Things I liked:

Not much. My Fusion 2 is very inaccurate. It sprays pellets all over the place. There is no consistency in where it will shoot. I also had a lot of trouble with the magazines lining up with the chamber which resulted in mangled pellets.

Things I would have changed:

Magazines. I would also make the gun accurate. I tried 5 different pellets, including JSB, H&N, Air Arms, and the gun was extremely inaccurate and inconsistent. No matter what brand or weight of pellet I used the gun was horribly inaccurate and inconsistent.

What others should know:

My advice is to NOT buy this junk rifle. Stay away from this gun!

    Things I liked:

    My Fusion 2 is wicked accurate with Crosman 7.4gr. Destroyers and Pointed pellets both. It will routinely shoot all 9 shots of magazine into a half-inch or smaller group at 15yds on Caldwell rest indoors and has shot many 9-shot groups under 1.5" at 50yd, pretty incredible in my book. The ergonomics of the gun are fantastic and contributed to the outstanding accuracy. I also like the convenience of using CO2 cartridges, the 2x12g. are cheap, can be purchased at WallyWorld and provide 35-38shots before needing changed. The option to remove the adapter and shoot 88gr. CO2 is nice but I personally find it more expensive than using 12g carts. Also the floated barrel, chassis stock and built in picatinny rail are all features I like and add to the accuracy potential of the gun. It has more power than I expected as well, it puts decent dents in 1/8" thick street sign type material at 50yds which is more than I had figured it would do.

    Things I would have changed:

    I would invest in alot better scope before even firing the gun for the first time, the basic 4x scooe included with gun is okay at best. The trigger is another area I am not so fond of, mine has 4.4lb pull weight and boy its got some creep to it, not a great trigger pull to my standards. The CO2 adapter leaves some to be desired as it requires pliers to work properly although once you figure it out you won't have an issue with it. The magazines are kinda tedious to load with pellets and tedious to insert in the action as well. My Fusion 2 is kinda picky about what pellets it shoot as well, it absolutely WILL NOT shoot any RWS pellet I have tried and that would be 8-9 different shapes and weights...It will not shoot ANY of them accurately.

    What others should know:

    Remove the little rubber thingy on the bleeder valve and keep some pliers around because u need them to effectively pierce both CO2 cartridges. All the people writing about it never piercing both cartridges are not very familiar with airgun operation basics, use a pair of pliers a d you will never experience a leak or fail to pierce a cartridge. I get right at 4 magazines full or 36shots on 2x12g. Cartridges which I use aa lliberal amount of pure silicone oil inside the adapter with every gas change and have no leaks whatsoever. I have also used 90gr. JT CO2 and it works well except that you must remove the adapter to use the large cartridges, I stick eith the 12g. on costs alone. Also go ahead and get a better scope than the thing it comes with, sure it will work and isnt horrible but really you will never unleash the guns full potential with a free 4x scope. Keep the action screw fairly tight as well, and pay attention when putting mags in the action.

    Things I liked:

    I like the IDEA of the gun-having two air sources and moderated, with a magazine at a low price.

    Things I would have changed:

    I think they need to decide, if they are going to offer this gun then up the quality even if it means the price. The magazine is trash. You never knew if a pellet was going to come out because it didn't rotate reliably. Really someone at Umarex needs to revisit this gun. People want it but it needs to be better quality.

    What others should know:

    The gun leaked on the first loading. I constantly heard a hiss and after the first magazine it was done. After spending a while trying to get the stuck CO2 out, I loaded up two more CO2 cartridges thinking maybe it was me but this time it was worse and blew air all over. I decided to try the 88 gram so I removed the reservoir, and it looked like an ear of corn that you just pulled the shuck off when I removed it. There were metal shavings and slivers all over the threads. After 30 mins of cleaning that, I shot it again. Leak stopped, however the groups are awful and I got nowhere close to the shot count. Also some pellets keyholed and tumbled, so I think it's clipping the moderator. Buy something else.

