Clear, transparent plexiglass protection plate for EoTech type holosight and red dot sights. Compatible with 551/552/553/XPS style sights, among others.
Please note that the protective plate may crack if hit by a bullet. The purpose of the protective plate is to absorb a hit that would otherwise hit the sight lens. The possibility of cracking increases in cold weather, when the plexiglass plate takes multiple hits (the structure weakens), and when hit from close range.
