Type 2 bolt face depth .136
Type 1 bolt face depth .125
THIS^^^^^^
Type 1 and Type 2 only refer to how the chamber is cut for bolt face depth. SAMMI has no spec for bolts. Type 1, officially referred to around here as Mk125, and Type 2 is Mk136. The .136 bolt face is the final and correct bolt face for the Grendel as designed.
