ADM Comp M4s Mount?

Anyone running one? How well does it return to zero? Have you had issues with the spring breaking in the locking mechanism? Any complaints?

Does the SOCOM riser actually make true lower 1/3rd cowitness?

Thanks In advanced, John

The socom riser is true 1/3d cowitness, I ran one on my m4s for about a year, beat the shit out of it, returned to within a click on multiple occasions.

Thanks, thats good to know. I have had Bobro and Larue and while I liked them both the ADM is considerable cheaper than the other two. I am deciding between another Bobro and a ADM.
