Well I guess the rats are going to safe for a few days until I get my rifle fixed :( I was adjusting the trigger and I got it too light. I knew it was on the edge and had hold to the barrel but when I reached for a pellet it let loose. It didn't bend it bad but it's bad enough. Maybe the barrel can be fixed maybe not. I'm going to send it to Rick Eutsler and I may have him clean it up and go over it while it's there. On the bright side I'll probably get a better rifle out of the deal. On the down side it's a hard expensive lesson learned.
When you are messing with the Quatro trigger be careful because you can get it too light and it can cause it to let loose.
I may just have to go buy that Benjamin 392 :D

I have had this happen to barrels that were harder steel .
It can be bent back with patience by hand with the barrel removed from the airgun.
Hatsan barrels are somewhat softer than some other mfg's.
The bend is probably a true overall bend (usually what happens from a slammed shut barrel and acts like a piece of spaghetti) which can be bent back by applying incremental amounts of pressure to the center of the bend (as i said usually a complete bend) This isn't new or uncommon, just a pain in the butt.

I'm going to let Rick do what needs to be done and tune my rifle in the process. I'm sure he will send me the old barrel back if it has to be replaced. It might not be a bad thing to have an extra barrel around anyway. There's a guy that lives below me that has a metal shop. He does all kinds of work. I may have him straighten it for me.

Hair triggers are dangerous!
I was shooting a HW35E that I had adjusted to be a hair trigger. Somehow, I managed to put a pellet in the ceiling, don't think I touched the trigger but I must have bumped it. Anyhow, I made note and continued plinking ... then I put a second pellet in the ceiling! How stupid.. I was paying attention... but I continued... you guessed it? I put a third pellet in the ceiling! After that I adjusted it so it's full wig trigger again. :P
Hair triggers are dangerous!

...and hope you also learned to NEVER let go of a break barrel (under lever or side lever too) until it is cocked, loaded and back in the closed position.

No doubt about that. Like I said I had hold of the barrel but when I reached for a pellet it let loose and it got away from me. If not it would have bent a lot more than it did. In this case the gun moved as much as the barrel. I never let go of it and was hoping it wouldn't do any damage but that was too much to hope for. The best lessons are the hard ones.
I'm really lucky I didn't get pinched.

You may want to have someone else do it especially if you are timid or frightened that you may make the barrel worse.. I know I wouldn't let anyone do this for me but then again.. I build guns for a living and not everyone is as bold, tall or handsome as me. :o jk It's an easy fix and you should have it back from whoever you chose pretty quickly...

I'm not timid at all. The deal is my rifle still has 10 months left on the warranty and I want to keep it that way. That's a long time as much as I shoot. I'll send it to Rick and if he cannot fix the barrel he will send it back to me and I' get frank to fix it. The guy has the tools to build a rifle from raw materials and has built custom rifles to RV's. I believe he can handle the job.

Would one of the Lothar-walther barrels work?
I guess I'm lucky my 125 came with screws that have heads on them instead of grub screws. I have it adjusted as light as it will go and havn't had any issues with it. I wish I could get it slightly lighter, but I won't sacrifice safety to do it.
I learned with my Chinese R-1 (I think it's an R-1. I can't read Chinese.) rifle to keep a FIRM grip on the barrel with the stock tightly into my armpit. It had a non adjustable trigger, and it had a tendency to let loose on it's own and almost broke a couple of my fingers once. One time it did it after I had loaded a pellet, and it fired on it's own. After that I took it completely apart and thew the bits in the trash. It was a very dangerous gun, and I did not want it to have the chance to hurt anyone.

I don't know if one of those barrels would work or not?
If I would have had the stock in my armpit this wouldn't have happened. I had the barrel but when it let loose the stock slid and got away. I slowed it down when I tried to catch it but it was too late.
All I can say is be extra careful adjusting the Quatro trigger.

