This is a fantastic deal and a very impressive gun. Of remarkable note are the four K baffles used in the suppressor, it's the only air gun doing this if I am correct, they do work, the report is akin to a 400 fps CO2 air pistol like the C11. Fit and finish is excellent, nothing looks cheap on this gun. It's an unbelievable deal at the listed price and more so if you can use one of the discount offers, plus it qualifies for free shipping. It's feels like a gun that can compete with the top priced guns on quality. As for power it drilled a brown box Crosman Premier across the chrono at 699 fps punching through one and 3/4 bars of my still in the plastic wrap Neutrogena soap bars. Sacrificing one of my rare out of production vintage 8.4 gr. Silver Jets the chrono recorded 647 fps. All the issues with loading the CO2 I read about escapes me, it couldn't be simpler or easier, it's totally trouble free. I am so liking this gun. It's accuracy is beyond belief and it just feels ergonomic.

I would just love it if some skilled master or hobby machinist invented an easy way to turn it into a repeater, but actually slow fire is the best way to use CO2, still it would be nice to have the repeating option. I find the bolt easy to cock and the automatic safety is no hinderance at all and designed for a natural no wasted movement of the trigger finger to disengage. My some what barrel shaped Silver Jet pellet fell naturally into the loading tray but the Premiers took some minor fidgeting half the time to make sure they went in nose first. Loading pellets is probably the only real place you might encounter issues. If you tilt the barrel down the bolt slides forward getting in the way of the loading trough and if you tilt the barrel up I can see a real danger of dropping a pellet through some large openings all the way down into the trigger mechanism area. You will want to hold the gun horizontal for loading pellets. I'll look for a fix on closing those large openings someday.

I am not a scope guy per se but I see nothing wrong with the included scope, it looks like it would provide good service for the short distances that guns in this power range have. Since I often shoot in dim light I opted to install the 123a powered Crosman laser all the way back on the action using a low profile Hawke adapter. Back there it is an easy turn on and off with the thumb of my trigger hand. This is one of those guns that just keeps me looking for more and more reasons to shoot it. I would like to see 2, 3 or 4 more K baffles added to the stack to bring it down to a whisper where the trigger is the loudest thing heard. As it is you just have to shoot it to believe it has this much power. It's pretty obvious the O ring likes to get all swollen up and needing a good half hour before reinstalling so I bought a package of recommended replacements and will just slip off the swollen one and put on a fresh one while it shrinks back up if I want to continue shooting without delay.

Accuracy, consistency, noise level-very quiet.

Update: after 10 months or so and 1000's of shots I'm still very impressed. I added a 3-9x32 Bug- Buster scope which was a big improvement. Also, when the o-ring on the pressure relief valve developed a rip, I first tried to order replacements from Archer, but the order was lost by the post office. In frustration I contacted a seal company in San Diego. They had o-rings of the proper size. I bought 20 for less than $5 and 4-500 shots later, I'm still on the first one. BTW I recently was gone for about two weeks and when I returned it was still holding a full charge of CO2. Finally, as I go through a varied supply of pellets I'm finding it's pretty tolerant and I don't need to adjust the scope much at all - just a few clicks.

very quiet; accurate when fully charged; nice weight & well balanced; ergonomic shape; bolt-action; adjustable trigger

CO2 cap - make an easier-to-use stock CO2 cap (although I bought an after market CO2 cap that just screws on and off and is super simple to use compared to the stock cap so no having to fuss about the factory cap that everyone seems to hate). Dove-tail scope mount - make the rounded-top dove-tail scope mount a flat top to be able to use more non-stock scope rings - don't lose the rings this gun comes with as they are made for this gun's slightly rounded dove-tail mount - using others I found may cause the scope to be off and harder to adjust. Scope - the fixed 4X scope it comes with is clear & works fine but the gun could use better optics or none at all to save a few bucks and get a good one of your choice. Safety - the safety engages everytime you cock the bolt which is a pain but it is at your finger tips so you get used to it. Make it ambidexterous - wouldn't recommend this gun for a lefty as the bolt and safety are on the right. It is single shot -would love a repeater version!

