  A:

  No it is not Joseph. From Phase 5 Directly [***There has been a lot of talk about the pros and cons of staking the gas key on the carrier. Here is our opinion and why we do not stake keys. The US Mil Spec. assembly drawing requires the carrier key to be staked. Contrary to some popular opinions staking does not “SEAL” the gas key. Staking keeps the screws from backing out. Period].
