Air Venturi Avenge-X PCP Tuning Guide, AEAC Pre-video Learning
- Thread starter Airgun Nation
- Start date
I've been wondering about the avenger X 22.. so my question is.. say that you tune it for the heaviest slugs that will fit the magazine.. to around 900+ fps with the port setting on high.. and then switch the port setting to low what will it do then with say 14grain crossman premier round nose.. I'm not really into tuning, pretty much just shoot out of the box as factory so I don't know if this is a way to have a gun shoot the heavy slugs and still be able to plink with cheap ammo.. so far I have only shot crossman premier, jsb 18 and jsb redesigned heavy.. all in 22 caliber.
I'm also curious about how some of the slugs are actually lighter than the jsb redesigned.. so what is the purpose for a light slug over a heavy pellet?
thank you for any advice anyone can pass on.

Hi Mark,
I'm new to the Avenge-X, but as far as I know there is no airgun that will efficiently operator at two extremes. It is fully adjustable (reg, hammer, transfer port). Ideally you'll want to set up your airgun to shoot projectiles of similar weight. The regulator and the hammer are the primary tuning components, while the transfer port can be used for a quick change from high to low power. From my understanding transfer ports simply restrict the amount of air allowed to enter the barrel. I have not tested the effects of the TP on the Avenge-X.
It's typically best practice to tune your airgun for the projectile you intend on shooting the most. You do this via the regulator and hammer (with the TP fully open). Then you could theoretically turn the TP to low to shoot a lighter projectile or lower power. But keep in mind that the efficiency is based on the regulator and hammer.
Diablo shaped pellets typically yield the best results under 900 fps. With the exception of the .22 cal 25g MRD's that usually like to fly a bit hotter 930-980 fps (depending on the barrel). Slugs typically like being shot 950-1050 fps. At that speed slugs typically deliver a better BC than a diablo pellet.

any one give an opinion on the Avenge-X .25 or the niksan Ozark - TS ? supposedly looks like kral and niksan are made in the same factory i do know the niksan is not regulated im on the fence ready to order 1 or the other but with the niksan being so new i cannot find any reviews on the .25 cal only .22 and no one is really doing any head to head comparisions . im leaning towards the avenge-x BUT i want to make sure i do my research esp with the niksan being 535$ atm on donnyFL 5$ over the avenge-x . the only person i could get a awnser from on this was a youtuber mentioned the avenge-x being more tunable .

thank you for the concise and thorough answer.. although you did hint that it could be tuned for the heavy slugs and still be turned down for lighter ammo although I understand that wouldn't be ideal for the lighter ammo, it might keep it from going supersonic??
I am not familiar with the abbreviation you used.. 22 caliber 25g MRD's.. could you please let me know what that is? I know that my jsb redesigned heavy shoots and hits really hard.. but it also for some reason makes my blitz 22 into a bolt action. it shoots well in my American tactical liberty nova 22 which is pretty close in design to the avenger X without the gauge for regulator ... also it makes the umarex notos pistol hit very hard and a lot quieter..
I've got a air leak on the american tactical liberty nova.. it's very slow.. takes a week to drop 1000 PSI and it always quits leaking at regulator pressure 2000 PSI.. I'm figuring that if it was valve or tank area it would go empty.. and so the only place I can think of is the regulator atmosphere vent..
I got it from AOA 8? years ago and the company is out of business and AOA doesn't work on them.. Captain O ring has o ring kits but other than that it appears that parts might not be available
I really like the gun so I hope I can keep it going..Mark

I performed this test already with my new Avenge-X .22 cal with the TP set to high tuned to shot the JSB 18 grains pellets between 870 and 880 fps (I don’t shot with slugs). Then with this same tune without touching anything else set his TP to low and shot a string of 10 rounds with the lighter crosman premier 14 grains pellets and this were the results. If you’re curious about the weather still been in the mid 80 degrees at this time of the year, I live in the Caribbean PR not in the states.

Bought a tube synthetic Avenge-x and having a great time.
Find myself wishing that I'd bought the bottle though. Don't see any upgrade kits. Are those out yet?

I pulled some (actually quite a few) patches through the barrel with a Patchworm. It was dirtier than I expected. The manufacturer must’ve put some anti-corrosion stuff in there!
I put it over the chrony and it was shooting the 18g pellets a bit hotter than I like at about 920 fps. Not sure if the difference in velocity (from the 10 for 10 test) has to do with different elevation/atmospheric pressure or a clean barrel, but it was shooting 885 fps in Ohio.
I reduced the hammer as much as it would go. *it has a stop pin or something so you can’t accidentally back it out too far. Which is now giving me about 900 fps.
So I took the Avenge-X out back and sighted it in at 50y.
I tested 3 different brands of 18g pellets, and apparently this barrel like the H&N 18’s best.

No I did not. The only pellet I've ever got to shoot accurately above 900 fps is the .22 25g JSB MRD's.
The H&N 18's at 900 fps shot very well for me at 50y.
*The JTS Dead Center pellets were a very tight fit in this barrel.

Working on getting those online now actually. I hope to have everything online by the middle of next week. Lot of different kits and stocks to sort through, but almost there.

I have a rifle that I think shoots too hot, 1050 fps but it's accurate enough for me to get all shots on a 3" spinner at 50 yards.. with open sights and no glasses
so both target and sights were fuzzy and I don't like the rear peap sight because the hole is too big for me.. so I was pleased..I also shot a basketball size hornet nest down around 40 ft up from a distance, just cutting the limb off the tree.. I thought it was a good way to get rid of it and not get stung.
did you test the velocity of the jts since you said they were tight? just wondering if they were so tight that you lost a lot of velocity?

any aftermarket stuff or all run of the mill air venturi stuff? i cannot wait for people to start making custom parts for the X

I did this 10 shots string with my Avenge-X in .22 cal with the JSB 18 grain’s pellets with the h/s all the way to the left (0 tension) with the reg set to 100 bar that was the lowest psi I could get.

What is the chance of a .30 barrel being made available? I think I remember hearing something about this in one of the Shot Show videos but haven't been able to find it again.

Not on the X platform. It's possible in the aftermarket but modifications to the breech itself would need to be made to accommodate a .30 cal safely.
