co-witness height difference

Postby m00p3y on Fri Dec 09, 2011 8:48 am

What is the height difference between absolute and lower 1/3 co-witness? Have a micro red dot mounted at lower 1/3 and the 3X magnifier I just bought is at absolute, what size slotted riser should I get to bring it to lower 1/3?

The difference in height can very between companies, but it usually is about .3''-.35''. With that being said, you might be better off with getting a new ring.mount for the magnifier. Some actually come with a spacer, such as the G23. Let me know what setup you have and I'll see what there is out there.

I am using a Daniel Defense 1/3 co-witness micro mount, and just got in a vortex 3X magnifier with an absolute co-witness swing mount.

Have a Vortex SPARC on the DD mount.
