FX Integrated Harmonic Barrel Tuner & FX Carbon Fiber Barrel Liner Sleeves
- Thread starter FX-USA
- Start date
Almost end of June and I am not seeing any FX harmonic tuners or even pricing for them
At least publish the pricing for the harmonic tuner shrouds

Please
1. When do you expect the tuner to be available for a maverick 30 cal
2. When do you expect the maverick 30 cal slug kit to be available also what is the expected price on both
3. When will you be offering the larger divided transfer ports for the 30 cal maverick and the price
thank you in advance

don't think any US dealers have received any yet. Have been told by a couple dealers they should arrive on next container sometime this month.
Hoping tuner shrouds and angle gauge mounts are as well

The liner is supported on both ends by the breech and muzzle liner locks, and the carbon sleeve will support and stiffen the liner between the liner locks and minimize any distortion or buckling of the liner when the muzzle liner lock is tightened and the liner is put into compression even if the carbon sleeve is a sightly loose fit in the barrel housing. From a liner stiffening standpoint, this should work just fine even with a small amount of clearance between the carbon liner sleeve and the barrel housing.
Also, Ernest just restocked the carbon sleeves in his eBay store... Not sure if they're identical to the sleeves that FX is selling in terms of dimensions (Ernest's sleeves previously needed to be bonded to the liners, while FX is claiming their sleeves fit snug over the liners and no adhesive is needed)-- that being said, many of us are still waiting for the FX sleeves while Ernest's are available right now.

Ernest's carbon fiber sleeves are the same as FX. You can either bond to liner for more stiffer or just slide on.

@kiba, thanks for the update on Ernest via EBay. Just got mine before they sell out. I got these for my .25 a few months ago but he had ran out on the .22. Thanks again for the heads-up...

Actually just got this email from Ernest. the sleeves are NOT the same as FX sleeves. The guys in Europe that have received the FX sleeves report they are tight fitting to the liner
below is Ernest's email to me. I still bought one

If that's the case, hopefully I'll receive the sleeve from Ernest and also the preordered FX sleeve from SPAW next week and can compare them dimensionally. Be interesting to see if they're identical or if FX made a few dimensional changes.

Well received my liner from Ernest.
I would not say its not a friction fit but it was close enough that it would NOT slip over the FX liner label on the liner and same if I tried to put the label on the carbon sleeve. Sleeve would not go into the barrel. so not friction but very close none the less. we have 3 to 4 days of Rain but as soon as it clears up and not 15 mph wind I will do accuracy testing to note any improvements

FYI, the carbon sleeve I just received from Ernest had 0.007” diametrical clearance over a .22 superior and a .22 superior heavy liner (.317” liner OD, 0.324” carbon sleeve ID.)
Unlike Ernest’s early production sleeves that weren’t quite long enough for the 700mm liners and left a couple inches of unsleeved liner, the new ones are full length for 700mm liners and only about .125” shorter than the distance between the muzzle and breech end liner locks.
Since the liner will slightly buckle / flex under compression when tightening the liner retaining nut at the muzzle, that small amount of deflection in the liner should easily lock it into the much stiffer carbon fiber sleeve even without bonding them together given only 0.007” clearance-- but I bonded the sleeve to the liner for maximum stiffness so that the adhesive serves as a liquid shim locking the liner into the sleeve in the uninstalled stress free condition. I used EA9394 to bond the sleeve to the liner which is probably overkill (this is not a very demanding application for the adhesive, it’s mostly serving as a liquid shim to take up the slight clearance between the liner and carbon fiber sleeve.)
Since the sleeve was such a good fit over the liner and would scrape most of the epoxy off the liner when sliding it over, not only did I apply epoxy to the liner before sliding the sleeve over as per Ernest’s videos, I also drilled 6x .063” injection holes along the length of the carbon sleeve prior to bonding it and then injected additional epoxy after sliding the sleeve over the liner.
I’ve seen some suggestions to use Loctite 638 retaining compound for bonding the liner to the sleeve, and that is not an adhesive I would recommend for this job as the anerobic Loctite retaining compounds like 609, 638, and 648 are only intended for use between two metallic substrates.
If you choose to bond the sleeve to the liner, you want to use a catalyzed 2-part adhesive that’s not dependent on air exposure or humidity to cure because of the length of the sleeve and the adhesive joint being only exposed at each end.
Is there an accuracy difference between the factory setup of 3 liner to housing o-rings, adding additional liner to housing o-rings, an unbonded carbon fiber liner sleeve, and a bonded carbon fiber liner sleeve? I haven’t done the testing comparing the 4 configurations and can’t say for sure, but given that the liners are rather flexible a bonded carbon fiber sleeve certainly seems like the most rigid and probably the best option. Guess I’ll find out shortly how accuracy with a bonded carbon fiber liner sleeve compares to my previous setup with 7x o-rings between the liner and shroud.
Next up for previously announced M3 accessories, be nice if the angled gauge mounts would ship…
