Found the problem.
The cheap blue Amazon filter was leaking.
I couldn't hear it over the compressor noise
I just happen to grab it to move it over and felt the air leaking. Removed the filter and pumps up fine.
Now to find a better filter that I can afford .
So I dug into my Zelos today to check and adjust the pushing pin depth.
However, taking the top plate off I found loose screws and one stripped. Even the screw that holds the accuating rod for the push pin was about to fall out. This is all on top of the four missing buttstock screws.
Got an...
I normally tear a gun almost completely apart checking everything, cleaning lubing.
I just wanted to shoot this straight out of the box.
However, I did clean the bore very well first.
First time opening up my Zelos for trigger adjustments. Got the trigger to a crispy #2
Long first stage, but that's the way I like it.
Almost no overtravel. Adjusted trigger shoe down a bit to fit my grip better.
Very happy.
Also drilled the buttstock to access the hammer screw, so I can...
Right now I'm getting 948 fps with 18.1gr JTS pellets but only 847 fps with 23gr H&N Slugs.
I'd like to get those slugs to 900 fps.
Is this doable without losing accuracy?
And best way to achieve this?
Thanks
Short range session. Shot a couple Pinty Knightfalls. One did well, the other not so much.
Then broke out the Zelos .22
First time shooting these pellets a friend gave me. I am going to have to order more.
This rifle makes me smile 😊 .
So I have a few knockoff Airforce rifles.
The bolt has orings inside that slide over the barrel.
Silicone oil is not a good lube for this.
Put it on, work the bolt a couple times and the Silicone oil is doing nothing. Even getting it on my fingers, rub them together and it's gone.
What else...
Tried again today, no joy.
Looks like I will tear down the regulator.
Also going to pull the the hammer, check for burrs/rough spots and polish.
Anything else I should check?
Thank you,
To be honest, I have never done a deadhead check on this unit.
However, I just topped off two of my guns to 3600 psi with no issues.
I did this in the house where it is cool.
Temps here are 100*, so I'm guessing my garage is a bit hotter where the pump stopped pumping.
So for the...
Bought new 7/25/2025 off Amazon.
Very little use. Was filling one of my air rifles up
Took it to about 2000 psi
From empty this took about 7 minutes.
Then shut it down for zbout 20 minutes while I went in the house.
Then decided to go ahead and top it off to 3600
But I had the pump stop set at...
