Picked up a Sig Sauer 5.56 from Blackwing yesterday. Came with magpul furniture and flip up rear sight with a fixed front sight for about $1100. Definitely spent more than i was wanting to but im very happy with it. Its the caliber i wanted, from a reputable company with the features and expand-ability that was i was looking for. At first i didn't like the magpul grip b/c i thought it was just fixed with no way to add a vertical grip or light but i guess they have their own system to its possible to add other stuff later.
I called, shopped around for a few weeks, as of yesterday Vance's didn't have anything worth while under a grand, everything i did find under a grand i wasn't really happy with. The only AR under a grand at Blackwing was pretty bare .223, no sights, no rail, fixed butt stock i think that was a bushmaster.
