Semi-Auto Piston 6.8 SPC BCG

Details

Semi-auto piston 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
