An apparatus and methods are provided for a bolt assembly for optimizing the operation of a direct gas operated firearm. The bolt assembly comprises a bolt having a forward recess surrounded by multiple lugs and a side recess. The lugs have a rear angle to reinforce the bolt while the bolt has an increased diameter to prevent a thin web from becoming a crack initiation point that reduces the life of the bolt. An extractor is pivotally mounted in the side recess by way of an extractor pin. The extractor includes an upper surface that is rounded in a circumferential direction to match a curvature of an exterior surface of the bolt. A claw portion of the extractor is spring biased into the forward recess. The extractor includes a lug extending along the upper surface above the claw portion. The extractor pin is configured to loosely seat within the bolt.
