Well I'm a jump in with both feet kind of guy, all three of these liners shoot lights out with no orings. .22 slug A, .25 superior, and .30 slug A.

Fully coated with a good adhesive with no dry spots. No I haven't shot them yet but I'd expect the same accuracy. 

Big thanks to Newman at 910 airgun for getting them to me so fast.

Its done to make the barrel more rigid.....

I am not trying to be a difficult and a ss but why would you think a rigid liner would be better vs floating/wobbling/flexing/vibrating you call it? Is it proven FX would doit on the production line? just asking...

Again, I really like the look and also I can see adds to a convenience.

Well ask Ernest then? It's been proven both a full thickness barrel and a liner can be accurate. I wanted to do this so I did it.

I have an STX liner for now because still over 10 tins of JSB's in my drawers. Waiting for some parts from AGS and when they notify me all my order is on a pile I will grab one superior liner as well. I will be back to you for education how did you bond the CF to a steel. THX

instead of using such a carbon sleeve you just could fill up the room between liner and housing with 2k epoxy

Haha you do it and let me know how it goes. 👌

So Glem, is it pre glued or is there other products needed to wrap the liners.

No they didn't come pre-glued, and it's a CF tube that slides over not a wrap. I used a construction adhesive that I've had great success with.

They're still accurate, I didn't ruin them! Went out for a rainy rat session Friday night with Carlo and it shot very well in .22, then a bit later on sighted it in .30 as we we're gonna try and get a yote too but no dice and was miserable hard rain. Didn't spot any negatives in accuracy and was like a laser beam with 20.2 NSA will probably be my new rat round as they cycle nice in the SS mags and are relatively cheap. Will help with those 80m shots when zeroed at 35m or so with the flatter trajectory.

Carlo is only around a Weekend a Month so gotta make hay rain or shine.

Brought my zero closer to zero on both calibers also, might be coincidence.

Had to do some umbrella taping to keep the works dryish, it's definitely a rain or shine gun for me.

Curious, Glem. I’ve got the liners from Ernest. I promised him a full report once I got my shoulder sling off, but I’m curious if testing could be done with the cf liner treatment just slipped on, and not epoxied. If I taped off the ends of the cf tubing onto the liners, for a temporary hold, what possibly could be say, different than an all out epoxy job?

I did mine a good 4 months ago.

@ Bigragu. I don't think you'd get the full benefits without bonding to the liner as your not making two separate pieces of material as one solid piece. Still minute movement between the liner and carbon tube.

@ Intenseaty. When i I did mine i made the fit so the tubing would just slide over the liner and slide down under its own weight. Not hammered on and not sloppy. I used jb weld 4000 psi two part 5 minute epoxy.
