Trusted by the US government to produce barrels for our modern warriors and that same level of quality and expertise is now available to you. FN utilizes the same proprietary high grade Chrome Moly Vanadium steel used in FN machine gun barrels produced to handle the punishment of sustained full auto fire. Each barrel is High Pressure Tested and Magnetic Particle Inspected to ensure that it is free of micro-stresses or flaws resulting in consistent, quality barrels.
