OK I'm trying to get some advice and it seems I can't seem to get a answer.
I bought a truglo red dot. It was cheap. I want to put this on my cmmg 22lr. The red dot has a integrated weaver style mount. From what I read weaver mounts can be mounted on a picatinney rail but not the other way around.
The upper has a flattop pic. Rail with a A2 front sight.
I want to absolute co-witness with my red dot. I assume I need a riser to do this. Not sure if I need a half inch or inch riser.
The red dot seems to be high already.
If I do need a riser I'm thinking about getting this riser

Or another brand like a utg. Is this the right size height mount?
