    Interesting.
    The way I see it, as the BCG in an AR moves rearward, there are 4 significant milestones. #1 the point where ejection occurs, #2 the point where failure to feed would happen if rearward movement stopped, #3 the point where failure to lock back would happen, and #4 the point where the reciprocating mass (BCG and buffer) hit the RE and stop, contributing to recoil.
    This system gives more distance between #3 and #4, ensuring reliability while giving more time for the spring to slow down the reciprocating mass prior to #4. This should mean less recoil, I would guess. It probably shoots like a gun with the adjustable gas block turned down to the ragged edge while still being reliable.
    I'm sure there is more to it but that seems pretty cool. It kind of reminds me of the ultimax 100 LMG, which is designed with a "constant recoil" where the reciprocating mass never hits the rear, it is always under spring power.
