FX carbon fiber barrel sleeves

I'd like to do side by side 50 yard - 100 yard comparisons I think that would be super cool to see . If I can get further I will just depends on where I go and if I have time to go down south lol. But ill post what my results :). SPAW have the carbon sleeves that you don't have to Epoxy? I thought I saw FX came out with one that doesnt need to be glued on.

Yes the ones SPAW sells are advertised as not having to be glued on, I think i’ll try and purchase one here sooner than later, i’ll try to remember to do a before and after at 50 and 100. That’s a great idea.
