Well... I thought I was done building AR's... that was until a friend of mine decided to let go a new in the wrap Krieger 18" barrel from Compass Lake Engineering... he bought it back in 2014 and it has sat in the box ever since.
Seeing as I just picked up my second AEM5, might as well start on another Mk12 build. There's just something about an 18" AR rifle that I love. I have a few with various barrels, Ballistic Advantage, Douglas, Criterion, and now... a Krieger.
This came with a matched bolt "69" witch is etched on the bolt and stamped on the barrel. Compass Lake isn't doing these any more so get get one NIB from 2014 was a damn good find IMO. I even have the original packaging, box, and invoice.
