The fault you refer to was possible with the Mk 3 action. This is a Mk 2, and is a completely different action that does not have the issue. In addition, during service there were modifications made to the rifle to prevent improper assembly of the bolt. A Mk 3 bolt was also tested by Forgotten Weapons on Youtube and it was shown that an out of battery detonation, while bad, would not blow up the gun or substantially injure the shooter. The bolt was retained by the bolt stop and although it sheared off a couple lugs the damage was essentially nothing compared to the ridiculous claims of old.
