Buy FN 15 DMR3 – Precision 5.56 NATO Rifle

Buy FN 15 DMR3 and experience enhanced accuracy, reduced recoil, and superior shot-to-shot recovery in a premium-duty rifle built for precision shooting. The FN 15 DMR3 is engineered around an 18-inch hybrid-profile barrel, a rifle-length gas system, a Geissele two-stage G2S trigger, and a SureFire ProComp muzzle brake—working together to significantly reduce recoil impulse and muzzle rise while allowing precise trigger control.

At the core of the FN 15 DMR3 is FN’s cold hammer–forged, 18-inch chrome-lined barrel with a 1:8 twist rate. Manufactured from FN’s proprietary “machine gun barrel” steel, the hybrid profile delivers exceptional stiffness and heat absorption for accurate, high-volume firing. Chrome lining and hammer forging ensure extended barrel life and consistent performance under demanding conditions.

Designed for reliability and durability, the rifle features a fully free-floated Hodge Defense wedge-lock handguard, a low-profile pinned gas block, and an HP/MPI-tested bolt paired with an M16-style bolt carrier group. The FN 15 DMR3 is available in matte black anodized, factory Cerakote Flat Dark Earth (FDE), or tungsten gray finishes, complete with FN’s signature grip, buttstock, and magazine.
