Abstract
A bolt assembly for a direct gas firearm includes a plurality of sealing rings. In an embodiment, there are three rings with ring gaps cut at about a 45 degree angle and the middle ring is flipped so that the angle of the gap of the middle ring is approximately 90 degrees from the angle of the gap of the two outer rings. In an embodiment, the angle of the ring gap of at least one of the plurality of sealing rings is between 0 and 90 degrees and the ring is configured so that the ring gap is minimized once the ring is installed.
