound on my target guns. The springer air rifle Quattro trigger gets a thumbs down in my book. I littlerally have to “yank” this trigger Back to get it to break before and after adjustments.

[@tripplebeards3427]

Well I fixed the issue today! Only took 10 years and someone on KZbin posting how to disassemble this trigger and tips on how to lighten it. I replaced both front screws with longer ones along with a lighter tension spring from a ball point pen. My Quattro trigger brakes a crisp 20 oz now.

[@pbc1951]

You will have to remove the front screw, and replace it with a longer one..... Hatsan shipped to USA will not be able to adj way down.... Due to Sue Happy Lawers etc.... True !! Make that front screw 2 or 3 mm longer.... .020" to .030" longer... I did after googling a day and finding the truth... be careful ... go to light and will go to zero !! and barrell will snap back up !! Mine is Light now !

[@juslitor]

adjusting the middle screw in too much on a springer/vortex will lead to the gun firing even if the safety is on.

[@DougFLA123]

You say the front most screw adjusts the position of the first stage, the Bullboss/Gladius manual says the front most screw is the Trigger Pull Force Adjustment. You say the middle screw adjusts the position of the second stage, the Bullboss/Gladius manual says the middle screw is the Trigger Travel Adjustment. You say the rear most screw adjusts the overall pull weight, the Bullboss/Gladius manual says the rear most screw adjusts the Force to Pull the trigger until the end of the first stage. Take the middle screw adjust for example, how is what you say...it adjusts the position of the second stage the same as what they say...it’s the Trigger Travel Adjustment, the same thing? How is your description of the front most screw and their description of the front most screw the same?

[@AirGunWeb]

Take a look at the date of this video.. it may be that they've changed things.. or they have it wrong in the manual. I really don't have much if anything to do with Hatsan these days so I'm not sure where any of this is at. best to refer to them directly with any questions you may have. Cheers AGW

[@DougFLA123]

@@AirGunWeb My Bullboss was purchased years ago so it should be similar to you 2015 video. Is it possible that when you say the middle screw adjusts the position of the second stage it is the same as when they say...it adjusts the Trigger Travel? They seem like two different things.

[@AirGunWeb]

@@DougFLA123 - I really don't know given what their manual currently says. Really you should be talking to them about it.. but here's what I remember.. there are 3 screws. Starting from the rear of the gun and going forward - screw 1 - trigger tension, middle screw - 2nd stage engagement with the sear, i.e. how much travel you'll have till you release the sear, 3 - front most screw adjusts the position of the 1 stage travel.. obviously if you start from the front of the gun, swap 1 and 3.. you get the idea. I'll tell you that the adjustable range is TINY.. you can over adjust and leave the gun either unable to cock or in a dangerous state.. if you don't know what you are doing, you would do well to get someone to help you who has experience. Hope that helps. AirgunWeb

[@DougFLA123]

@@AirGunWeb Thank you. I have contacted HatsanUSA, but no response from them yet. Your second stage explanation helped me out a lot! Thanks again!
