OK, now that I have a few minutes I can talk a bit more about my new upper from Bison Armory
It's an 18" model (already had a 16") in 6.8 SPC. The receiver is from Tactical Machining and the hand guard is the T9 from Midwest Industries. Flash hider is a VC301 from Vltor. Flip-Up sights are both Yankee Hill and are very, very nice.
Last and not least is the dead sexy chrome bolt carrier from Young Manufacturing. I LOVE the way it looks. It's absolutely stunning.
I'm taking her out tomorrow for her first run. I barely have 30 rounds to my name, so it won't be a long run, but it should be fun nonetheless. I'll also be playing with some other toys which will get a full write up later.