I bought this in hopes of finding a quiet air rifle that I could use in my backyard & FINALLY found one! Many air guns advertise as "quiet" & I guess it is a relative term. I have even bought a couple advertised by PA as low/medium quiet level & they are much louder than this one. It actually is very quiet, the "smack" on the target louder than the report. It is not a powerful pellet gun but still puts 8 grain lead pellets out at just under 700 FPS per the chrony tests. I didn't buy it or recommend it for hunting but for my purpose of backyard target shooting it's perfect. It's also very accurate. I swapped the fixed 4X scope w/a 4-16X AO. I use hanging foam golf balls for targets at ranges from 15 to 40 yards & it nails them each time. I found accuracy is affected as CO2 drops or if you leave the CO2 in for several days so plan to shoot 25-50 shots at a time or you're going to waste CO2. Found JSB Exacts 8.44 grain the most accurate in testing. Overall really fun air rifle!

Lightweight, decent trigger, .750" groups at 25yds out of the box.

Stop bundling the atrocious scope with the riffle. I shot the rifle 20 times before I couldn't stand the bundled scope anymore and replaced it. Just drop the price $30 and ship it without a scope. The Trigger could use a little work but it is decent out of the box. Change the material on the Fill cap O-ring swells up way to much.

You will need to have a stock of O-rings for this riffle. Good chance of screwing one up every time you change the CO2 cartridges. Not that big a deal if you have replacements on hand sucks when you have to wait on a replacement though. This rifle is just plain fun to shoot. So make sure to order A LOT of Powerlets.

It does not work; unfortunately the gas chamber leaks therefore rendering the rifle inoperable.

I would like the gun to be exchanged without any additional charges to me; this rifle has issues and your company was well aware yet failed to inform me.

Your customer service was not friendly making it undesirable to buy anything else.

This is a very quiet gun and pretty accurate. Feels good and easy to hold/aim.

With a scope on, it is very hard to hand load the pellet! I developed a technique of kind of rolling it in from the side. The scope it comes with is Umarex junk - very suspect and impossible to zero in well. I bought a nice Leapers for $40 and it pairs perfectly with the gun and I can now trim a fly's whiskers. Loading the 2 CO2 cartridges is weird and piercing the 2nd one you have to play with this relief valve that just makes no sense. They could have put one in the handle and the other where it is now?

The safety engaging every time you cock the gun is annoying. Rather have a regular safety any day. Kind of one of those safety ideas that must have come from a desk in Washington! You know what I mean.

Quiet, accurate.

Include extra o-rings with rifle. Every flashlight I buy comes with extra o-rings for water proofing. It is not integral for use of the light but you still get them. These o-rings are integral for using the product. Not only do you not get them but Umarex did not even answer my email regarding them I found 100 of the original o-rings on Amazon for $12 and change.

This gun is quiet and accurate out to 30 yrds (3/4 inch patterns at 25 and 30 yrds; 1/4 inch patterns at 10 yards. Fit and finish is excellent.

Scope is adequate, but accuracy is dramatically improved with a 3-9X32mm scope. Not really a hinting rifle, but it does work on chipmunks, HOSPs and Starlings.

JSB Exacts (7.33, 8.44 and 1.34 gr) are best in this gun. I use the lighter pellet when there is little wind, and the heavier pellets in windy conditions. The heavier pellets are also better for taking out small garden pest. Gun is so quiet that I can sometimes dispatch several garden pest before they catch on to what is happening.

Very quiet, superb accuracy with most pellets, and excellent ergonomics. It's my favorite rifle, of the 8 I currently own, and a joy to shoot.

I'm not a fan of the co-2 end cap system. I works but could probably be better. Should come with extra O-rings for the co-2 end cap. A lot of O-rings.

I've owned my Fusion for almost 8 months now. It has been reliable except for the O-ring on the end cap. I found an ordinary O-ring for a faucet to replace the original O-ring.I use Pellgun oil on the co-2 cartridges but I use 30wt. non-detergent motor oil on the O-ring. So far it seems to work better. I'm very happy with my Fusion and it is the most accurate air rifle I own.

This is a very nice gun. Perfect for back yard or indoor shooting. I have been very impressed with its accuracy.

It would be nice if loading pellets was a little easier.

A scope upgrade will improve shooting experience. Loading the CO2's is not a big deal and is easy to learn. Really nice gun for target shooting and plinking. If this gun bothers neighbors you may want to consider moving.

Quietness, accuracy, trigger & weight.

An option for a better scope.

