An extremely compact rearsight, with a built-in anti-glare tube. Designed to be used with the Centra 1.8 Crystal Iris (available separately), the combination is as shown and provides an uncluttered field of vision, with the increased peripheral vision helping standing shooters to reduce sway, and providing a much improved view of the windflags.
It features adjusting screws on both sides for horizontal movement, and a thumbwheel on top for vertical adjustment.
This variant features the SR rapid-fix system which allows for faster change-overs - particularly important for 3P finals!
