I have a .25. Well made. Solid. Launches 34 gr lead up to 70 ft lbs. Yup. Full auto. 

Gun is quite accurate. Overall just a hoot to shoot. 

Couple of notes:

Upgrade to the 580cc bottle. (will take an fx bottle). 

Get ready to spend a boatload on pellets. 

The trigger is not great. Kind of feels like a revolver DA trigger. The pull is long but the break is clean. IMHO probably the biggest issue with the gun. 

Stock CF moderator is LOUD. As in "hey everyone I have a full auto gun in my backyard" loud. Expect the SWAT team. Donny makes an adapter to take a 1/2 UNF moderator, but only for models before Aug 1st 2020. He is making one for the newer guns but it isn't out yet. 

Can't wait for the .30. 




 
I have a 25 caliber and it shoots very well. I did have to send it back to Airgun's of Arizona for an internal leak after several thousand pellets fired. They were very fast and I had in back in about a week. I shoot JSB MKII's at about 920 FPS and it will throw them out at 980 FPS using just the power wheel. I have tried slugs but couldn't get them to shoot well so I gave up. My only complaint is the trigger, the first stage is really long. My Huben is a hundred times better but you can get used to it. If they ever sell a mod to fix it, I would buy it in a second. Feels solid, shoots very well, and has a bunch of power.




 
I've got one in .22cal. I bought it used from AOA, good people, great service. I'm guessing it was a trade in on a more reliable gun. Mine is a leaker,no more than 400 rounds and began to somewhere deep in the bowles of it. After trying to fix it myself, I know not recommended but didn't want the down time. I finally sent it in for work, no cost, warranty covered it, great speedy service. When I got it back worked for 3 shots, same problem, back to AOA, waiting for it to be returned. I don't know if there are design flaws with the gun, they did one upgrade on it. It's a gas when it works. I have said I would buy another but have since changed my mind, unless I was assured the problems have been rectified. My peeves with it were wishing the safety was on the right side so that I could operate with my trigger finger, trigger improvement and a cut out on the magazine housing to facilitate emptying the magazine. I hope they get the bugs worked out than it would truely be a great gun.
 
My .25 leaked from new too. I sent it back to AoA-it still leaked. I sent it back and they replaced it. That gun held air like a rock star and shot like a laser. I sold it because I was worried about it down the road, and, I figured they would come out with the larger calibers I really wanted. To hold me over, I bought a .30 Uragan. It has been perfect out of the box and is just as accurate.
 
I bought a .22 , it was my first pcp. It had a slow leak from day one, (about 10 percent per day) but I wanted to play with it until I got bored of it, it got a more serious issue, or I got a another pcp to play with. Its hard to put down because its so much fun to play with. It went through the air like crazy until I cranked the power down. The pellets were going through the rats until I switched to a hollow point. It was at 1050 fps with a 18.52 barracuda hunter. After I cranked it back to 930 fpe I made more than 80 shots per tank before refill. 

After about 600 pellets I notice the pellets coming loose in the magazine. Next thing I know I as I pull the trigger, I hear a weird noise and don't think the pellet came out. I dropped it off this monday and have not heard word about it yet.
 
I have one in .25. It made the obligatory trip back to AoA for repair, but has been holding air since then. (I should go check, haven't shot it in a few weeks.) Full auto is a fun novelty, but I've only burned 2-3 magazines that way. Love it for semi-auto though. I don't think the trigger is bad at all - it's not heavy, just long and there's not a perceptible 'wall' before it fires. Takes all of 2-3 shots to get used to it. I wouldn't compare it to a revolver - it's not at all that heavy, nor does it 'stage'. Accuracy is very good. I like the moderator it came with. I tried a DonnyFL Sumo on it and didn't notice a difference except that it's bigger and heavier. I took the Sumo off when it went back for repair and haven't put it back on. In either case it's not a quiet gun, but it's friendly enough for my backyard.

I was one of the first to have an LCS, the one I reviewed was in .25 caliber. I loved the gun so much I ended up getting my own to keep. Actually loaded up to leave early am for two days in the backcountry with the LCS. I've really enjoyed the gun and have had no issues with it knock on wood. Here is a video that may make a few warm and fuzzy. Hopefully I can have a new video out next week.

I purchased my SK-19 .22 from AOA. Wanted to compare it to my Hubens. I will say its extremely accurate. I use Jsb 18gr. No fliers or pellet spiral. Once sighted in never adjust scope. My only complaint is the trigger- it is extremely long with no wall. Its not hard. I have noticed if I put the selector between the semi and full auto mode its a lot better. I am going to tackle the trigger sometime down the line. Just hate to mess with it when it shoots so good.
