Thoughts on AR15 to22LR conversion kit

I picked one up years ago on the 50% off bin. CMMG bravo I think. I bought a 10.5 upper on sale, as a dedicated set up I can throw on my PSA lower. Works well, eats anything “semi auto” rated, I use the cheap automatch ammo. I would like to set up a lower for this from the jackyl since the CMMG doesn’t need the buffer tube. I’m still reading and researching if it will fit. I’m hoping someone else here has done it?