    Things I liked:

    Quiet, Accurate with great CO2 saving features plus the build quality you expect from Umarex. Some users complain about accuracy but mine was shooting off hand 1" groups at 25 yards out of the box with only a few clicks on the scope get zero'd in. Maybe this is down to the shooter or possibly they were shooting in colder conditions that impacts CO2 power and shot consistency. If you are shooting in colder conditions keep the CO2 tube in your car or inside your jacket until you plan to shoot.

    Things I would have changed:

    More Power!! Maybe a 22 version? I also have a CO2 Crosman 2240 with a longer barrel and this has almost double the muzzle energy so the same power should be possible or even higher with this platform, without having to go to the PCP version.

    What others should know:

    When using the double CO2 tube you need to be aware it does have a valve so you can remove it after a shooting session to preserve your CO2 rather than letting it slowly bleed out whilst not being used.

    If you use the larger 88 gram you need to buy one of these if you want to have the option of removing cartridge without dumping all your CO2
    https://www.umarexusa.com/umarex-88g-co2-saver-airgun-accessory-2211132

    The 88 gram cartridges do not lose as much power as the 12g ones after multiple shots in quick succession

    Also note that if you use the 88 gram cartridges, you can't use the M-LOK mounts on the side rails. it may be possible if you shorten the M-LOK mount screws.

    You need to consider what you plan to use this rifle for, it is an awesome plinking gun that can deal with any backyard soda can infestations but like most CO2 powered guns, the power is limited so any pest control use is limited to rats at 10 yards max and assuming you have good chance of a headshot.

    Things I liked:

    Great gun! Just like with any other gun, you have to pay attention to how you hold it when aiming for dead accuracy.

    Things I would have changed:

    I would have made it better by letting it have the ability to pierce the 2nd 12g with ease.

    What others should know:

    Use the 88's and 90's! works so much better. With the right pellets, it can punch through a license plate! Did that by accident.

    Things I liked:

    The look and feel of it when you pick it up. Has a GREAT trigger right out of the box. Probably one of the best of the 12+ air rifles I own or have owned.

    Things I would have changed:

    The accuracy, no matter what pellets I shoot, is mediocre at best. I have shot over 14 different brands & styles. None do great. It is, however, very consistent it seems. About 36 good full power shots always in a 2-1/2 inch group at 25 yards. Minute of soda can accurately, But pinpoint accuracy, no. By comparison the Crosman Nitro Venom .22 I purchased from PA nearly 10 years ago is highly accurate! Just yesterday shot 4 of 5 Crosman Premere HP pellets into a fingernail size group at 20 yards. And that is often that guns normal. I dislike the dual CO2 chamber as it has been finiky and a very slow leak from day one. And I absolutely LOATHE the action. The bolt handle takes a good deal of force to load another round properly, and installing or removing the rotary mag is a major pain! Now more than ever I am getting jams and then double feeds trying to cycle the bolt. And I am being careful to do it right every time! This rifle is just very fussy.

    What others should know:

    I purchased this rifle in early October of 2021.
    Now it is April of 2023 and I have had a LOT of range time with this rifle. So my testimony and 30+ years of shooting experience I truly feel makes this a unbiased and credible account of this review. Due to manufacturing tolerances,
    your results may vary. I have in the very recent past modified the rifle a bit and now am getting somewhat better use out of it. But it is still prone to a fussy action. Smooth..........is one thing this rifle is NOT!

    Things I liked:

    Shoot with Crosman CO2,. Extremely silent. Never seen an air gun so silent. Two magazines with the purchase. A good start.

    Things I would have changed:

    1. Name above (Crossman) can't be found as air gun or CO2 capsules seller. 2. Try Crosman 3. Check wobble before shipping.

    What others should know:

    1. Upon arrival, the first thing noticed was the CO2 container was not firmly attached to the gun. It would wobble up down sideways
    2. I was not able to perforate both capsules at the same time
    3, Trying to find the sweet spot and have both capsules perforated was impossible to achieve,
    4. Not a heavy gun.
    5. No detailed information on the way the CO2 container about need to keep it loose or should be fix w/o wobble.

