VASCAR2 Wrote:If your referring to the BCA 6.5 Grendel barrels they are SAAMI spec chamber. The type II refers to .136 bolt which BHW uses to describe .136 bolt and Type I is .125 7.62X39 bolt. Many manufactures use Type II nomenclature to indicate .136 bolt which is not to be confused with Grendel II chamber used by Satern/Liberty. Grendel II chamber uses traditional lead/throat with a long free bore whereas SAAMI 6.5 Grendel uses a compund throat and .300 neck.
now that's good to know. it was not plainly laid out in their description about the chamber.
