Stingray Mk5 Prototype M16A1 Laser sight - One of a kind?

Description

9/6/24 - This is an excellent example of a Stingray MK5 Laser sight for the M16A1 built by Hydra Systems International Inc. in the 1980's. Hydra Systems International appears to have gone defunct in the late 1980's. All we have found in our research on this item is one patent lawsuit against Hydra Systems. This piece might be a one of kind piece as we could not find any examples of this item in our research. The sight itself is in excellent condition, and comes with two original batteries and the charger. The batteries do show signs that might indicate that they are no longer good. We would recommend not trying to charge these batteries, as they could cause further damage to them. That being said with the proper time and skill this sight might be able to function again. There are is no physical damage to the sighting system, and the case for the item has no dents. Additionally the sight comes with it's original manual and warranty cards.
