I’ve searched all over this thread and via Google with no definitive answer. So I’ll post it up here now to the hive mind. Shoot me a link in case I did miss a post or thread.
Can the .22 HPS Evol achieve 50 fpe and a high shot count? Its only 3” inches more than the 15”. However on AAA website it indicates 36 shot count. Id imagine you could do this. Either way I’m thinking of adding a .22 HPS to my evol collection. Currently Evol Mini .22 only

@Yoda_1794 - I get close to 40 shots on my EVOL 15 @ 40 FPE using H&N 21.14g at 926 FPS. That's about the highest I get - a bit more with some heavier pellets but not much. I have the reg set at 2100 psi (stock from AoA/Tom) and the hammer spring is about 1/2 way down. I suppose I could milk a bit more, but I'm extremely happy with the grouping at this level so I won't tinker with it. With a 3" extra barrel and a bit of tuning, I think you could get 50 FPE and have some great groups.

Thanks for the reply Pfddi. Is it safe to assume a higher spot count than 36?

This thread is dedicated the the American Air Arms Evol. A while back someone posted asking for a thread like this. I thought that it seemed fitting to compile Evol threads, information, videos, photos, and questions in a single thread for easier reference. This will take some time to do. I am far from an expert on these guns. I'm just an airgunner who enjoys his Evol. My impression has been that this is a well-built and thoughtfully engineered air gun. It's not fragile or made from cheap parts. Some of the most intimidating tasks concerning these rifles (for me anyhow) were taking them apart and tuning. So I'll begin by posting videos and thread about these tasks first.

Evol Tear Down Video
This covers removing the barrel, barrel cleaning, degassing, removing the reservoir, removing the regulator, swapping AR pistol grips and buttstocks. It also discusses removing the buffer tube. There are some nice reassembly tips in here.

This video shows you how to degas your gun as well.

AAA Evol tweakage

Making some reg adjustments on a .30 AAA Evol. I'll say this, I like this build. Are they worth the money...............we shall see. The long accessory rail isn't rigid enough for my taste but that is the only real gripe at this point. Lowered reg to get my target speed in sight. Put it on...

Early Evol Setup by @mtnGhost

My AAA EVOL 30 Setup

I spent a little time on figuring out how to setup this rifle, and what ammo to shoot from it. Decided that it would suit me best as a hunting rifle for larger small game (up to raccoon size) out to 150m, and coyote size game inside of 100. Collapsable / adjustable stock with a flat spot for...

Changing Manometers on American Air Arms Evol .30 (User Perspective)

I’d had issues with older manometers sticking and not reading accurate pressure in the reservoir and plenum. I was informed that AAA no longer uses the older style gauges. After reaching out to Tom Costan about the issue I received updated manometers and instructions on how to replace them...

If you're wondering how durable this air gun is, take a look at Dana Web's Torture Test of this gun. This is a 3-part series entitled "Will They Survive" in which the Evol was subjected to extreme stress and tested against a couple of other popular air rifles for durability, accuracy, and consistency. The result is astounding.

My 15" .22 developed a leak in July , and I have chased my tail for over a month.
I completely disassembled it, including pulling the valve. After a fresh set of rings, still leaking.....
Got the reg gauge to seal to the adapter ring using a slightly over sized o ring, but still leaking......
Submerged it and the front gauge is leaking so I used another slghtly oversize ring thinking it would cure it. WRONG..... Second dunk in the water with the clear gauge cover renoved and it is leaking from the gauge itself internally.
AOA parts dept. has a new one on the way to me as of today. Gauge was $35 and the rifle is way out of warranty. Go figure:confused:
Removing the valve is really no big issue. You must remove the DO NOT REMOVE set screw, and the valve pushes right out from the front, out through the hammer bore.

As a follow up

DO NOT take the above as me griping and grumbling.
The rifle is 3 years old and never missed a beat until recently, and it has been shot oodles and lots. Evols are solid units, and I own 3. Mine was simply due for a service.
As a funny aside, I have officially replaced more O rings in my Evols than in either of my Impacts! So take that you fanboys 😉

So did you buy that 22 HPS? I was seriously thinking about it but it sold rather quickly. The benefit with that particular HPS model, aside from the longer barrel is the faster 15:1 twist rate. This gives it the ability to be a good slug shooter, as it was designed.

Your timing is too funny. I just sent AoA an email a couple days ago to ask about these. They said the same thing - they are in production now. I'm super excited to see what they look like. I'm really hoping for dedicated slug barrels... I would love to see their tactical with the 18in barrel shooting slugs at 55 - 60fpe!

Not sure I’m reading it right but does anyone know if the non-hps models will go back into production? I wouldn’t mind buying an original mini.

@RicL What I gather from the above pictured post is that he is going to continue to refine/improve upon the original Evol line. In short, yes it appears AAA will continue to produce the original Evol but with more accessory/customization options.
