Default Which Riser for 1/3 Co-Witness?

I'm thinking of getting this: http://www.amazon.com/UTG-Green-Inte...=26U6GLZ6Y70RA

Which UTG riser would I need to make it lower 1/3 co-witness with the MBUS flip up sights?

Thanks!

Probably this one, I think it is the 1/3 co witness one.

I have the the other UTG for true co witness for my new Primary Arms Micro red dot that came yesterday.

Your UTG scope looks about the same height as my PA.

PM me I have a new UTG #RS10S3
I bought it for my red dot but did not need it because the red dot came with the tall mount.
Never opened

Thanks

.5in riser

Suggest looking at a red dot that is designed for an AR platform with riser. Check out Primary Arms.

It is a guess, until you mount the optic. Best way is to buy it and then using something under the mount, build it up to the height you want, and measure the build up. That the riser height you need. Depending on the optic and sights, I have used from 1/2 inch to 1 inch high risers.
