FN 36-100669: Enhanced accuracy from the FN 15 DMR3 enabling you to keep on target for faster shot-to-shot recovery is achieved from the combination of the 18-inch hybrid profile barrel, rifle-length gas system, Geissele two-stage G2S trigger and SureFire ProComp muzzle brake that greatly reduces both recoil impulse and muzzle rise and that allows precise and accurate trigger control. At the heart of the DMR3 is the FN hammer forged, 18-inch, 1:8 twist, chrome lined barrel. The barrel has FNs Hybrid profile that provides the stiffness and heat absorption needed for accurate, high volume shooting. Long barrel life is achieved by hammer forging from FNs proprietary machine gun barrel steel and chrome lining. The rifle also features a fully free-floated Hodge Defense-designed wedge lock handguard, a low-profile gas block that is pinned to the barrel, HP/MPI-tested and certified bolt and M16-style bolt carrier group for complete reliability and performance.
