American Air Arms All Things EVOL - Master Thread

[pnwairgunner]

No luck yesterday evening. Torrential rain then noisy dripping woods. Saw one squirrel but he had his chicken suit on and quickly retreated up the tree. The gun was a pleasure to carry. My bottle guns have to be carried muzzle down when I have a shoulder strap on them. The Mini hangs on my shoulder like a gun should, muzzle up. The bad thing is because of the ambidextrous safety, most times when I took the gun off my shoulder, the safety was off. I need to figure out how to stop that from happening.

I haven’t had any issues with my safety getting flicked off accident on the full size Evol while I’m using a sling. I’ve carried it muzzle up, muzzle down and across my chest. That’s interesting.
I’m waiting and watching for the mini .30 to be available. Your .22 looks like a great woods gun.

I just tried to take the hex screw out of the safety knob on the left side of the gun. Was hoping just to eliminate that knob. The hex screw is tiny and my wrench is flexing big time. Don’t feel like risking a stripped head so it looks like the knob stays. Built like a tank. Everything tightened like a tank.

Push harder. It has to come out to remove the action from the chassis which is needed to do pretty much anything.

If you wanted to eliminate one safety knob, I suppose you could replace one with a nut that rides inside the receiver. I'm not sure what the threads are though. I was thinking about doing this when I was going to change out a pistol grip with a large thumb rest on the right side where the knob would get in the way.

Intersting. I hadn’t considered that.

Has anyone tuned the Paradigm to shoot 18gr pellets, I'd like to know your reg setting

Yes. I had my regulator down around 180bar I believe. Once I get my parts back from Tom I can air up and let you know. But at 50 yards they were producing a single ragged hole.

That's high, mine is sitting at 1600 psi and 940 with 18gr

When I had a 15" I tuned to 1600psi which I tuned to 870fps with the 18gr I believe.

@Vetmx Not sure if the safety has changed, but on mine I need two hex wrenches - one to hold one end stiff, and the other to turn and unscrew the bolt. Is yours similar?

I will check it out right now. I want that knob gone. With a trigger that light and a barrel that short, I don’t want a gun off safety that close to my noggin unknowingly.

 

[RicL]

Is there a time frame for when the new Evols with external regulators come out? I should probably get to thinning the heard now so that I may be ready.

 

[Vetmx]

Thanks Ezana, I’m in business now.

That was where Tom mentioned to put it. So that's what I did. It worked great, though I do want to play with it by turning it down to see what happens.

My Evol has been sitting for months. I took it out a few weeks ago to wipe it down and noticed both manometers on zero.

I figure that it may be time for a reseal, but I have no idea where the air leaked out. So I attempted to refill the reservoir before tearing it down. I couldn’t get it to take any air. I cocked it before opening my SCBA tank valve and air escaped from the barrel. I decocked it and it had the same effect. What type of failure causes this?

 

[woogie_man]

I had issues with the seal behind the foster fitting.

Though a reseal is quick and fairly easy. Just take it slow with the unthreading.

 

[orangeokie]

There are some comments somewhere from Tom about the foster fitting leaking and he recommends silicone grease/oil is the fix. Can't remember the details. I wonder if it is buried somewhere in these 22 pages of text?

American Air Arms Evol leak

Other then bench shooting to zero my Evol it hasn’t seen or cycled many pellets. I took it out last night to deal with a coyote and discovered it had lost all its air - I keep it charged to 2300 psi to be ready for predators. The leak is near the fill port but seems to be coming from the...

Does your hammer and spring slide back and forth when the gun is not cocked? Just want to double check

My hps had that issue on its first air up.

 

[Dairyboy]

I've had it come out the barrel and what I've done is close the side lever and plug you finger over the end of the moderator. Obviously make sure it's unloaded and all the safety stuff. I'm not sure it was my evol but have had it for sure on a different gun. But think my evol once also after a tear down.

 

[Vetmx]

Yeah, if you have a poppet that is being bull headed and lets air escape out the barrel even when cocked, just chamber a pellet and try to fill it again. I would be shocked if your poppet caused the leak down. But you should air it back up to check for obvious leaks.

 

[Dairyboy]

I had a leak around my gauge before which was one of the first Evols out and was common on the first ones. Tom has since changed that along time ago. I've heard the oring from the check valve on the foster fitting going out. Other than that could just be an oring on the tube?? I doubt it'd be a poppet problem also.

When we fill high pressure air too quickly this o-ring gets burnished and hard on the outside so it doesn't seal well. I put a small drop of silicone oil in the fill port hole to keep it lubed, and this seems to help sealing.

For re-filling a stubborn poppet leaker something I do while sealing the barrel with my thumb is bumping the end of the butt stock on the counter or floor hard enough to jar the poppet onto its seat.