    What others should know:

    This gun takes 2 12 gr C02 cartridges and sometimes the front one does not puncture. According to other reviews I have seen, this is not uncommon. Others have suggested putting a spacer in between the C02's as a fix. I gave this gun to a friend as a gift, so I personally don't know if he has tried this as I suggested.

    Fit and finish are good, Scope is okay, shoots well, good for target practice.

    Things I would have changed:

    Should not have to use a shim between the co2 cylinders to make them work. The plastic pellet mag is just a lousy thing to do to a customer. Make it more durable and have it fit better and make them available.

    What others should know:

    Umarex makes a product that has parts attached to them that they know will wear out and need replacement. The pellet mag. is made of plastic, do they make this part available, NO I have had several on back order now since Feb. 2022. I will not be buying any Umarex product if this is the best they can do.

    Things I liked:

    This is a co2 rifle so I shoot at 15yrd targets,, I think this air rifle is a good value for the price; it's accurate, very quiet and not ammo picky. If your looking for a quiet tack driver with no recoil at a reasonable price this is your gun. I really enjoy shooting it.

    Things I would have changed:

    The magazines fit extremely tight and need to be filed or sanded down to load into the rifle smoothly.

    What others should know:

    This rifle was bought only to shoot targets, It has the accuracy for small game but not the energy.

    9 round mags. 88 or 2/12gr co2

    What others should know:

    This was the second one I bought. The 1st one did not include the double 12gr adapter. Had to buy it separately. The seal failed on it. They replaced it. Later the main sealed failed. They didn't reply to my emails. I liked the gun. So. like a dumbass I bought another one. This one came the the 2/12gr adapter. So. I now had 4 mags, 2 adapters. I felt as though the 1st one was a fluke. You know. Slipped through the cracks. I like the rifle. Any way. This second one was nearly impossible to load. The mags (old or new) would not go in easily. Spent more time fixing jams and fiddling with it than shooting it. Contacted PA, the sent me a shipping label and got a prompt refund. So all good there. And. Like a dumbass, I bought a used one on eBay.... coz I like the rifle.

    Things I liked:

    It's quiet, the magazines work well and its accurate.

    Things I would have changed:

    The included scope isnt for me. The trigger is light but the pull is too long in my rifle. The trigger looks similar to a QB78 internally, I'm going to put some travel adjustment screws in. I'd like it in a conventional wood stock, but that would increase the price.

    What others should know:

    I got mine a while ago and didn't shoot it much. Recently I saw some Youtube vids criticizing the accuracy and other stuff. So, I got mine out and put a different scope on, just for personal preference, and I can't stop shooting it!
    The magazines have worked for me with whatever pellets I have around. The accuracy is very good, no complaints. The only thing I want is more magazines. YMMV, maybe I got the Golden Sample?

    Things I liked:

    Solid construction, yet compact, lightweight and manageable.

    Things I would have changed:

    Nothing, great bargain. It's just fine the way it comes. Things I'm gonna do...I'm gonna take the bolt and carrier out for some fine polishing just to smoothen the action...also, gently remove some of the edges on the magazines that develop during injection molding plastic. This type of stuff naturally wears over time with usage, but I just like to help by adding finishing touches where and when I can.

    What others should know:

    It's a fun shooter. As the consumer, there are times where user error comes into play and pellet magazine Jams can occur. These can be cleared by gently sliding a plastic cleaning rod down the barrel to push jammed pellets back thru the magazine into the bolt carrier. 1) Unload CO2 or at least secure with safety switch and 2) I used a soft metal rod with a deburred end and gently lowered it into the barrel to the area where pellets were jammed up. Rifling grooves in pellet gun barrels can be easily damaged so be very gentle in your approach or get someone who knows what's up to assist. Resist the urge to force anything. If in doubt, seek professional assistance with a gunsmith or someone well capable of doing their own 'smithing.

    Better instruction manual. Doesn't clear show or state which side the pellet cartridge is input (left or right).

    Where in the manual does it show the # steps needed to properly cock the gun and the directions to achieve the needed final process???
