Now available, the long-awaited Carbon 50 308. By using a high percentage of carbon fiber strands combined with high temp polymers, our Carbon 50 composite lowers are in a league by themselves. After milling out the Fire Control pocket, the 308 weighs in at a mere 5.6 oz. resulting in a 20% weight savings and a stiffer, stronger frame ensuring a lighter performing rifle. A very limited Supply is available.
Key enhancements include:
- Extended upper fire control box sections.
- Upper left magazine well box section.
- Webbed magazine wells L & R side (matched for MagPul) magazines.
- Extended bolt release roll pin posts.
- New JMT Gen2 logo markings.
- DPMS Compliant

PERSONAL DEFENSE AND PROTECTION
How you decide to defend and protect yourself and your family is a personal matter. No one wishes to experience a personal breach of your safety or a home invasion but it does happen. The mission at JMT is to give you the assurance in a product you can trust.
The operations left to be completed to complete your JMT .308 80% lower are as follows: fire control group, trigger pin, hammer pin, trigger slot and the safety selector hole. This is a not an FFL item. This is not a complete receiver and still requires machining to be done.
This item cannot be shipped or sold out of the United States.
