I just built one with a black hole wesponry slim contour 16" and a Midwest ask keymod 12" rail with a magpul ctr stock. It's around 6.25 pounds but they make a slimmer barrel than mine. Still working on loads but it's shot some 1/2 moa groups with 75g hornady btsp's over ar comp. I really like it and have been carrying it everywhere with me. I hope to try a few more loads with 8208 tomorrow.
