Everything on a proper Mk136 bolt is the same as any other .223 bolt except for the extractor (WARNING - some "Grendel" bolts that are marked as .136 bolt face DO NOT take a standard firing pin - too long. You would have to measure your bolt overall length).
JP and one other company sells just the extractor, though you are probably better off getting a group buy bolt to keep as a spare.
