The FX Impact M4 is arguably the most advanced PCP bullpup on the market. With features like its Smooth Twist X Superior (STX) barrel system, improved Power Plenum 750 (increased post regulator volume), Adjustable Match Precision MKII (AMP) regulator, external micro and macro hammer spring tension adjustment, and external valve control, the customization options are almost endless.
The M4 includes an improved reversible side lever and a new dual transfer port (.22 and .25 only) that lets you optimize performance for both pellets and slugs. Plus, the new Quick Tune system gives you an easy way to adjust your air rifle with very little need for tools. Of course, the M4 also features the rear Power Block. With multiple barrel lengths and calibers, there's a version for just about any shooter out there!

Upgraded from hatsan factor rc to the fx m3 and its night and day difference. Totally worth extra $1k
Pros
Everything about it is beautiful and I am very happy with it
Cons
Small air leak at the angle gauge plug plug. Was able to fix it myself
I purchased this in a .25 caliber and after sighting it in it started to have a slow air leak. I contacted fx airguns and the sent me a shipping label to get repaired. Recieved air rifle back and shot it 5 times to sight in and after only 5 shots there was a significant air leak. This is not worth the money. Saw a YouTube video saying this guns only kryptonite is that it is bad for leaks. When I pay this much for something it should work every time I take it out of the case. I have had it to long now because of waiting on repairs that I can't get a refund. Worst 2 grand ever spent.
Pros
Feels good to shoot
Cons
Leaks air to much
Im notorious for regretting my purchases, especially large purchases. This time I dont Feel bad at all. This thing is a tack driver and I love shooting it.
Pros
Love it, dumped a yote at 50yards on the second night.
Cons
Wish the magazines were not so thin. It limits the length of pellet or slug too much. For a rifle that is so adaptable it is unacceptable to be limited by this major factor.
For a compact air rifle this fits the bill perfectly. I wouldn't hesitate to hunt out to hundred yards with this thing. The thing is a scalpel, hitting Tums tables at 70yrds all day long. Do yourself a favor and add a good scope, this gun deserves it.
Pros
I have the Imapct MK3 500mm .30 and must say this thing surprised me. It's insanely accurate with no hold over out to 70+ yrds. I'm using both JSB Diablo's and Hades in 44.5gr and both dead to nuts accurate. I actually detuned the gun to 870fps. Power wheel on 15, Macro 3.75 and front adjustment 5 turns (Marks) out.
Cons
Nees a moderator, pretty loud otherwise. I put a DonnyFL Ronin from my Maverick on it and that tamed things down.
Buy it now. I bought a 9422 Winchester years ago for 100 bucks. It’s worth 1800 now. I would trade it for another of these.
Pros
Out of box one shot zero at 15 yards with ATN 4kPro. Next shot 83 yards. Held slightly high and left for 10 mph cross winds. Shooting at a lodge frying pan. The impact of pan is louder than the gun. Hit it every time. Thank you FX for getting it right!
Cons
Sure I would like it for half the money. But, perfection doesn’t come cheap. No buyers remorse here. Love this gun!
Pros
It's a great gun and it's easy to maneuver. I got mine a month ago and it's flawless. Good job fx.so, far , I can't complain.
Cons
None
Pros
I can say one thing that after I bought an average scope 5 to 25 vortex black diamond and used the jsb exact king pellets I can get 5 pellets on top of each other at 100 yard after good calibration.
I didn't know that a gun like this ?? existed. I can get 5 pellets on top of each ohers if there is no wind. I hope it doesn't breakdown
Cons
Heavy
This gun is worth the wait and very quiet even with the stock moderator. You won’t regret this purchase.
Pros
I’m a long time powder burner and have been using air guns since I got my Crosman 760 in the early 70s. I’m new to PCP and purchased a Hatsan Blitz in .25 about 6 months ago. My FX M3 in .30 arrived about three weeks ago, and I’m blown away. Deadly accurate even when using lesser quality pellets. The technology, fit, finish and accuracy of this PCP are simply exceptional. I love stacking pellets with this rifle.
Cons
Other that a longer picitany lower rail, I can’t think of a thing that I would change. I’d love to see FX develop gun in the M3 format with semi-auto capabilities. That would be a serious game changer.
Thank you airgun depot great communication super fast shipping
Pros
Very quiet and accurate very user-friendly
Cons
Pricey but you get what you pay for

