New impact dependability

I don’t think you’re nuts, I’d probably feel the same way if that happened. I got a new .25 from Ken in April. I’ve put 3000 pellets and slugs at 140 bar through it so far. Ken put the Delrin C3 in for me as well as the probe and valve seat upgrades he offers. 

I’ve had zero issues with it and I’m still amazed at the accuracy and reliable workings of these things. My version is 700mm. I find the compact version very attractive also and may order a short barrel for mine in .22cal at some time. Best wishes. 

Its time for a MARK111 or is it 4, or even IV, and with this model, instead of MORE (power) BIGGER (calibre) or pretty colours, RELIABILITY RELIABILITY RELIABILITY.

Ooh and a 580cc 600mm combo, where the shroud an bottle end Just about at the same point. 33"?.

More cake anyone

How much do you shoot? I have well over 6000 pellets through my MKII PP 22. No problems yet.

I sold my impacts due to unreliability and all the hyped up nonsense that goes on with these impacts! With so many people trying to capitalize off the platform I can't keep up with it. I rather have something simple with less gadgets. There's been a post for years everyday about someone with a problem with a impact. 

I was apprehensive about reliability and a bit intimidated about being able to tune it properly but took the leap and got a .22 MkII 600mm. I've run about 2000 pellets through and I'm nearing the same number of slugs without an issue. I'm sure I'd be disappointed if I went through what you've experienced. Even though they are quite different guns I was torn between the MkII and the Leshy 2. I went with the MkII with the logic that the Edgun would have teething problems and the FX was a gen 2 with the bugs sorted out. I'm sure the Leshy 2 will be a fine gun but after watching Steve's video of the FX Factory tour it seemed to me the level of commitment was definitely alive and well at FX and I gave it a go. I'm very glad I did! I shoot almost every day at 50 and 100 yds and the accuracy across pellets and NSA slugs is beyond my expectations. These are NSA 31.2 at 100 yds. 

Keyman, If they could find a way to fit a 580cc bottle and a 600mm barrel on to a wildcat, that would work for me.

but an Impact that had those and had a rep for durability would also tick most boxes. L/H would seal the deal.

good luck

The mk2 with power plenum does not have a rubber C-3 bumper anymore. It has a delrin bushing. So what used to be fix on the old models have it stock now.

Also the valve spring is now on the outside (oposite side) of the valve rod, which means the threads on the valvestop does not have to be pulled as much as on the old system. 

Three years ago I bought a used Mk 1 Impact .25 that was 6 months old. As if by magic, the reg started leaking on the 4th day after I bought it. Ernest Rowe replaced the delrin regulator body and it was trouble free for 3 years. In February I sold the Mk I and bought a Mk II PP .25 in April from SPAW with transfer port mod and Saber skeleton stock. The improvements from MK I to II are too numerous to mention. But the changes have transformed the Impact from an innovative PCP into a great one.

Considering how many Impacts are sold compared to other brands and that buyers with problems are more vocal than the majority of satisfied buyers, it isn't surprising that there are some who might assume this is a trouble prone design. It's not. I love the Impact Mk II and recommend it. My guess is that it's the best selling high end PCP on the market. If imitation is the sincerest form of flattery, then consider that Daystate is coming out with the Delta Wolf. Their Pulsar and Renegade models are now discounted and will probably be dropped from production due to lagging sales to the Impact.

Just to clarify, I am no FX fan boy. I have a local friend who owns lots of the older FX's and I never liked any of them. It seemed that he had more than his share of leaky FX's and I found them much more difficult to service because the designs seem purposely complicated for dealer only servicing. Simple o-ring leaks in air cylinders require specialty tools for disassembly, and the reliability wasn't great for the price compared to other PCPs. My first toe in the water purchase was a Streamline .25 with laminated stock. It has been perfect and as accurate as any PCP including the Impact Mk II.

