Questions & Answers
Heard fastfire shares same footprint as vortex venom. Can you mount together and confirm 1/3 co-witness on AR platform and cutout for windage adj.? Expert Answer

While they do use the same foot print this just means the screws are placed in the same position. Please be aware that just because they have the same screw mounting pattern this does not mean they are the same size. The Vortex Venom and Burris Fast Fire have different dimensions. The Venom is slightly bigger than the Burris Fast Fire, so it is not recommended for use in enclosed mounts like the AR-F3.
