Fortis Manufacturing's aim is to provide "Operator" needed strength with exceptional design and aesthetics at an affordable price. We are passionate about bringing the best AR15/M16 products to the market. Fortis Manufacturing, Inc. (FMI), utilizes only the highest quality materials available and machining that is second to none. Every product designed by FMI™ undergoes a strenuous testing and evaluation period with a diverse group of select professionals. Feedback is collected at the end of the testing period and evaluated. If design changes are warranted, further samples are constructed and sent back out for further testing. It is not until all issues have been resolved and all feedback has been addressed that a product is considered ready for production. It is this philosophy that ensures each product will meet or exceed the heavy demands of the professionals who use them.
