I'm doing the same. Waiting for an Ambi 18" CHF chrome-lined barrel in DDC.
I don't know if the weight measurements online are correct, but it looks like the strato match version with the cut rifled barrel is significantly heavier. 7.8 pounds vs 9.4 pounds in the 18" versions.
Either way, it seems like a great middle ground between a 5.56 DMR and a large frame 6.5 creedmoor. I already have both of those, might as well fill the gap in my lineup