Searching through some old threads on GTA, I found several people warning about changing out trigger screws, back when the screws had heads on them on rifles imported into the USA. Now, the headless screws, that created so much controversy and got people banned, come on the rifles from the factory, without good directions on how to properly adjust them. Since people can now adjust them too light, is there anyone on GTA that tunes rifles that could post up a detailed tutorial on how to safely adjust the Quattro trigger?
-
Has anyone tried sleeving the barrel, in order to make it stiffer and less prone to bending ?

The Hatsan USA site does have detailed instructions about the Quattro trigger. If you go to the FAQ section you will find it. I'm not blaming them because I read it. I knew I had a problem when I cocked it. I don't know how to explain it but I could feel it. When I reached for a pellet it let loose and I guess I was in a awkward position and the stock slid out and got away from me. I had the barrel and caught the stock but it wasn't enough. It's just one of those things that happens.
It was my fault. Here's a link to the Hatsan USA site about the trigger.

I know that feeling, it almost feel like a double click of the sear, that is felt through the barrel.
Had this happen to my hatsan, almost lost my face too. I removed the internal spring, put it back together minus the stock. Laid the rifle on its back, on the floor in the cocked position, then put my weight on the barrel.
I did that several times, it pretty much straightened the barrel.
The only problem was, the barrel came loose, inside of the breach block.
I tried drilling and tapping the barrel through the breach block, after a bit it came loose again. Tightened it after applying red lock tite, still came loose.
This was on a hatsan 125, might be better off seeing about a complete barrel replacement.
-

Barrel bend usually at the base where the it meets the breech block. If the barrel don't bend, the stock will crack. Best way is positive control of the barrel when cocking. Easy fix if the bend is at the base.

Well you can go over all the post on barrels and you will find that I have experience on many barrels. From re barreling my own to straightening, shrouding chopping, refacing and crowning square with the bore.. Yes the shrouding I do will without a doubt strengthen the barrel with no affects on the shooting other than a POI change as you will see even installing a brake on one. I have bent many Hatsan barrels without a trigger mod but an ill adjusted trigger will for sure do it. Remember I was the one that pointed out the headless trigger adj grubs that no one thought much about. I was the one that told about the removal of the rear sights to keep the long grub screw to help hold the barrel in place.
I see no reason off the top of my head why an L&W BARREL could not be installed after proper machine work in a HATSAN. I have don it on the RWS 350 with success and I know you can spin the Hatsan barrel in the block if you are not carefull with the barrel off the gun and not pivot bolt. JMO. the barrel more than likely be salvaged. JMO

QUOTE from Hatsan :
The Quattro trigger is one of the most sophisticated airgun triggers on the market today. It is has 3 user adjustable settings via 3 adjustment screws. Starting from the front of the rifle:
The first screw, closest to the muzzle, adjusts the angle of engagement of the 1st stage travel. It is adjusted with the larger Allen wrench and is best left all the way in.
The middle screw, also adjusted with the larger Allen wrench, is used to lengthen or shorten the 2nd stage. Screwed all the way in sets the 2nd stage to the longest pull length. Backing it out, moves the 2nd stage engagement further and further back in the trigger pull, effectively shortening the final pull before the gun fires. An optimal adjustment is usually about 1 full turn out. The usable adjustment for this screw is very small. Once backed out 1 full turn, there may only be 1/2 turn of adjustment to the length of the 2nd stage. Adjust using 1/16 of a turn between 1 and 1.5 turns out. Caution! DO NOT OVER ADJUST as this could damage your gun.. Use proper caution when adjusting the middle screw.
The last screw which is set in the back of the trigger assembly adjusts the pull weight for the trigger. It is adjusted by using the small Allen wrench. Backing out this screw will lighten the pull weight. Typically, the minimum pull weight will be between 2.5 and 3 pounds when properly adjusted.CAUTION! There is a point where the trigger is as light as possible. Continuing to back out the screw will not further reduce the pull weight. It is normal for most of the adjustment screw to remain in the trigger mechanism.
Lastly, the design of the trigger blade is a little different than most guns. Pulling straight back will increase the resistance of the pull. However, pulling back and up, at about a 30 to 45 degree angle, reduces the felt trigger pull significantly. A simple adjustment to the shooter’s hold will accommodate this type of trigger design.
END QUOTE :
If those are good enough for Hatsan's with the factory headless screws, then it should be a safe means for those with the previous Quattro trigger, that have screws with heads, to replace them with headless screws and correctly adjust them themselves.
Unfortunately, it doesn't talk about how to establish a safe "starting point" for screws that have been previously miss-adjusted or removed. Without a reference point, bad things could happen easily.
Also, regarding the 1st Screw & 2nd Screw, "all the way in" doesn't exist for a HEADLESS Screw. I believe those adjustment instructions were for the previous Screws WITH HEADS and NOT for the HEADLESS Screws.
Can any of the experienced "tuner guys" ( Bob, Gene, Shadow, etc ) please review those directions and give their input ?
Thanks !

