The Firing Line Forums - View Single Post - Dual-apperture BUIS for Co-witness on AR15

I have a set of polymer Magpul MBUS sights (front and rear) on one AR. They will co-witness fine with most red dot sights that come with risers intended to position for co-witness.

I agree with zukiphile that even the smaller aperture on the Magpul MBUS rear sight is bigger than I would like. I don't know if the same is true of the metal Magpul MBUS Pro or not. But I have the sights on only as a backup to a SIG Romeo 5 or a Vortex Spitfire 1X prism scope. If I wanted to try to do precision shooting with "iron" sights I would probably use something better than the polymer Magpul MBUS set. But they are light and work fine for backup.
