@ beltfed: Their website states the CARRIER is MPI, not the bolt.
@trinimon: There aren't any rejectable defects on my DD part - it's eminently usable - just not as well made as the Stag part I compared it to.
Forgot to mention - both the Stag and DD bolts came with black Crane o-rings already installed.
What about the part on the carrier where the finish didn't take? Wouldn't that comply? Even if it was, would you have to go through DD yourself or through your authorized dealer?
