More options might come up on optics warehouse if you search by rail size and scope diameter
But its +1 for BKL from me
Well BKL would of been my go to also ((I have them on my Daystate).
But when i read about BSAs rail size of 13 MM looking around very very few vendors had a 13 MM rail size for their mounts.
You are saying the rail size on the CLX pro is not 13 MM ..???
