Conceived as MantaRails in 2009 to solve the problem of loose weapon pressure pads, Manta Defense now manufactures proprietary, heat-mitigating firearm accessories in-house at its New Philadelphia, Ohio facility. Its products are standard issue on two Marine Corps programs, including the M27 Infantry Automatic Rifle, and are fielded by militaries around the world. Manta says its materials are designed to protect operators and gear from extreme heat while managing wires and switches without permanently altering a weapon.
