Full-auto bolt carrier group compatible with 6.8 SPC and .224 Valkyrie. Our 6.8 bolt is made to the same specifications as our 5.56 enhanced bolt and offers the same improvements:
- Built from a proprietary material that is not only stronger than the standard bolt but easier to clean as well
- Modified locking lugs provide flexibility and durability in dealing with high-pressure, overgassed loads
- ?Lobster tail? extractor utilizes two springs to allow stronger and more consistent extraction with drastically improved spring life
