Has anyone ever seen one of there? http://www.gunpartscorp.com/catalog/Detail.aspx?pid=890180&catid=4082
i have not seen those before. i have a set of tech-sights http://tech-sights.com/ (http://tech-sights.com/)
i showed up to my first AS with the factory sights. after two days of shooting, yellowhousejake was nice enough to let me shoot a couple aqt's with his marlin that had the tech sights on it. i was hooked, bought a set for my marlin shortly thereafter. i would highly recommend them.
