Anyone use a roll pin for gas bushing?

Thanks! Mine is throwing them about 18-20''. I was hoping a smaller bushing would help recoil and accuracy. It is a 580 with pencil barrel. Yesterday a friend came over with a DD AR and after shooting both, we could tell the mini had more recoil. My mini held it own at 100yards shooting horn any v-max.

Thanks for the advice. I think I should just order some different size pills and test them out.
