Description
Setting out to develop a true hunting powerhouse, FX Airguns delivers the Impact M3 .35 Caliber. Retaining all of the adjustability and desirable features of the existing platform and some big new improvements, the Impact M3 .35 Caliber brings power and precision together in a marriage made in airgun heaven! Thanks to the upgraded Power Plenum 720, the Impact now ventures into large game hunting territory with authority.
The Impact M4 .35 Caliber features an 800mm Smooth Twist X Superior barrel liner, set up to deliver stunning performance with larger pellets. Sending pellets downrange at high speeds and generating over 156 FPE (with the FX Slug Power Kit) at the muzzle, the Impact M4 is firmly a part of the medium and large game hunting conversation. Coming standard with a removable 580cc carbon fiber air cylinder capable of a stunning 45 shots per 250 BAR fill, shoot with confidence whether you're in the field or in a benchrest competition. The premium side shot magazine holds 18 rounds in .35, so you always have lead on tap.
Of course, the beauty of the Impact platform is the ability to change calibers and settings at will. The highly touted AMP MkII (Adjustable Match Precision) regulator, micro and macro external hammer spring adjustment, and external valve control adjustment are all at your fingertips on the Impact M4. And because the rifle utilizes the Smooth Twist X liner system, swapping calibers or liners is a breeze. The ergonomics are perfect for shooters of all shapes and sizes, and make the operation of the rifle seamless. And the quick set trigger ensures you have full control over each and every shot, to place them exactly where you desire.
The rear Power Block sets the Impact M4 apart in terms of power adjustability. The power plenum stages the power capabilities of the FX Impact, the rear block handles that transfer of power much like a car’s carburetor. FX has completely redesigned the rear block and the valve house which allows for better air flow, efficiency, and power potential.
The Power Block will be especially useful for those who desire to shoot heavy slugs. The pressure in the plenum can better translate to the pressure behind the slug upon firing, allowing higher speeds and power. Those shooting heavy slugs are encouraged to add the FX Impact Tungsten Hammer weight to also allow for higher working pressures.
If you've been itching for a big bore that offers true precision without skimping on power, the FX Impact M4 .35 Caliber is the rifle you've been waiting for!

10 of 12 FX Airguns Impact M4 .35 Reviews
Shoots well out of the box. I have the pre Power block which I purchased in early 2022. The bronze, IMO. is the better looking of the two choices. My came shooting at 865 FPS with 81 grain pellets. I can punch a hole through a 1" pine board at 100 yards. Its powerful, accurate and is very adjustable for power. I have upgraded to the power slug kit from Huma Air and tuned the regulators (155/135 bar f/r). I am shooting at 905-915 fps now w/ 81 grain pellets. This is one of my favorite PCP's to shoot now. I am happy with the gun and would recommend it to others.
Things I Would Have ChangedI think the AMP regulators are build too cheap, plastic piston. The second regulator is difficult to adjust (in trigger guard). Both my regulators have shown creep over the past year. FX parts are pretty well made BUT the metal is way too soft. Thus can be damaged very easily.
What Others Should KnowParts are easy to get @ FX USA. They ship quickly and the staff is helpful. I upgraded to the Huma Air -regulators, and power slug kit. I did install the new power block but I did not see any improvement in fps. Maybe I am using the wrong transfer port? FX tells they are different but didn't explain how.
Mine shoots FX pellets and JSB equally well but not Grizzles to well. One hole groups at 35-40 yards.
The ability to adjust a lot of parameters to optimize your results with different projectiles. The relatively light weight. The side lever loading/cocking.
Things I Would Have ChangedNot much comes to mind.
What Others Should KnowMy rifle seems to have a leak that is slow enough to not immediately be obvious and that has been with the gun from before I got it. I have never filled the gun beyond 232 bar. While I am not sure how many rounds I should have before it comes off the regulator at full power, I get more than a mag for sure. But I have seen the pressure drop over a two week period after a fill from the Nomad II from 232 bar to about 130 bar as measured by the reservoir gauge. During that time, the gun was not fired or cocked and was always in a relatively constant temperature environment. My calculations say that the reservoir air temperature would have to have been over 252 degrees Celsius immediately after the fill for the drop to room temperature to solely explain the pressure difference. Unlikely, but I am not sure that it is a serious problem at the moment. Only know of the 81.02 gr. pellets (FX and JSB) as recommended ammo. Ordered April 12th and still unavailable.
