Speed Bead System Both the target and the red dot remain in focus. Optics and their position on the sight plane eliminate the need for perfect left/right, up/down head position for an accurate shot. Mount puts the center of the optic directly in line with the ventilated rib. Three and one half to four and one half inches of eye relief.
For : Remington 1100/1187
