SAAMI Grendel Barrel Makers?

[VASCAR2]

Blame Black Hole Weaponry, BHW sold 264 LBC barrels chambered to use 7.62X39 bolts with a bolt face Depth of .125. Later BHW chambered 264 LBC barrels chambered to use 6.5 Grendel bolts with .136 bolt face Depth. To alleviate confusion BHW designsted barrels chambered to use .125 X39 bolts as Type I, barrels chambered to use .136 bolt face 6.5 Grendel bolts as Type II. Other manufactures and vendors have started to identify their barrels as Type II if they are chambered to use 6.5/Grendel bolts with .136 bolt.

If this isn’t bad enough Satern/Liberty released a chamber called Grendel II which also shoots 6.5 Grendel ammunition.
