The EOTech 517 Law Enforcement and Military Holographic Red Dot Sight is designed for optimum functionality. For easier operation, the buttons have been moved to the left side for immediate access. This allows for a magnifier or iron sights to be positioned close to the sight body. In addition to this, a portion of the front base has been raised to fit over the standard hand guards found on many AR-15 type weapons. Making this sight even more convenient is the use of normal AA alkaline batteries (lithium AA or rechargeable AA batteries can also be used). The EOTech 517 is ideal for everything from tactical use to plinking at the range.
