I was planning on building an AR and while browsing forums for parts, I came across this rifle pretty much built to what I wanted, so picked it up. I like the fact that majority of the parts are local to the Northwest.

Aero Precision upper and lower with mil spec tube
Black Hole Weaponry Polygonal (P3) barrel
Daniel Defense trigger group
Magpul furniture
YHM folding BUIS set (not pictured)

Going to the range tomorrow to get it sighted in with the new sights and see what all the hoopla is about the polygonal barrels. Not my pictures but pictures from the sale ad.

WTH is a polygonal barrel? Aero and DD is good stuff, should be a good rifle.

Same concept used in Glock barrels, and most H&K's, too.

That looks like a nice build. I look forward to the range report.
