The FX hollow can you got with the gun actually does a decent job. Also “best” depends on what you want it to do. As quiet as possible? Light? Short? I like the STO Falx on mine. IA 1250 and Donny Yoko are quieter but also heavier.
As for POI shift, it’s an impact… and tensioner/clamp aren’t available for the m4 yet (thanks for the ever so slight changes, FX…) so it is what it is at this point, don’t bang the gun around too much I guess
personally I don’t like barrel bands since they’re not really affixed and just a bandaid. Is your POI shifting even without moving the gun around between sessions?

I second the STO Falx.
I found installing the FX Carbon Fiber Barrel Sleeve helps with the POI change.

I have the 22 cal m4 and the factory can is great .As for poi shift I have none but i installed the carbon fiber liner right off . I can`t say for sure that it made the poi diff or not !

The CF sleeve definitely helps! IMHO should first/in addition be figured whether it’s barrel induced POI shift as opposite, e.g., wonky tune, sticky valve rod and 15-20 warmup shots with different POI or whatever else is out there. Hence the question as to whether the shift happens even if the gun isn’t moved around.

Found the same thing now my drs is different story that just doesn't ever shift even if you pick it up by the barrel just have regular 1 in 16 slug liner on orings in the drs

I have switched all of my guns except one to Sonus moderators. Very happy with them. One day I will change the one Impact Air one out as well.
As others have suggested put a CF sleeve on the barrel as the first attempt to clear up POI shift.

You would think by now that CF sleeve would be factory installed. God forbid they miss that profit opportunity I guess.

CF Sleeve and a tensioner of some kind. If your Impact came with the newer front support block with the clamp all you really need is a spacer to go between that and the shroud.

Chuckar60 were did you buy your Sonus moderator.
I can't find their website.
I did find them on Cape Fear airguns but they didn't have any in-stock.
Thanks

Idaho Air Guns. I was there this afternoon and they had a healthy stock of them. One thing nice about the Sonus is that you can change the caliber.

On my 22 sniper I tested all 5 moderators I had. This included the Donny small and large with sections on them and the impulse a similar model to the Donny. An older Donny and the one that came with the gun. The best for accuracy with my setup, the one from FX and it really is just about as quiet. I even shot the moderators full length and then would take a section off at a time. It does make a difference.
Now on my drs pro, same process and it like the Impulse with all the pieces attached. Again for accuracy. Of course I also did no moderator and the guns we’re too loud and not as accurate.
so is one the best. Absolutely not. But trying to find the one that works the best on your gun is a time taking process and you have to have the moderators available to you.

Okay every one thanks to every single person here sharing their experiences i spend time tunning and got some tremendous results and very happy with the platform ,the reason i ask what moderator was the best is because i thought the factory one was the reason for poi change during the groups,I could get done a great tune as you can see in the pictures but poi issues never went away, i order a sleeve and shroud tensioner to see if i can g install it some how.
