Help, FX Maverick won't fire

To be sure I understand:
- The cocking arm moves freely and is properly connected to the cocking rod and the rod also moves freely.
- You took the chassis off and squeezed the trigger disconnect by hand.
- The trigger disconnect moves freely, but the gun did not fire.
- There is no slug in the barrel.


If the gun is cocked, then the trigger disconnect should not move freely. It should be engaged with the sear, and break the sear when manipulated.

When the hammer spring micro adjuster is too far out (as mentioned in the last two posts), the gun won't cock at all (sear will not engage the hammer).

Are you sure the gun is cocked (sear engaged with hammer, ready to fire)? Is it possible that you expect the gun to be cocked, because you pulled the cocking arm all the way back, but in fact the gun is not cocked because of the HS adjustment is interfering with the sear? Or, are you sure the gun is truly cocked and ready to fire (with or without a slug)?

If the gun is NOT cocked, you will feel the resistance of the hammer spring when you pull back the cocking arm. If the gun IS cocked, the cocking arm with swing without resistance.
 
To pomohlo. Pro Boha!!!
Stiskl jsem spoušťový mechanismus imbusovým klíčem a puška vystřelila.
So I finally solved it! Heureka. Broken hammer spring!!! A small piece of spring prevented the shot!

wonder what broke the hammer spring?
I was wondering the same thing. After looking very closely at the last photograph and zoomed in on my 1080p monitor, the break happened right where the spring end factory "grind down" started (or ended, depending on how you think about it). In other words, the spring broke exactly at the point where the "unground" part of the spring meets the "ground" part. They grind too much too fast. They don't care about taking the temper out of the spring steel or stressing it.

Аз също колеги преминах през тази тъпа ситуация със счупване на същата пружина. При мен счупеното парче беше много по-малко, може би 1/10 от това тук, но създаде същите главооболия със невъзможността спусъка да закопчее ударника. Пружината в моя случай беше ХУМА , тунинг пружината !!! Добре че когато излизам да стрелям, подвижната работилница е в багажника и мога да реагирам мигновенно ;)

The english translation of this (via google translate) is
(Me too fellas went through this dumb situation with the same spring breaking. On mine, the broken piece was much smaller, maybe 1/10 of what it is here, but it created the same headaches with the trigger not being able to lock the striker. The spring in my case was HUMA, the tuning spring!!! It's good that when I go out to shoot, the mobile workshop is in the trunk and I can react instantly)

Maybe this broken hammer spring problem is more common than I thought. Might be a little off-topic, but I also have the huma tuning spring and I recently read posts talking about how they start out as 58mm long and soon become 56mm long with just normal use. I'm not a metallurgist, but it seems like a good spring wouldn't break or become weak so easily. I guess that'll be my next research project.

interesting, was Alfonsmucha also a huma?
 
Factory spring. The rifle is about two years old. This thing also makes the gun not cockable! I still didn't know what it was. This is the only glitch so far.
This thread is about the fx maverick not being able to be fired after being cocked. There are a lot of other threads that talk about all the reasons an fx maverick won't cock. Generally there are two things that would keep an fx maverick from being cocked. The most common reason is that the spring is completely compressed before the hammer can come back far enough to latch on to the trigger sear OR maybe the spring is not fully compressed, but the hammer weight itself is fully pressed against the spring cup and the hammer and is keeping the hammer from coming back far enough. Either of these cases means that you are trying to get more hammer spring power than the spring can provide. In this case, you might just need to use a lower 2nd regulator setting and then your spring will have enough power, but it could be that you really do need a more powerful hammer spring -- like a huma tuning spring. The second most common reason a maverick won't cock is that the cocking rod "hand" is not positioned correctly on the rod and can't move the hammer back far enough.
There are lots of threads that talk about this stuff. For an fx maverick, they will mostly be old threads, but the information is still valid.
