Power, accuracy, ease of tuning, appearance

The included case needs to be just a tad bigger. As soon as you start adding accessories you need a bigger case.

Yep, it's expensive. However, if you're an air gun aficionado, it's worth every penny! I have the reg set at 140 bar, power wheel at 16, and Quick Tune a 4.5 and shooting 49g .30 cal slugs at 920fps. When I changed it to .22 cal, I dialed back the power wheel to 8 and was shooting 25.39g JSB KnockOut slugs at 950fps. No other changes were made. It's a dream to own.

Smooth operation, quiet and hard hitting. Easy to load, getting 120 shots per fill.

At the price should come with 2 magazines and a rail under the bottle, but I guess they leave most of the customization to the purchaser.

Added a scope and green laser. Great shooting makes it easy to quickly go through a tin of 150 pellets.

Just added DonnyFL Saber Tactical FX Impact Low Profile Arca Rail 3, Universal Picatinny to Arca Short adaptor, a UTG Recon 360 TL Bipod and UTG 4-16x44 OP3 Compact Scope with UMOA Reticle and Swat Wheel. All these products up to the FX quality standards, look and feel great. This gun is incredible.

I bought this rifle refurbished. It was literally brand new everything is working on it. Everything came in the case just like if it was sold as new. I previously bought this rifle from Utah airguns so I know what comes in the case. I never have got an fx sticker in any rifle case. I paid for the extra $10 service this rifle was in excellent, mint, top condition and serviceable right out of the box. I can't praise enough, I am very happy with this purchase

Don't change anything. Pay extreme attention to detail. If you don't you're bound to disappoint and upset a lot of air gunners. We take this seriously! For now, keep up the good work!

My experience buying refurbished has been a good one. It was brand new or "open box" My experience may not be yours that's the risk you take but, I saved a significant amount towards the purchase of a brand new FX impact M4.

My favorite part about this gun is the endless amount of upgrades accessories you can throw at it. The fact that you can just swap barrels between different calibers instead of having to purchase a whole new gun is just awesome.

Nothing as of right now

Looks awesome. It was consistently accurate

The price, the weight. The reliability.

The gun broke in less than three months after receiving it. It started jamming, wouldn’t fire. Twice it fired just as I cocked it, I was nowhere near the trigger.its been in the shop for over a month for over a month.i have two other airguns never had an issue with over three year of use both were $400. Fix could do better. If I knew this I would have purchased something else for sure. Not happy!! Especially for over $2400.

This is a great gun very easy to tune the trigger is great. Very accurate. Looks great. Well worth the money

I wish wasn't so expensive. But it is extremely well made. After my first shot I was very happy. Highly recommend fx impact. In fact you cant go wrong with any fx products

With all the YouTube videos on tuning and other functions plenty of great knowledge to help your experience.

Backyard plinking, general target shooting, some small game and pest hunting

It could be lighter, but probably wouldn’t be what it is. But I thought it was heavy out of the case by the time I added a scope an arca rail for a bipod it became heavier to me .

It’s a great air rifle, get you one you’ll enjoy it.

I bought the 25 cal. Very quiet with included moderator. The trigger out of the box is amazing.

None so far

It was a lot of money but after my first pull of the trigger I am so glad I bought this rifle.

This is an amazing gun. I bought the copper and black finish - although it looks more gold and black to me. The gun is light, easy to shoot, powerful, accurate, and cool looking. The factory settings send an FX 25.4 grain pellet downrange at about 970 fps. I have been able to achieve shot on shot holes in paper with very little effort. I have only had the gun a couple of weeks, so I haven't tried to shoot anything with it, but I am certain that when the time comes, it will be up to the task. I have watched about a hundred videos on how this gun works and believe that when the time comes, the gun will be able to be customized in any way I desire. The gun is incredibly quiet. Using the factory settings, I have been shooting the FX 25.4 grain diabolo pellets at about 970 fps and putting shot on shot at 35 yards. I am so happy with the results!

The elephant in the room is the cost - this gun ain't cheap. I was able to buy this gun a day or two before a price increase, but it was still the most expensive gun I have ever purchased - air or powder. I only have a couple of things I am a little disappointed with: The case is amazing, but with a teeny-tiny bit of effort, they could have cut the inside of the case to hold the rifle WITH the moderator attached to the rifle - the gun with the moderator is only about a cm too long to fit. A second thing is, and it's been mentioned by lots of people before me, is that they did not include the allen wrenches you need to modify the gun... I ordered some ball-head allen wrenches, but they haven't come in yet - hence no tuning, yet. Why have a gun that can be modified any way you want and not give you the basic tools to modify it - especially at this price?

If you are going to buy this gun, you need to be prepared to support it. It takes a lot of high-pressure air. I have a 96 cu-ft bottle, but it only fills up the gun a few times before it has to be recharged. I have a second 100 cu-in bottle that will not take the gun to full 250 bar charge. The website says that the gun will produce 130 shots per fill - I find this to be more like 75 shots (3 Mags) using the factory settings and FX 25.4 diabolo pellets. I have not yet tried slugs at all. The point is, this gun is a top-of-the-line gun, basically, you will need a way to charge the gun, and a bicycle pump will simply not work. Consider getting a compressor that is larger than a shoe box - or have a dive shop with a high-pressure compressor next door.
