FX CF Sleeve?

Short answer is, it won't hurt. I've got two Mavs, a 600mm (.22) and a 700mm (.25) One is glued, epoxy, one is 'floating'. Zero difference in efficiency, but....better than a plain soda straw. As long as it's a really good slip fit it'll stabilize the soda straw. AND it's REALLY sensitive to how loose or tight the lock nut is.

i think they help on 600mm + length barrels.
you may want to index the liner there is a few videos on u tube really easy and you get your best accuracy by doing so.
the liner lock nut i turn in with my fingers and just snug with a wrench 1/8-1/4 turn.
Mine is a 600mm and I’ve read 1/16 to 1/4, I’ll finger tight and do 1/8 if it feels not snug I’ll go another 1/8.

You’ve always helped me out, I just didn’t want to somehow make it worse by not tightening it correctly.