SPRINGER!!! Correct on the adjustment method and yes just depends on what trigger Hatsan put in the gun you get. Many different style QUAT.
Seen many people in the days gone by scorned for the suggestion of the TRIGGER MOD that Hatsan now gives out from the factory. And that goes with ramming a HATSAN which is being done as well.
But any trigger work can have ill results and create an unstable gun even for those that know about the mod. No 2 triggers take the mods the same. EXAMPLE: RWS T05 2 screw trigger mod set up to duplicate the T06 INSTALLED in one gun and then removed to anther with no adjustment can prevent the gun from locking the sear or even make the gun go off on its own. Same goes for the HATSAN.

Regarding people being scorned...
What's being missed, is that it was the combination of telling people to change the screws, and the lack of understanding of how the trigger works, and how to properly adjust it, and exposing novices and the uninitiated to a potentially dangerous practice that was the problem. It was akin to someone asking for a louder firecracker, and handing them a stick of dynamite and saying "good luck". The practice was and is dangerous, and this thread demonstrates the danger of improperly adjusting the Hatsan Quatro. People were not warned just because they advocated changing the trigger screws. They were warned because the change could be dangerous for those less than experienced, it bypassed a safety feature put in place by the manufacturer, hence it was not welcome in an open atmosphere where just about anyone could read it, run to the store, buy the screws, and promptly head home and knock their teeth out or worse.
The quatro is a touchy trigger design that once longer screws are installed, can VERY easily be adjusted to an unsafe setting. Far more so than triggers like the Rekord or T05-T06. Yes, any trigger can be made unsafe. With the Quatro however, it is almost TOO EASY to make it so.
After my own testing with the screw mod and completely reworking several Quatro assemblies, and seeing more than a few mentions of random trigger conditions caused by others trying the headless screws, it's pretty obvious to me WHY Hatsan initially was hesitant to ship the guns with the headless screws.
Now that Hatsan has relented and allowed some to ship with the headless screws does not mean the warnings against this mod were not reasonable or are now invalid. It simply means the condition can now exist straight out of the box, and now no one can be responsible except those trying to adjust them, rather than those advising the mod without taking into consideration the potential for possible damage and serious injury. The GTA is about safety above all else, and the trigger mod can produce an unsafe condition, hence it was not welcome. That simple.
Regarding repairing a bent barrel.
The only proper way to do it is to remove the barrel, remove the moderator, and use a straight edge and jig. You CAN stick it into the fork of a tree, clamp it in a vice and put a pipe on the end, fold the action in half and lean your weight on it, and even beat the heck out of it with a hammer if you like, and MAYBE get it close to straight again. Or you can just visit the GTA library and see how to do it without ruining anything :P

I for one am one that has always pushed the safety button here as well. I was the one as I stated the warning about the new trigger being shipped to the USA with regards to how dangerous it was. So if you are barking at me go right ahead as others have pocked fun at the trigger topic and the krytox as well. I know why they were scored. Very good that you did clear the air for others. Sorry if I took it wrong???
I always claim that just because it worked for me do not expect it to work for you and once again I post NO UNSAFE HELP and state that I do not reccomend anyone try what I do.. I do not recommend using a hammer on a barrel or even a tree. I have the tools to work the barrel and it is SAFE and the other tools are the correct tools for the job. Also if you are not equipped to work a barrel find some one that can. If you have no clue of a trigger don't mess with it. NO 2 triggers of the same make are even the same.

