I've got a Razor Red dot for sale here with the low rail mount for weaver rails as an extra with it. Picked it up to try out on a hunting rifle but I just don't think it's the deal for me. Mounted it on the rifle but never shot it. Condition is LNIB. I got it on sale and I'll extend the savings to the buyer. MSRP on these bad boys is $500, the weaver mount is an extra $50.
