Competition shooters are always looking for that "little something" that will save even a fraction of a second. The Black Mamba-X and its multiple hole mounting locations will do just that.
Keeping the red dot mounted as low to the bore-axis as possible makes for faster sight acquisition and there is no better way to do that than to mount the red dot directly to the upper. The Black Mamba-X is built using our LLV-4X 4.5" Competition Upper that features an integrally machined universal red dot mount.