I'm not barking.
I chimed in because when I see references to persons being "scorned" for doing something that as we can see from threads like this very much can be dangerous, it feels important to me that the record is kept clear and the facts straight. In particular because I too was "one" who warned specifically about changing the screws and what could happen. They were not "scorned", or otherwise treated unfairly or with malice as the word seems to suggest. They were warned, and later got banned because they chose to argue about it, push buttons, and exacerbate the issue with new threads, instead of just respect the admins.
I did not say you advocated using a tree or a hammer. It was just a VERY slight bit of hyperbole (because folks have posted about doing just those things), just as was mentioned in this very thread about using body weight to bend the barrel on a folded rifle, which is also wrong.
Moot anyways, since the OP is sending the gun out, which in this case I think is probably the smartest move.
-
Thanks for clearing things up.
I was only referencing the fact of talking trigger adjustments in general. I used the word too loosely and it was just comparing now and then. Nothing on BANNING. No intent of anything. Just as you!! Trigger work even for those who are familiar with triggers can have unexpected events. Only thing is when I cried wolf on the HATSAN SCREW INTRO TO THE USA NO ONE REALLY stated concern to my warning. Besides you can bend a HATSAN barrel without a trigger malfunction. Theey have a heavy spring and you can bend the cocking rod as well.
I have respected all the moderators and to date have not been notified of crossing the line.
I am out off this.
THANKS

Paul,
This is NOT about the previous "trigger screw mod" on GTA. It is about the "factory" screws.
Since Hatsan will soon be making all of their individual parts available, here in the USA, the issue of trigger screws ( factory ) and Quattro Trigger assembly / dis-assembly / adjustment. In this situation someone might be merely replacing a worn or broken part, right up to assembling a complete Quattro Trigger assembly from parts.
This LINK is to an EXCELLENT tutorial on the dis-assembly / assembly, and SOME adjustment for the Hatsan Quattro trigger.
http://www.network54.com/Forum/79537/thread/1301669829/Hatsan+Quattro+trigger+ (http://www.network54.com/Forum/79537/thread/1301669829/Hatsan+Quattro+trigger+)
HOWEVER, it doesn't cover what to do to, in case the trigger screws have been previously mis-adjusted or removed entirely. As a result, no information on a "safe starting setup" is available for the screws themselves. Hatsan's "all the way in" is vague, since headless screws have no means to indicate that they are "all the way in".
Would you please write up something on how to correctly do the "initial setup" for the trigger screws, so that a safe starting point is clearly demonstrated for people do this themselves ? Since you said you have quite a bit of experience with the Quattro trigger, this would be a great help to airgunners and their safety.
Thanks !

Well I guess the rats are going to safe for a few days until I get my rifle fixed :( I was adjusting the trigger and I got it too light. I knew it was on the edge and had hold to the barrel but when I reached for a pellet it let loose. It didn't bend it bad but it's bad enough. Maybe the barrel can be fixed maybe not. I'm going to send it to Rick Eutsler and I may have him clean it up and go over it while it's there. On the bright side I'll probably get a better rifle out of the deal. On the down side it's a hard expensive lesson learned.
When you are messing with the Quatro trigger be careful because you can get it too light and it can cause it to let loose.
I may just have to go buy that Benjamin 392 :D

Very simple and perfect.
I like it and in the future I may just make one for myself just to tweak a barrel.
I'm getting mine fixed because I don't have the time to mess with it and I want to keep the warranty intact. Life is just way to busy for me now. I use to deer hunt all the time but I gave it up along with a lot of other stuff for the almighty dollar and getting my kids through college. I still have some work to do but there will come a day? I suspect you may be a carpenter like me or a wood worker of some kind? That's a perfect jig for what you are using it for of a major screw up like I had.
