I already share in r/hanklight https://www.reddit.com/r/Hanklights/s/FONcCgC4CV but I think I wil also share here.
I have succesfully fit 17mm convoy TIR into KR1AA.
It can be done by sanding a little bit of TIR base and add spacer between body and bezel.
Beam comparison also included. Standard TIR vs Bead 20° TIR

Sweet! I had a similar fix with my FC11C recently, works like a charm now after I sanded the TIR down a bit.
