Gun Barrels

FN makes the finest gun barrels in the world. Why?


FN has more than 125 years of experience designing and manufacturing firearms, first through our parent company, FN, and in the U.S. since 1981. Throughout that period, FN America and FN Herstal have together designed and produced a number of the most iconic military firearms in the world, including the FN MAG®, adopted by the U.S. Army as the M240; the FN MINIMI®, adopted by the U.S. Army as the M249 Squad Automatic Weapon (SAW); the FN M3M™, adopted by the U.S. Navy as the GAU-21; the FN SCAR®-L, adopted by U.S. Special Forces as the MK16; and the FN SCAR®-H, adopted by U.S. Special Forces as the MK17. FN-designed firearms are in use by military and law enforcement personnel in 90 countries around the world.

Today, FN produces a wide range of small arms for the U.S. military: M4/M4A1 carbines, M16 rifles, MK19 grenade machine guns, and M249 SAWs, as well as the MK46, MK48, M240, M240C, M240D, M240E1, M240H, M240B, and M240L machine guns.

In addition to manufacturing for the U.S. military, FN also builds some of the finest handguns on the commercial market, including the FNX™ series of hammer-driven pistols and the newest FNS™ line of striker-fired pistols. We also manufacture our own barrels in any caliber a customer needs.


The technology used by FN in its barrel production process is simply unmatched. We use the latest in high-tech equipment, the most efficient and effective processes, as well as high-quality materials – all of which ensure our gun barrels are the most precise and long-lasting money can buy.

Our record speaks for itself as one of the largest suppliers of small arms to the U.S. military, forces known to demand the most innovative, reliable products available.

Quality Through Processes

By using the most advanced automated manufacturing processes, FN barrels are certain to be of the highest quality at the most efficient cost. Our hammer-forged, chrome-plated barrel is legendary in the firearms industry for its precise accuracy and long life. Our button-broached barrel is of such high quality, a breaking-in period is not required, and it will shoot accurately right out of the box.
