ATI Nova Freedom .177 "no warranty parts gun" (pic heavy)

[BigBird]

These guns are a bit different than your regular pumpers. There is a precharge chamber that needs to have 1740 - 1800 psi. If you take the small end cap cover off of the front end of the air tube you will see the fill port. You will need the small fill probe to fill it from here. This precharge air chamber assists in pumping effort for the main chamber. I have not needed to open my gun so I don't know first hand about repairing it. I'm just reporting what I have read from the .pdf files. I know these are 'no warranty' guns but the owner's manual states that guns not holding pressure in the precharge chamber should be returned for repair. You'll notice that the full priced guns do not come with the small fill probe. Being a 'no warranty' gun, you have to deal with the issues on your own.

I accidentally released the air in the front chamber and then read here somewhere where somebody here said it's okay to do that but you will have to pump more but it makes it harder to pump (maybe a couple more shots). I don't have a front fill probe and haven't been able to get time to try to make one.  So I pump a little more now.

I am probably wrong, but it was my understanding that if you release the pressure in the "pre-charge" tube, you only have to pump it up more the first time.  Then, the pre-charge tube should stay charged (~1875+psi) and *regular* pumping should go back to "normal".

As I said, I am probably wrong, but hopefully someone with more knowledge and experience than I will jump in and either confirm or correct me on this.

That would be great however there is a piston in between the two Chambers (with 2 o rings) that separates the two Chambers.  The post that I got my information from, the member here posted that he took out the piston to get more airspace.

Ah!  Well, mine was new and I have not modded it in any way other than adding my DIY PVC slip-on LDC.   I did have to degas the gun once, but I am not sure if that degases the pre-charge tube or not.  It DID take a lot more pumps to get it filled back up after degassing, but even with the hammer spring turned IN (clockwise) one full turn, as per instructions after shooting about 500 pellets, I am still at ~4 pumps per shot on high power and ~2 pumps per shot on low after the long initial pumping after degassing.

The Freedom that I've been using regularly has only dumped air 1 time and that's when I shot it way down right after I bought it.  I was just basically seeing how it was doing then testing with chrono etc.  I pumped it back up and it hasn't dumped air since, I don't shoot below 2K anyway because of the way that I have it tuned.

I think I read somewhere, that dumping may occur if you let the main pressure tube go somewhere below 2000psi, as that is about where the pre-charge tube is pressurized.

Don't hold me to that, as I am not completely sure about it nor do I remember where I read it.  So far, mine holds pressure fine and I have not had to degas the gun again.

I usually pump it up to about 3000-3200psi and never let it get below about 2200-2400psi.  That is more than enough for a 10 round mag and as soon as I get my cheap Chinese chrono, I will do some testing and maybe adjust the hammer spring a bit.  For my backyard pesting, even on low power it is plenty powerful, but I want to do some testing for longer ranges out to about 60 yards.

These two o rings were bad on my last one ...

Noob questions, are those two "number 11's" the Orings that are usually the buna 006?

[Wayne52]

Steve when I ordered the o rings for it I measured them and ordered accordingly (mm) and they were a perfect fit.  I honestly don't recall the exact size they were but I find that's the best way to order them when I need o rings.  In that assy manual that I downloaded, some of the sizes they have in that are incorrect how they have them listed, I realize that the asian's measure their o rings different however the one's in question weren't even close.  I think what happened was in haste when making the manual for these guns they got some size's switched around by the looks of it.

Ok

A dumb question but I have to ask it. I've been reading through this lengthy topic with interest and have to ask, where is everyone buying the "parts only" Freedom's and the
"no warranty" Liberty's? ATI? They don't list them on their site so I'm guessing you have to call them or email them about availability? 

Also, Is the Hard Air -20% coupon still active? I saw mention that it isn't despite the 12/2019 Exp. date listed on the coupon.

Gerard...
I'm not sure about the 20% off thing but. I don't think any discount will be offered on the no warranty guns anyhow.
To inquire or order a no warranty gun from ATI you will have to call them and ask for customer service. They are really nice folks and will be able to tell you what is available. If you purchase you should have a gun within a week. If you read through this and other threads about the no warranty guns you should know that not all of these gun come out of the box in working order and most don't come with the accessories such as, mags, fill probes, open sights and manuals. There are other sources for these items. I would guess that 95% or more of us got guns that do work with minor issues. The rest got guns that need a total rebuild or have parts missing.
Good Luck

[Wayne52]

Bill it seems like a lot of the earlier ones that people got the guns were mostly without the accessories but some of the later ones came with notes in them that actually had accessories with them, I think that a lot of them were just guns off the shelf that were used to replace missing stuff for warranty guns people already had but we'll never really know I guess.

Wayne.... I saw some that even had the issue written on the outside of the box. When I ordered what they told me was the last .177 I was really nervous that I was going to get the 'rotten apple' that had been picked over. That wasn't the case at all. I got a great functioning gun except for a small over night leak that I'm not even going to bother fixing. I got front and rear sights with mine but no mags or fill probe. I was able to source them elsewhere.

When it was first posted on HAM it wasn't working in ATI's online form.  You had to call and talk with someone in customer service to get the discount.   They fixed the online form a while ago, and should apply the 20% discount to your order.  I think it is only for Liberty's, but haven't tried it on Freedoms.   Parts guns don't get the discount.

I had forgotten just how much energy I was getting out of the box so I searched and found it on page 20 of this thread. I've since put the UTG 4-16X swat scope on it but so far this gun has worked flawlessly since I've owned it.  I did back off on the hammer spring quite a bit (1 turn) when I seen what it was doing.

here's the out of the box numbers

Wow, and I thought my Gamo Swarm had limited scope mounting space. I'm guessing any scope over 8-10" long is a no-go! So much for using any I have on hand. I'm happy to hear you've had no issues. I'm waiting to see Hajimoto's review of it. Maybe he'll have some interesting insight(s) about it.

I have a 6-24 50mm AO scope mounted on my Liberty which is almost the same receiver as the freedom. My Aspen aka freedom has a full size UTG 3-12 44mm swat side adj ao and it fits fine also. Haji reviewed the Liberty but haven't heard anything about him reviewing the freedom. Now Jim Hunter did review the Aspen.

[Wayne52]

The scope that I have on my Freedom is a UTG 4-16X swat scope with a 30mm tube, it works great for those long distance shots.

[G-man]

Yeah, I sent him a email and asked him if he was ever going to review the Freedom/Aspen since he had reviewed the Liberty.  His reply was along the lines of "funny you should ask...."  That was a few weeks ago. So I'm just waiting patiently. I know he has a lot of things he's busy with.

. I'm guessing any scope over 8-10" long is a no-go! So much for using any I have on hand.

I may have to disagree slightly.
Mine is pushed all the way forward, and is a clean sight picture for me.
