The SideWinder optic cover is the latest product from Butler Creek. When normal flip caps require too much space to use, the SideWinder's patented Dual Axis Zero Clearance design rotates up to the side before folding back out of the way to provide 100% unobstructed viewing.
These covers are field tested and built to function in a wide temperature range offering the ultimate protection for professional operators and marksmen in the field or during transport.
