Lewis Machine & Tool (LMT) AR-15 5.56 Enhanced Full Auto Bolt Carrier Group

If their standard bolt carrier group is the infantryman of the gun industry, then our enhanced BCG is the delta operator.  This carrier group 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.

Behold the laundry list of enhancements our design brings to the table:

Carrier:

• Altered cam path for longer dwell time and more robust extraction
• Modified gas hole improves gas flow across the bolt’s tail
• Additional gas ports on right side and modified orientation to improve gas flowing through the ejection port, and not into your face
• Relief grooves added to the top and bottom to channel debris and maintain fluid movement

Bolt:

• 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

Specifications:

• Caliber: .204 Ru, .300 BLK, 5.56×45
• Operating Method: Direct Impingement
• Bolt or BCG: Bolt Carrier Group
• Weight: 11.3 oz
