The FX Wildcat MKIII Sniper takes an already great bullpup air rifle and makes it even better. It's packed with upgrades, the biggest of which is the superior control you now have over hammer spring tension thanks to the rear adjuster dial. It has 7 presets, but you can also fine tune it even further with the Allen wrench hole in the 8th dial position. FX also boosted the main block with increased plenum volume and valving, giving you better airflow and additional more powerful and consistent shots. The magazine received a major improvement as well, as this airgun now uses the same FX Side-Shot magazine as the Crown and Dreamline, giving you more than twice the rounds as the Wildcat MKII. This air rifle comes standard with FX's new Superior STX liner, an improved version of the older STX liner that allows you to swap liners and calibers, and a 1/2" UNF threaded muzzle lets you add a moderator. The Wildcat has even more additions, including a regulator pressure gauge in the stock that supplements the one at the end of the air tube. Plus, the MKII's 11mm dovetail optics rail is replaced by a new standard Picatinny rail. The biggest difference between this Sniper version and the Compact model is the size, both of the air cylinder and the barrel. You get more shots since the air tube is 70cc larger and more velocity because the barrel is 200mm longer, and the whole air rifle is only 11" longer and .75 lbs. heavier than the Compact version. Both models keep features that shooters already love, like the legendary adjustable two stage trigger, externally adjustable AMP regulator, and smooth cocking sidelever. Add up all the enhancements FX has made to an airgun that already set the standard for bullpup innovation and performance, and it's clear the FX Wildcat MKIII Sniper is the air rifle you need today.

I have it for 4 months now, i love it, its pretty accurate and handy. lot of shots 70-80 with one fill

Only thing was the barrel it is free floating I feel FX should have made this rifle with a fixed one. I guess if i fit a silencer it will affect the ZEROING.?

By mark millerDecember 8, 2022

Buy a good scope as it deserves one like a 5-25 power

Very accurate, consistent. Had a chipmunk problem around the property; literally hundreds, they just keep coming and I just keep wacking them. They had made a home in my landscaping and yard. Tried everything until I purchased the .22 cal MKIII..I live in a area where my suppressed subsonic .22 rifle was just a little too much and this was the alternative. Good choice, I could take "head shots" on chipmunks way out to 65+ yards with FX pellets with 3.5" holdover, dead on at 25 and I didn't change anything from the out of the box settings although it is tunable for more velocity.. It's amazing and the chipmunks are few and far in between now without anyone ever hearing a shot. Surgical head shots on problem Grackles out of the bird feeder. Impacts are brutal and explosive. No problem killing ground hogs with instant kills. Only thing was the barrel as it is free floating I feel FX should have made this rifle with a fixed but removable barrel band. I did add one with great consistency..

Needs a barrel band and the barrel threads are not a common 1/2" x 28 thread pitch so my suppressor didn't fit but the moderator it came with was good enough.

I'll be buying from Utah airguns from now on

I'm sure it will be great if it ever shows up

3 months order. They claim fx hasn't given any information on when to expect rifles even though 3 other gun dealers have same rifle in stock

By HoomanJanuary 29, 2022

Incredible accuracy, mind-blowing power, amazing STX barrel swap capabilities!! In addition to my .22cal, this is all I will ever need for my pcp rifle collection! Squirrels, foxes, rabbits, quail & grouse all day!!

Not one thing

By James USANovember 16, 2021

I just love this gun by far

Awesome gun my favorite!

I would change abosAbsolutely nothing

By MatthewUSASeptember 22, 2020

it shoots the cheap Crossman 14g.22 pellets all the way to the 25g nielson specialty slugs without skipping a beat.

So siiiiiiick I love it so much. Accurate, deadly accurate. Shoots anything I put through it with minor zeroing adjustments. I have shot 5 mags through it on one fill without accuracy loss. Thats 90 shots! With the hammerspring all the way open, too! Bam baby. I can literally shoot spiders off of my compost pile at 50 yds. Thats not exaggeration, I was going for rats, but you take what you can get at 1 in the morning am I right? Buy it. Its basically a cheaper impact IMO

bigger mag (it does have 18 shots, so i bought 2)

By HrooaiyaAugust 19, 2020

I love it

By the cat11USAMay 30, 2020

would like a walnut stock!

As it is free floating barrel, i guess it is affecting the ZERO on scope when i put the silencer. im planning to put/squeeze a piece of rubber between the barrel and the cylinder to reduce the barrel bend downwards because of silencer weight, for accuracy. any hints?

asked Kamal from Lebanon

Does it come with any case?

asked Mike from USA

yes, i received it with hard case, FX

Kamal from Lebanon

Mark three in .30 cal or Dreamline bullpup .25 what's better what would u choose the mark three has alot more upgraded parts n lil upgrades the Dreamline does not. Right?

asked Ryan from USA

Can I add a suppressor?

asked Slomkop from USA

Yes, it has 1/2unf threads right in the shroud. No adapter needed.

Mike from USA

is 308 caliber ammo the same as 30 caliber ammo.

asked William from USA


Mike from USA

Does this gun fire 30 slugs ?

asked Charles from USA

Yes it does. If you change the liner to a slug liner, you'll get even more accuracy.

Mike from USA

Buenas noches. Esta pcp Wildcat MkIII Sniper vienen para zurdos? Por que soy zurdo y me preocupa la pocision del Cargado y la palanca de carga

asked Ismael Gustavo from Peru

understand that this is really not designed for left handed but need more info on whether the magazine interferes with cheek placement or whether the non-rounded edge makes it uncomfortable?

asked jim from USA

Hi, can you use any type of high quality hand pump made for airguns for this rifle?

asked Sean from USA

Sure. As long as you can physically get your pump up to the max pressure

Raymond from USA

Is there a cheekpiece for lefty shooters ? can not shoot left with the stock cheekpiece.

asked jeff from USA

Is this air rifle Slug friendly or due to the rotary clip pellets only recommended?

asked Richard from USA

i used 21gr slugs, shooting great

Kamal from Lebanon

The magazine has no issues with the slugs I've used. Nsa and Fx brands. You should know that slugs can vary quite a bit in size. Therefore, there might be some on the market which may not be ideal.

Raymond from USA

Hi, what is the actual length of this gun? There is two numbers given here. 33.75" or 37.75"? Thanks!

asked Yuong Siang from Malaysia

Overall length: 33.75"

Mark from USA

can i have 700mm barrel in .22 cal if i order this gun?

asked Angelo from Taiwan

Caliber: .22" (5.5mm), Stock: Synthetic, Handle: Right, FX Wildcat MK III Sniper Synthetic, 700mm Barrel, .22

Mark from USA

I shoot left handed. Will this gun work for me? I know the grip is ambi but am concerned that the magazine would be in the way. I don't think the the lever being on the right side concerns me. What is your opinion on this?

asked Tom from USA

The magazine sticks out about 1 1/2 inch from the body of the gun. This is all personal preference.

Mark from USA

what all comes with the rifle?

asked David from USA

Includes hard case, one magazine and one fill probe

Mark from USA

Hi guys! I hope you are fine. I have a question regarding the adjustment of the wild cat mk3. May you please tell me which side to move Allen key in adjust screw to reduce or increase the hammer spring tension. A video on you tube would great to explain the whole modification

asked Faraz from Poland

For FX technical questions contact FX USA.

Mark from USA

asked Fred from USA

Mark from USA

asked Fred from USA

No The stock is ambi. The sidelever is on the right side of the gun.
