Don't want your precious holo sight shot damaged? This one-piece CNC light plastic shield offers the best protection for your very valuable (and thus, expensive) holo sights. For those of you who own a real EO-Tech scope, this protector also fits the real the real thing, in which case you are protecting a VERY EXPENSIVE piece of professional equipment.
The shape is specifically designed to fit onto Hurricane / AABB / G&P sights, repeated tests have been done to verify the strength to be able to withstand normal airsoft guns' power; although, the main credit goes to the optical work: thanks to Guns Modify's latest technology, it gives no distortion to the viewer unlike most other sight protectors.
