The EOTech 556 Law Enforcement and Military Night Vision Holographic Red Dot Sight is ideal for use with magnifiers or night vision devices. This sight features the button operation on the side rather than the front making it much more convenient for the user. The base of the sight is designed to clear the delta ring and handguard on M4 style weapons which reduces the amount of rail space needed for mounting.