One last observation. I've never been and still am not interested in modular airguns or multi caliber barrel kits. It might be a great marketing and sales tactic for FX, but it's not for me. I'm not interested in multiple caliber overpriced barrel kits. $480 for a barrel, shroud, probe, and magazine that requires multiple settings to be changed? No thank you. Who wants a rifle one day, and a bullpup another on the same receiver? It's a PITA to change the linkages, stocks, settings, etc. If I want two calibers or two different types of PCP, I'll buy two rifles. Most of the time FX promises accessories that don't become available until the PCPs they're made for have been obsoleted by an newer version. Yet it seems to boost sales. Not my cup of tea.

Couldn't agree more. The switch barrel gun in powder burners (Thompson Center, Sako Quad to name a couple) and airguns is a gimmick. If all one wants to do is switch barrels, re-tune, re-sight over and over, those are the guns for you. Me, like you prefer a standalone gun in each caliber, sighted in with my projectile of choice. Pick up the gun and go shoot. There are tinkerers, tweakers and tuners, and there are shooters. I prefer the same cup of tea.

Sorry to hear of your troubles. I just counted my empty .25 pellet tins and it looks like I have near 10,000 rounds through this thing. What a surprise that is! Mostly JSB King 33.95 pellets but probly 3K of that is the NSA slugs mostly 36.2 at 74 fpe. 

My regulator rod was bad, had a flat spot in it, from the factory and I had to replace the C3 on my gen 1 1/2 which was the norm until I made a Delrin unit. Any other problems I had were self imposed as I have been in constant upgrade mode ever since I got the gun. My Hammerseat came loose from the rod once and the threads did not look all that healthy. But I applied some blue locktight and put it back together, thousands of rounds back, and have not had a problem thus far. Installed a Polish Plenum so was able to lower my regulator pressure a few thousand rounds ago. I expect that made it easier on the hammer seat and rod.

I have never done a complete rebuild yet and most of my o-rings with few exceptions are the originals.

I think that FX has done some changes to the weak spots on the original guns and they are a new and even better animal these days. But for those of us with the old stuff they seem to hold together pretty darn good for the amount of shooting some of us do.

Internal Upgrades include

Delrin C-3 bumper

Installed brass hammer spring shim/spacer/weight

Drilled valve seat to 6.1mm

Drilled valve body for Yong Heng plenum

Enlarged and shaped barrel and probe ports

Removed Yong Heng and installed Polish Plenum

Drilled valve adjuster screw, removed old internal and installed new external valve spring

Almost fergot I replaced the four A6 NBR70 washers with NBR90 to stiffen up the barrel a bit.

I had an impact mk2, it didn’t fail and the reg remain stable but it had an issue that I could never resolve. Every time I picked up the gun, the zero would be off, accurate but not on target. Adjust the zero and it would be bob on but the next day (or even a few hours) it would be off again. I tried different scopes, different mods, different barrels and different settings but nothing helped. The zero shift would be random, sometimes high, or low, left or right

I have spoken to other FX impact owners who had the same zero shift problem.

I had no confidence to take the gun out hunting, I could not trust it to do what it was supposed to. My frustrating experience of the impact has put me off buying another FX airgun

Did you ever investigated a temperature shift - effecting on oring material. I've bought the entire list of orings in both NBR70 and NBR90 to have a first aid kit.

At my place the temperature difference between summer/winter is +35C and usually at least 80+% humid and -40C add a windchill... we measure all these in a shade

Did happened to me I finished a tune in my basement late afternoon (off course AC was running like crazy in late July), next mid day outside trying to hit the "x" and just won't find it.

I completely removed the barrel crush nut assembly and replaced it with an engineered solution, it was better but shift would still occur, I even machined up a LW barrel blank and fitted that but the shift still persisted.. As I say, I have spoken to other impact owners and this seems to be a frequent anomaly.

As much as I wanted to like the impact, the more I used it, the more I hated it and it had to go!
