FN FN15 DMR3 5.56x45mm 18in 30+1 Tungsten Gray
About this product
The FN FN15 DMR3 is a purpose-built precision AR-style rifle configured for accurate, repeatable performance at extended ranges. It combines an 18-inch hammer-forged, chrome-lined hybrid barrel with a rifle-length gas system and a two-stage Geissele trigger to support controlled, consistent shot-to-shot recovery. The platform includes a free-floated Hodge Defense handguard, pinned low-profile gas block, M16-style bolt carrier group, and a SureFire ProComp muzzle device to manage recoil impulse and muzzle rise.
