Looking to build a varmint gun for coyote's. Here's what I'm planning on getting unless somebody can tell me something better. Here's the link: http://www.model1sales.com/index.cfm?fuseaction=category.display&category_id=263 It's going on a RRA lower with a 2 stage trigger. The reason I'm on here is this upper is what I'm looking for but so far the only place I've really seen this is at Model 1 Sales. I checked out PSA and a few others with no luck. Let me know if you know of a better option, I don't care to spend a little money. At this point it looks like I'm gonna end up with more money in glass on top of it than I have in the upper.
