EOTech 517 A65 Holo Sight Raised 7mm BLK

EOTech 517 Holographic Red Dot Sight 517.A65

EOTech 517 Holographic Red Dot Sight with Raised 7mm Base was developed to optimize the functionality of the Holographic Weapon Sight. The buttons have been moved from the back to the left side for instant access, allowing a magnifier or a BUIS to fit closely to the tactical sight body. This button position allows the shooter to operate the EOTech 517 function switches easier than before. Additionally, a portion of the front base has been raised 7mm to allow the sight to mount over standard handguards found on many M-4 or M-16 style weapons platforms.
