FX Impact Compact .25 PCP Powerhouse – Initial Findings

In the last post, I covered my journey leading up to the purchase and arrival of the FX Impact Mk.2 Compact. The rifle performed beautifully right out of the box. The trigger was definitely very nice and the action was smooth.

For the price though,I did find some features, or lack thereof, annoying and ranked them in order from biggest pet peeve to the least:

  1. There is no “cocked” indicator and it will let you double-cock the rifle thus loading/stacking multiple pellets on top of one another. I have learned over time to carefully pay attention to the feel of the cocking handle about a 1/4-1/3rd as the absence of the spring compressing tells me it is already loaded. I also try to make sure I put the rifle immediately on safe as another flag. While mistakenly double-cocking the rifle has decreased, it still happens. When it does, I open the bolt, remove the magazine and use a cleaning rod to push them out. Come on FX, my $800 Gladius disengaged the cocking lever once cocked to avoid that user error. This my biggest beef.
  2. The owner’s manual is a bit vague. It is concerning that it says changing the power wheel when charged will damage it and void the warranty. WTF. Maybe you should fix your design instead. Putting the blame on the operator is a total cop out. Dear FX, I reached out to your customer service group asking what the power level numbers and letters correspond to with no answer.
  3. The distance from the Foster high pressure quick connect fitting to the trigger guard so long that the purchaser must go out and buy an extended length female fitting? If you find your common length female fitting below human reach once it clicks into place, remove the screws from the trigger guard, remove it, remove your coupler from the rifle and then promptly order a longer one. Tony sent one with my rifle that I wasn’t sure I would need – turns out I sure did. I later ordered an even longer knurled one that DonnyFL sells. Not the end of the world by any means but it is annoying.
  4. Your decocking feature would be nice except it leaves the pellet in the chamber and unless you pull the magazine too and remember that one is in there and shoot it before re-installing the magazine, you will double stack pellets. I’d tell anyone reading this to shoot a pellet into the ground or any other suitable stopping surface vs. using the decocker.

That’s it in terms of things I dont like and I had time to reflect on this list. All in all, it’s a pretty wicked PCP air rifle.

The DonnyFL “FX” Moderator

DonnyFL makes quality sound moderators exclusively for airguns in Oviedo, Florida. While the FX moderator that Tony included did reduce the sound levels, it wasn’t enough. I had a “Ronin” series moderator that could absorb more gas and reduce sound levels even further so I installed it on the special adapter that was already on the rifle. It definitely reduced the sound even further but was still too loud. I added in the 6″ extension and it was quieter but I want even more. I plan to purchase their biggest moderator the “Sumo” and will post about that later. So it’s not really a knock on the FX series moderator but I would tell you to at least get a Ronin of the right caliber and the correct adapter to install it.

This is the DonnyFL Ronin moderator on the left of the seam just above the end cap that is keeping the assembly from rolling. On the right is the optional extension that lengthens the moderator. It was a cheap experiment to see if ot lowered the sound level when firing and it did. I am betting the Sumo will lower it further because the extension is just a hollow tube that serves as one large expansion chamber whereas the Sumo is designed to absorb the compressed air blast the whole length.

Element Optics Helix 6-24×50 Scope

Element Optics is a sister company to FX and their goal is to make quality scopes for airgunners and even firearms. I will say that the glass is remarkably clear but I will also tell you that one day I got my air rifle out and missed the squirrel I needed to dispatch and then I missed another and another. I set up a target and the impact point had shifted almost 1.5-2″ to the right but it was consistent. My best guess was that I had accidentally turned the non-locking windage adjustment knob quite a bit. How? I have no idea.

It turns out there is a zero stop you can easily adjust to return to zero – I wish I realized this up front. It was my fault for not reading the manual up front. What I should have done was to confirm my zero, set the zero stop and then if I had any question, I could immediately return to zero. Live and learn.

Air Source

In December 2020, I invested in a GX CS3 high pressure air compressor off Amazon and it is still going strong seven months later. I run an inline filter to my 18 cu ft Omega tank and use the tank to fill the Impact Compact – I still put a filter between the tank and the airgun just to be safe – quick connects make the plumbing and moving things around real easy – I use all Air Ventury quick connects to avoid compatibility problems – I’ve had to swap out a few generic fittings along the way. Click here for various posts about the compressor and tank.

The GX CS3 compressor is geat. Here it is in refillying my Omega 18 cu ft tank. The small blue cylinder in the air lines is a high pressure air filter. I have a bigger one that I need to replace the generic male fitting with one from Air Venturi and once I do, it will be filtering the air for the tank and then the small blue fiter will filter the air from the tank to whatever airgun I am filling.

Some Photos For You

This is the Impact Compact with the DonnyFL Ronin moderator sitting directly in front of it.
Here’s another angle.
Here’s the power adjuster that I still don’t fully understand. “3” seems like a nice middle of the road setting that works on squirrels without a lot of over-penetration at 14 yards. You can also see the trigger – it’s definitely sweet and contributes to the accuracy.

In Summary

Most of my shooting is within 50 feet and the rifle is an absolute tack driver, It will takke a squirrel or rabbit out with no problem. I’m using the JSB 25.39gr pellets and with the excellent trigger, where ever I put the crosshairs the pellet follows. I’m going to stick with this base rifle for a while but I did replace the scope with an ATN X-Sight 4K that I will write about next.
