  1. The bullet is small enough in mass that there's very little felt recoil, most felt "recoil" isn't even true recoil but transfer of momentum from the bolt to the receiver. By slamming the countermass forward to make up for the slamming of the bolt to the rear, you get less aim shift from the cycle. In competition ARs the same effect is acomplished by removing mass from the carrier and purposefully "undergassing" the system. But this makes them less reliable in combat conditions.
