If LMT's standard bolt is the infantryman of the gun industry, then the enhanced bolt is the delta operator.  This bolt was designed to function effectively in full-auto, suppressed, and short barrel weapon systems, and it is made of materials far more durable than your standard fare.  Quite simply, it’s the best possible upgrade for your rifle to increase reliability and functionality.

The LMT® Enhanced Bolt provides the following:

  • 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
