SR6 handy sleeve adapter issues

Hey there! Got an sr6 a few months ago and it has been working amazing up to an issue I’ve had the past few times. the sleeve adapter I got along with it simply isn’t staying in place at all any more, and the grooves built into it aren’t stopping it from simply… popping out of the machine at even medium intensity strokes, making the whole thing pretty much unusable.

Has anyone else had this issue, and does anyone have a potential solution to get it to stay in place without gluing it in? I still want to be able to swap out sleeves to try new things. :sob:
