Has anyone had problems with their carbon fiber sleeve fitting. It fits over the liner fine, but won't fit into the liner sleeve. I have .22 maverick compact.
Fx Carbon Fiber Sleeve Problems

Yup, same here.
I was about to start this exact thread to see if anyone else is having this problem. M3 Compact .22 for me.
The CF tube is too large diameter to fit in the barrel tube and the liner fits almost loosely, definitely not a tight fit as I was expecting.

I had the same problem. Bought the FX branded carbon liner sleeve for 500mm .22. It fits very snug on the liner but would not slide past the internal threads of the barrel housing. A little trial and error with very light sanding allowed me to make a perfect fit. Only problem now is, it’s so snug I can’t pull it out from the muzzle end to index my liner without taking off the transfer port end.

Yeah, not sure what they were thinking.
I guess I will sand mine down, though I am sure it will effect it somewhat since I won't be able to hand sand it as true as a mandrel formed CF tube is naturally.
Kinda disappointed

Well, I sanded mine down and it fits (barely), but I"ll probably have to try to take it out again and glue in the liner. The liner is way too loose as you can wiggle the liner up and down, side to side when it is fully inserted in the cf tube. The liner has very noticeable play.
Dimensionally off on both the outside and inside. Sure thought they would be better than that!

It was only oversized very slightly so I didn’t want to risk jamming it in. I think I used 600 grit sandpaper and lightly sanded the tight spots as it wasn’t perfect from the factory. I don’t think they can form the carbon fiber to fit exact tolerances without hand fitting. Better a little bigger than too small.

I have personally Received two of the FX carbon sleeves one is a 600MM .22 and the other is a 700MM .25 both fit perfectly for me. They are both significantly better than the previous ones I had purchased before FX took over them.

Has anyone used the carbon sleeve on a STX .22 heavy? My heavy barrel won’t fit too tight. My standard barrel slides right in.

It isn't uncommon to have to do a little sanding on the carbon tubes, FX or other companies. The tolerances are a bit harder to get spot on than with metal. All it takes is .001 for something not to fit. Here's the stuff that has worked for me: For sanding the OD, chuck the CF in a drill while sanding and you should be able to keep the sanding pretty even. For the ID of the CF, use a dowel with sandpaper on the end chucked into a drill while moving the dowel in and out the full length of the CF tube. That will allow you to open it up slightly to get the liner to fit, if it is too tight to get in the CF tube. If the liner fits loosely, then definitely glue it with some 2 part epoxy. Do not use 5 minute epoxy, or you could end up with a disaster and a liner that is half fitted, lol. After you epoxy it, make sure there isn't any excess at the ends and install it in the barrel assembly before it cures. That will make sure the liner is centered. Let it sit for 24 hours out of the gun(laying horizontally), then get to shooting. I hope that helps.

I have the FX version on the 700mm. The STX is tight. It is an absolute perfect fit that has no movement at all. The standard is definitely not like that. It does not have any play in it, but it would slide fairly freely.

My liner fit in the sleeve just right nice and snug but still removable. Can you say perfect?
The problem I had was the CF sleeve did not fit in the, old early Impact-X, barrel sleeve. So, after running some Scotch Bright up and down inside of the barrel sleeve twenty or thirty times to make sure it was cleaned out good I started using the Scotch Bright on the outside of the CF sleeve. When it still didn't fit I resorted to putting it in my mini lathe, like Rallyshark said a drill would werq, and used some 400 grit sand paper on it. It only took a few passes back and forth before it fit in the barrel liner snugly. But I had to tap it in, the last inch or so, past the threads with an eight mm 1/4 inch deep well socket and a small hammer. So, it fits good.
Doubt this will do much of anything, as the gun already shoots lights out, as I have already done a barrel tension mod on it so it is very stable. I also had my o-rings stabilized so they were not going anywhere either so, why I went through all of this trouble I have no clue. Possibly it will be a slight bit more stable now though?
Can you say Addiction? ;^)
Just an after thought there was really nothing wrong with the CF sleeve cuz as I looked down the inside of the old barrel sleeve I could see everything was as not smooth and perfect as it could be.

A tight fit which has to be hand sanded to fit is actually the best you can get for maximum rigidity. The one I bought from FX has an OD of 11.75 mm…. So now there is a 0.25mm gap inbetween the CF sleeve and the steel outer sleeve which sucks.

I recently changed to using Gorrilla glue for bonding tubes. This stuff works great , especially for loose fitting parts. Reason being is it expands to fill voids . Unlike locktite bearing retainer I was using previously. Method I use ( as per instructions on bottle) I use a damp cloth to wipe down the inner tube ( liner ) then apply a light coat of glue. I’ll spin the inner tube by hand while feeding into the outer , so that the glue is evenly spread. Once completely inserted I wipe off any excess and clamp the tube at either end so it doesn’t move. It only takes a few hours to cure and no need for heating or baking the parts. Great stuff.
As mentioned wear a mask when sanding down the carbon fiber tubing , the resins are highly toxic and the particles will destroy your lungs. I go even further by wearing latex gloves.

I thought my CF sleeve was too long until I realized that one of the three o-rings on the barrel got left in shroud preventing the sleeve from going all the way in. Duh.

Did you use the Gorilla 2 parts epoxy or the one that expands with moisture? I think it is primarily for wood work.

I purchased 2 of them. Haven't tried the 700mm .22 yet but my 500mm .177 won't fit as it won't get passed the threads. Ill try to sand and see if that works! Thanks everyone...

Hi guys, I bought FX carbon sleeve for my 700 mm .22 liner and one end of the sleeve is not perpendicular to sleeve axis. Do you think it might bother with something? Can I use such sleeve without any worries? Or shall I rather claim it to supplier?
