Bushnell Advance 1x Reflex Site BNIB

I have for sale a Bushnell Advance reflex site, still factory sealed in the original box. The following description is direct from the Bushnell website.

The Bushnell® Advance™ is a micro reflex red dot sight small enough to fit on a pistol,. It projects a 5-MOA dot through waterproof, fogproof and shockproof optics.The Advance™ is the smallest, lightest red dot in the AR Optics family, and is ideal for close-quarter scenarios.

I didn't fully understand what this site was when I first got it, and don't have an appropriate use for it, so off it goes. Anywhere in stock is selling for $240-300, so I am looking for $160. I will also entertain trade offers.