Powerful and accurate. The accuracy is incredible.
Things I Would Have ChangedI would make it a flat top with an option to remove the scope mount that looks kinda like a carry handle. Then Id have an option for open sights. Yup. Open sights.
What Others Should KnowMine showed up and it appeared to have been handled somewhat and the moderator was missing. Contacted Pyramyd and they said it was probably messed with during shipping. They gave me FX contact info. I am surprised that the company I paid over two thousand dollars to for this rifle is not equipped to handle the issue. I know the FX moderator is a cheap POS but I shoulda got one with my purchase and IMHO Pyramyd should have handled it for me.

the gun is now set up the way i like and very straight shooting , it is used for hunting here in florida and has done its job very well because of the pellet goes exactly where i want them , i have a 22 cal slug liner also and it has taken more pests ,nutria , rats ,racoons possums , crows , otters, copperheads ,moccasins, and iguanas ,does so pretty quiet . i am a landlord of multiple properties ,also own a small marina , i have multiple pest complaints and the 22 with slugs on the 35 platform is the real deal ,dont know why more people talk about it . you can send any weight or style slug you like at almost any speed you want for safety or power . really. i have hunted and fished for a living for over 40 years, son of a man that ran several gun ranges in the navy grew up in the woods on powder guns . no neighbors for 3/4 mile one way and 10 another in florida , most fun gun i ever had , out of hundreds . i am 60 kids have all firearms , i have 16 air and hooked .
Things I Would Have Changedmanometer leaked out of the box, i had one that fit so of course shot first day. need to fix them now the plenum meter started 2 days ago reason for this post . but i have shot over 3000 rounds , i know addicted i am told , makes me happy. next have had a 30 cal barrel on order for 4 months now ,no barrel in sight? i have high hopes for the 30 on this platform . it comes from using 30 cal in many diff guns ,if you hunt you know seems very stable at all ranges and grains. so 35 owners should try new cals ,fx please get them to us! favorite gun and ear holes at 5 to 150 make it that.
What Others Should Knowif you can do it( pull the trigger) its a working gun and i use it at work , makes that part of my job something i look forward to because it does exactly what i ask it to .
Very well made, beautiful fit & finish, great trigger. If you're in the market for a .35 this is the one! Mine factory stock, averages 850 fps, & gets 42 honest shots before it starts to fall off the regulator. It hits hard & has a phenomenal shot count. Gonna be a little pricey to shoot, but totally worth it!
Things I Would Have ChangedNeeds a fitted gun case & a more ambidextrous design. Lefty shooter will have a problem due to the magazine location.
What Others Should KnowMy FX impact was missing the factory moderator. With just one phone call, Pyramid air got in touch with FX and another moderator was hipped to me directly from FX. I can't say enough good things about both companies, buy with confidence.
The power is there and a bit of an over kill for a squirrel. Don't ask me how I know. Accuracy at 50 yards and beyond is great. Lighter than my Sumatra and the trigger feels like a pound or less. Moderator ready and slug loving.
Things I Would Have ChangedNothing!!!
What Others Should KnowRight now as I type this there is not a slug liner on the market for it nor are there any FX slugs for it on the market. This is a mistake on FX part because it is what we have been waiting on. Some of us have had this gun for over 6 months. Thank god for NSA because if not for them we would not have slugs to sling out of this thing
FX is the highest quality Airgun I have eve shit. I have many guns nothing compares It is lightweight extremely accurate and built to perfection If you can get one by all means do
Things I Would Have ChangedNothing
Every thing. I gut Ronin modurator and extention. I can use it inside the hoise even if people sre sleeping. I is a quiet level one quieter than my 0.22 airguns.
Things I Would Have ChangedNothing.
What Others Should KnowBuy the moderator Ronin and extention from Donny and you can use it in your backyard. I had 2 prior airguns .357 with moderators and I sold both for less than40% of the prices because they were too loud and my neighbors were not comfortable. But now I can use it at night and and nobody will get bothered.
