Hey guys quick question.
I think I'm gonna pick up the compm3 and like the bobro 150/180 mounts.
I just don't know what one to get. I don't have iron sights may put flip up sights on in the future but never really plan on using the compM3 and flip ups together.
So I guess the question is what bobro mount should I go with what are the different purpose between the 150 and 180?
I do plan to put a 3x mag behind it if that accounts for anything.
Thanks!

The only real difference between the two is height. the 150 offers an absolute co-witness whereas the 180 offers a lower 1/3rd co-witness.

If you are planning on using a magnifier later, then I would go with the 180. This will make it easier to mount a folding buis under the magnifier later on.
