Co-witness w/ Aimpoint Comp M4

[BRANDON7766]

Woud I need some sort of riser etc or does the rail that comes with the Comp M4 have what is needed. I am using a DD M4 upper.

thanks

What kind of co-witness do you want? The factory QRP2 mount and spacer will give you absolute co-witness with the A2 front sight. For lower 1/3 co-witness you'll need a different mount.
