I have a new Vortex Defender ST 3MOA dot with everything it comes with from the factory (picatinny mount, DP to MOS adapter plate, screws, manual, tool, etc. Battery installed to test unit but not mounted. I am looking to swap it for a 3 or 6 moa optic that utilizes the RMR mounting footprint. This Vortex used a delta point pro footprint. Something like a Holosun 407c or 507c, swampfox liberty 2 or justice 2, etc. I do not want a super cheap Amazon/eBay optic like a zulisy, CVlife, etc. I do expect your offering to be in very good to like new shape as mine is.
