The Butler Creek Sidewinder Scope Cover features pattented zero clearance technology that was designed for optics that are paired with magnifiers or night vision devices. Throw conventional out the window with these combo optics due to the low clearance between the pairing. The zero clearance design opens the sidewinder on two planes in one fluid motion, first to the side and then towards the optic body. This innovative product will keep your tactical optics free of obstruction while allowing lightning fast access to the optic, getting you on target faster than any other option.
