I had been running my Knights Armament 30mm one piece mount with not problem till I picked up the rings I finally settled on for my A5M.
I now have TPS TRS #30580 low .925" rings TSR 30mm low 7075 Aluminum - TPS Products
They fit great, tighten up tight, and zero issues out of them, haven't run into a problem with the factory rail on the A5M.