I purchased this because noise can be an issue in one of the areas where I shoot. My primary air rifle is an Air Arms TX200 which is a little too loud in this area. I was very pleasantly surprised with the Fusion's quietness (VERY), its accuracy (pretty consistently 1" or less at 30 yards with 8.44 gr JSB Exacts) and even the usability of the included scope. While a scope upgrade would be very nice, I don't feel any urgency about it. Loading the CO2 cartridges is easy after the first time or two. The instructions by Rick Eutsler on his Airgunweb video were the best I found. Loading pellets takes some practice and might be difficult for larger hands. Mine are average size and I've found that rolling them in becomes easy. Finally, I included the $10 checkout to ensure I would have no problems with the seal. So far, 3-400 rounds late, all's good. Overall, a great choice when a quiet shooter with excellent accuracy for the money is needed.

Quiet, accurate

Almost cannot get a pellet to load since it is under the scope and no open sights.

Nothing

Everything

I bought one over a year ago and it still doesn't work. It leaks air and on the advice of Umarex I bought a new o-ring. Still leaks. Then they blamed Crosman co2 as the problem. I then bought Umarex co2 and it not only still leaks it also did not puncture the first co2 that is inserted. So I put in my junk pile.

Everything, I admit I never mounted the kit scope. But by looking at it the kit scope seemed clear, however it has never been on my rifle. Very light (before I hung the huge scope) shoots like a laser, what an amazing little rifle.

It would be nice to have a lighter trigger...or adjustable. The cap O' ring is a bit soft but so far I have not had any issues.

Loading pellets is no problem, again I am not using the kit scope and rings, so I have a little more room, just roll the pellet in, very well thought out. I also have not had any problems with the bolt pushing the pellet in. Loading the the CO2 Cartridges is really no problem, Just read the manual and watch the videos, I have also had no problem de-gassing the rifle with the cap, however remember to let the rifle sit for a while after you do that, the red O' ring will swell and you could damage it. Bottom line is this is a great rifle. I bought it because of problems I have had with QB78's I have 2 and they leak like crazy and I can't get them fixed. This rifle replaces them perfectly...except for the price. An amazing shooting rifle. Mine seems to shoot best with H&N Finale Match Pistol Great little gun I can't recommend it highly enough...you really can't go wrong.

This rifle is very quiet, just what i ordered.

I've only purchased a few air guns so far , but all of the co2 guns ive tried have the same fault. they all seem to have a tricky or difficult way to load the co2 cartridges. This rifle is no exception. I did read the instructions and still had leaks, after many spent cartridges i think ive finally figured it out.

Very accurate, quiet, works good, lots of fun.

A pistol grip stock like an AR15 but that is a personal preference of mine.

I do not bleed off the CO2 using the valve. It is simple to just dry fire until the remaining CO2 is gone. I leave the CO2 in the gun as long as it has enough power to shoot, this is sometimes a week or 2. I use a 6.5-20x AO scope because I like the accuracy.

Nice solid guality feel, Accurate, double CO2 powelets twice the # of effective shots. My gun does not leak i get great shots several days after replacing CO2 cartridges..

Nothing, it works fine..

The co2 cap is a piece of cake to use, i wont tell you how, read the instructions get your head around it you will love it. I have tried an after market CO2 cap believe me the origional cap is hands down a much better cap because it allows you to release the gas when co2 cartridges get low. Orings you can find any where use your head.

super quiet super accurate

size of the co2/ chamber and the o ring sucks always leaks out I replaced the o ring several time but nothing seems to work done spending money on a gun that I only get 5 to 10 shots out of definitely not worth the time nor the money I would not recommend this air gun to anyone.

scope sucks hard core pellets are hard to load but still a million time easier then a break barrel I also hunted with this gun for birds/ground squirrels /and rabbits it preformed flawlessly every one says not to hunt with this gun but being able to shoot them in the eye almost every shot out to 50 yards is remarkable and still getting insta kills at 50 yards

Very quiet, light, accurate and good looking.

None

First airgun had issues with safety and cocking. This is a replacement and everything looks ok. Never had problem with gas leakage.

Extremely quiet. No sensitivity to how you hold it. Seems extremely accurate once the included scope was set up. Easy to use with younger kids too.

I bought the replacement co2 cap available elsewhere - wish that was included rather than the funky design.

It takes a bit of practice to load pellets into the breach underneath the scope - but you get used to it pretty quickly. I load from one side while looking from the other side - and I keep the rifle vertical so I can just set the pellet on the pin.
