it's possible to go too far and create a condition where the rifle could fire when the safety is released.
I purchased an '03 from CMP that had this problem. You had to pull the striker back slightly to engage the safety.
BIG PROBLEM. If you pulled the trigger with the safety engaged, nothing happened. BUT if you - THEN TURNED THE SAFETY OFF - the weapon would immediately fire!
I returned the weapon and CMP fixed the problem.
