LMT Enhanced Full-Auto M16 Bolt Carrier Group
This Lewis Machine and Tool bolt carrier group is a full auto rated, M16 cut carrier designed for long term durability and reliability.
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
Enhanced Full Auto Bolt Carrier Group, 5.56×45 (.223)

Product speaks for itself if you know what you want, simple as that. What gets 5 starts day in and day out is Rooftop Defense as a company and Sol and Abby as great people who care about the products, their business and all their customers. Rooftop is #1 go to for everything. If they dont have it, before looking anywhere else, I message Sol and let’s me know if they will get that product and I usually wait. Im loyal when it comes to good people doing good business. Rooftop is top tier company all around.

The LMT Enhanced BCG Actually Works!
Installed this in a heavily suppressed MK18 and the difference was immediate—virtually no gas to the face, smoother operation, and flawless reliability.
This is not a subtle upgrade you have to convince yourself you notice. It genuinely improves the shooting experience on a short, suppressed rifle. Expensive, but absolutely worth it.
Rooftop Defense was excellent as always. Fast shipping and great service.
