Fx impact MK2

[spyde82]

i have some problems with my impact mk2, it has a ES of 60fps over the chronograph and it effects my poi, i have tryed almost every tuning combination i could think of, i think it is the regulator, so i took it out and cleaned it and relubed it and it diddent do any thing.

i have checked that the reg, hammerspring, and valve dont move when shooting, the reg pressure are also stable.

do you guys have any ideas?



when i bought it i had to send it back becouse of the extreame spread and groups, it also had the old type gauges and a 500mm barrel and not the 600mm the the .22 mk2 should have, so i am not happy with sending it back one more time.



another thing i noticed was my serial number is 180819, do that mean that its not the AMP regulator?









…Generation 3 Impact X's (after Serial Number 183534) have the long (16mm) piston and large (10mm) housing (These are called AMP regulators)

Generation 2 Crowns (after Serial Number 180760) had the long (16mm) piston and the large (10mm) housing (These are called AMP regulators)…

The AMP regulators are able to be adjusted down without releasing pressure, but it is still recommended to fire at least 1 shot every 1/4 turn while adjusting down, to ensure nothing goes wrong.

Sorry to hear of your issues spyde82. I like FX and have an Impact X .25 700mm. In the beginning I experienced a few hiccups that I got through. However, I have been saying that FX need to stop working on new models and step up on the Quality Control of their existing ones, especially the IMPACT which is not cheap. Check the guns before giving the stamp of approval. Your business depends on guys like us.

 

[spyde82]

Yes i am starting to think so to, and this is acturally my second impact that is defect.



an this one my dealer won´t cover on warranty, they said that a 1” group on 25y is acceptable (WTF)

i can`t even sight it in becouse of the poi shift.

No way would I accept a 1" group at 25 yards acceptable on a $2,000.+ gun. Maybe on a $200. gun. If you dealer won't cover the problem I would contact FX USA directly and talk to them. I'm sure they would not find a 60fps drift acceptable either. Good Luck

60fps spread is a lot. My impact 25 cal does have up to 30-40 fps spread on the reg. Idk how the heck people claim their impact have like 5-10 fps spread. Or they lying. Usually 20 fps spread is acceptable. Any more and you will have poi shift at long range. I kept my gun just cause I didn't want to deal or bother getting return number and have to pay shipping back. And it wasn't a big deal like the gun is broken. But even 30-40 fps spread I wasn't too happy since I spend $2000 on it.

According to your serial number, it should not be a mk2 you have.

What did you actually lube? Lubing hammer is not advisable. Also have you checked how it is tuned? Like what is the max speed in relation to the speed of the pellet? You can not always count on the gauges when tuning as they are not always as accurate, so use the chrony numbers as reference. If you follow the FX tuning method, you should normaly end up with good chrony numbers. https://www.youtube.com/watch?v=9K9uG2KOPt0

Yes i have watch all the videos. I can easely get it to shoot hole on hole on 50m but after a couple of shots it is all over the place again. Every time i sight in my scope then it is of again and i can start over. It was then i notest the ES on my chronograph. today was a good day only ES of 38fps in 10 shot strain I have shoot around 1500 shots now with the same result.

no i did not lubricate the hammer, i just cleaned the washers on the regulator and inspected for any thing that could throug if of.

You will only get low es FPS spread if you sorted pellets or shoot slugs. Tuning the gun over a chrony by closing the adjustment valve little at time will get you to those low es FPS spread.

 

[spyde82]

Maybe so but non of my other fx guns has any problems with es fps using pellets out of the box.



and jsb exact heavy diablos is userly pretty concistence in weight and shape

[heavy-impact]

That is not the serial number. The serial number is located on the rear block under the words FX airguns.

 

[spyde82]

I am pretty sure that ernest rowe talkes about this in one of his videos and say that this number under the triggerguard is showing the model.

 

[spyde82]

i am sorry you are right about the serial number. So now i just have to figure out why the ES in fps

Replace the C3 bumper with a 1.5mm delrin washer. Wait at least 5 seconds between shots.

 

[spyde82]

I thougt about that too, it worth a try.

you know where i can get one?

Email FX and request the new gauges that are supposed to be on your MKII and a couple of delrin washers. Tell them you have an unhelpful dealer and link to this thread.

Does he have a shop in Denmark now ?

 

[tor47]

The easiest thing to try first as already mentioned, is to turn in the valve adjuster until velocity start to drop a litle. That normaly should thight up the ES.
