I bought a 243LBC upper from Ben and it's a tack driver. Ben is a great guy to deal with and a darn good machinist too. Best of luck with your sale buddy.
 
What is the difference between it and the 6.5grendel ? Is it something about the throat
 
Alexander Arms held the patent for a long time. Les Baer made the same thing to open up more options. The throat is probably different ( I don’t have a Grendel print to compare). Essentially they are the same as far as headspace and cartridge and chamber dimensions. It shoots factory Grendel ammo. If you have Grendel dies and such, you already have all you need.
 
Not sure. There is a lot of debate about that. I headspaced the barrel with the AA bolt it comes with. It’s face depth is .136.
