Has anyone experienced any (-) affects from installing a carbon fiber sleeve?

...on an FX Superior liner?

My liner (currently without a CF sleeve) is shooting really well, but this CF sleeve and harmonic tuner is just sitting here starring me down!

I gained nothing and I returned back to orings.

My CF sleeve was not that tight over the liner and it was loose in the barrel housing. I am not sure if there is any problem with dimensions.

My experience is with .30 cal - two different barrel housings, a couple of liners and three different CF sleeves. The same loose fit.

Smaller cal. may be better. CF sleeve is thicker there.

No negative here just shrunk the groups a tiny bit.. But with the harmonic tuner, I have this thought that it would be great for setting your rifle up for one specific slug or pellet, or favorite..

never thought it was needed if your gun is shooting just fine i had one on a barrel shot it against another with the orings not one bit of differenct its a marketing barrel tuner your gun is shooting 1/2 in groups at 50 then you put that in and start tuning for better groups really maybe high power slug gun thats it

Main thing I notice was my groups moved up 1/2in, but it seems more consistent.

Tried it all.

Barrel tuner, not for me. Reason, I live in a state that the weather changes on a dime and it seemed to have an impact on my tuner. I feel it accentuated the weather shift. I don't have the patience to go through that much ammo to retune when the weather will significantly change the next day.

Cf liner, like it and it helped with barrel droop. Didn't have an extremely noticeable impact to accuracy.

The thing I like the most that I added was the barrel holder front support. Definitely helps with high power slug tunes.

Essentially, no. 

Desired effects can be obtained through many avenues. No need for any of these if your gun already shoots well, but they can be nice to have.

I have put one on 2 FX Crown barrels. One, on an older .30 extendable shroud unit, and another on a 500mm .22 superlight barrel (fixed shroud)

I noticed a big difference on the 500mm .22. The gun is very consistent with it's POI across a variety of projectiles and power levels. Where my other superlight barrel will see large shifts in POI depending on projectile and speed, this one is way more consistent.

What this translates to is a gun that is easier to tune, and also a gun that is less picky with ammo. I do also use a normal superior liner, and I know this helps as well. I can shoot slugs or pellets extremely well with it.

My liner was very tight, and I also epoxied it at full length. Though, it is segmented and spaced for the shroud spacers and the jamb nut. I applied epoxy, asembled the barrel, and let it cure like that, so the cure would occur with the liner in it's ideal position in the shroud.

on my Crown .25 cal, 700 mm barrel shooting pellets, no gain.

Same rifle, .177, seemed to help. Still quantifying, but just thinking something helps... can help?

I put the carbon sleeve and integrated barrel tuner on at the same point, on a M3 22 700mm barrel. I shot at 30 yards, which is what PJ recommended in a video for 22. After the final tune the rifle shot better groups. Sure you can tune the way we have been doing it and get the same results, but I like having more tools in my toolkit. I am including a photo of my targets from tuning. Number 10 group top left by the number 1 was 0.2565 for five shots.

I would try it unless you got your gun shooting slugs. I have one glue in sleeve with Anaerobic rtv sealant and one not glued. Both shooting great. Barrel tuner and sleeve both work for me.

Zero negative affect on the sleeves but not enough time on the tuner to find any negative affects. In theory no negative affect besides it’s kinda heavy. 

 

[Mg616]

No issues. 2 barrels, both showed improved groups. 177 500mm, .25 700mm.

Easier to swap out liners, peace of mind not worrying whether your o-rings moved.

 

[Bobwire]

No difference for me.
