American Composites Manufacturers Association The American Composites Manufacturers Association (ACMA) is the world’s largest composites industry trade group, driven to make composites the sustainable material of preference. The Microfibre Consortium (TMC) facilitates the development of practical solutions for the textile industry to minimize fiber fragmentation and release to the environment from textile manufacturing and product life cycle.

The proprietary, multi-layer carbon fiber and ceramic composite technology applies the concept of thermal inertia to expedite heat transfer from the barrel bore to improve overall performance. The ceramic and carbon fiber composite layers are applied in a proprietary process, and finished barrels are returned to the firearms manufacturer for incorporation into the final product.