asked Tim from USAHi, I'm stuck between this rifle= (.25 calFX Royale 500) and the rifle (FX Impact X) (.25 cal) Please tell me which rifle is more accurate Which is better for distances above one hundred meters? I need your experience. Thank you

asked makra from USADoes the MK3 come with a barrel harmonic adjuster like I've seen on a couple of videos ?
asked Rusty from USANo it does not it also features a empty moderator and the cartridge is still made of plastic. $2300 real disappointment FX
Roger B from USAWill Mk II Impact barrels work in the MK3 ?
asked Rusty from USADoes the 600 barrel shoot slugs as good as the 700 barrel
asked jonathan from USAThe 700 mm barrel gives you some extra velocity . But it depends what barrel liner you have . The Superior X liner shoots both slugs and pellets very accurately . If you shoot both I recommend it . If you only shoot slugs the Superior X heavy will shoot slugs accurately . I would get the 700 for over 150 and over shooting .
Rusty from USAComes with case
asked Robert from USAYes , a very good hardcover case .
Rusty from USAI see that it is equipped with Moderator, but is the barrel threaded to accept a aftermarket Moderator?
asked Don from USAAre threads on gun barrel universal for different size Moderators?
Greer from USAWhat cal. Is the most accurate if any?
asked Robert from USAHi can you switch calibers from .177 to .35
asked Rudolf from USACan you switch calibers from .177 to .35 cal
asked Rudolf from USARe: FX Impact II... how much does SOUND increase with larger calibers?
asked frank from USAAs you get into the larger calibers there is more air used in each shot. The firing noise goes up. You need a larger/longer moderator to keep the gun very quiet.
Mark from USADo any of the FX model PCP air rifles come in left hand ?
asked James from USAThe new MK3 model has a switchable cocking handle and is improved in many other significant ways .
Rusty from USAThe FX line has ambidextrous models but all the cocking side levers are on the right side of the gun.
Mark from USAWhat 700mm 30cal slug liners do you have?
asked Dwayne from USAAGD-A9188 $109.99
Mark from USAHow lite can you adjust the trigger to?
asked William from USAI.ve been shooting FX Bobcat for many years in 30 cal and have killed lots coyotes and varmints with no problems. I'm shooting out to 120 yards comfortably. Been reading about the slugs lately and they look like you can get lots more distance and energy from the slugs? I'm looking at the Impact X MKll and was wondering if it comes with the liner to shoot pellets and slugs? I'm going to just shoot slugs only in the Impact in 25 or 30 cal trying to make up my mind which cal I will need?
asked Alan from USADoes this weapon come with a case?
asked Roy Burkett JrCan you tell me what is the difference between the FX Impact X, the FX Impact MKII, or the FX Impact X MKII? I'm not sure if these are different models, or basically the same rifle.

asked Amber cruzHow much are the extra "X" barrels: I'd want a .25 & .30 (both in 700mm barrel lengh ) Is there a liner for shooting slugs yet? Is there a difference in price for the telescopic sound suppressor or the fixed one (I like to be quite) Use is Varmet control on our farm. Is there any talk of getting into .45 or .50 cal guns? thx

This is the one. Been looking through several Air guns and this one checks all the boxes for me. When you get the M4, be sure to download the latest manual. There are some subtle diferences.
Pros
Lightweight, no electronics, quiet, very accurate
Cons
pricey but yo uget what you pay for.
