This is a Yankee Hill Machine EOTech riser, EOTech 4x clone magnifier and a real EOTech flip-to-side mount (mfg by Samson). Glass is clear and works great. The stock mounts the magnifier clones come with are crap. Mine broke on the first range trip. The factory EOTech FTS mount (mfg by Samson) cost $300+ but works great and is really the only mount that you can get for the bigger magnifier. This works perfect with an EOTech, as the magifier makes the view through the tube square to match. I have almost $500 in this setup. I no longer need it, as I sold my EOTech. $375 + shipping. I accept PayPal + 3%, USPS MO, or cash. Can meet FTF in the Tacoma/Fort Lewis area.
