UPDATE: All three of my 407CX2 are sold. They went quickly on eBay. I just have the 509T left, which of course is probably the best model to have.
Original message:
Just yesterday I had three Holosun 407C X2 (RED dot) units. But two sold unexpectedly, so I have one left. I also have one Holosun 509TRDX2. They are new, never mounted, sealed screws, perfect shape, you would be able to register them on the Holosun site for warranty purposes, and MA state tax must be collected, you would be given a receipt. With tax included, I can do $210 for the 407. And with tax included, I can do $410 for the 509. I am not a gun dealer, nor am I an official Holosun dealer. I have no room to negotiate further. But it must be cash, near Newton, MA, or possibly at the Hopkinton Sportsmen's Club. Of course, you can gently inspect the item to confirm its condition but cannot place any wear on it until you own it. And of course I can send photographs upon request. I think I have the 509 listed for sale on this site, not sure how much I put on the listing, but of course you can have whichever is LOWER (this post or the other). These sometimes sit around for a while, and other times sell quickly. It could sell at any time without notice. Thanks for your interest.
