It should take a mil spec length fireing pin.
Toolcraft at one time when they first got into the grendel had complete bcg's that the fireing pin was of diffrent length because they didn't make their grendel bolts too spec length.
From what I have seen this has been fixed.
Long as your bolt has a .136 bolt face depth it will use a mil spec length fireing pin.
