I have a Bushnell HoloSight new and still in the box with batteries included and fits a standard flat top AR or can be used on an AK or any rifle or shotgun with a Weaver mount. This is the double AA battery version that runs for so long. Has the production date of August 2004 on it so they just built it. This is the same design as the EOTECH that everyone raves about so much. This one like the EOTECH is also waterproof and fog proof and mounts on any Weaver base. Has 20 levels of brightness intensity. I am asking $265 shipped in the CONUS or will trade for a nice M39 plus cash. Please do not post. Please email me at firstname.lastname@example.org and first I will take it offer gets it. Thanks.
