The FN 15 DMR3 delivers precision shooting capabilities in a versatile semi-automatic platform chambered in 5.56x45mm NATO. This designated marksman rifle bridges the gap between standard carbines and dedicated precision rifles, offering enhanced accuracy for competitive shooting and tactical applications.

What Makes This Different

The 18-inch cold hammer-forged barrel provides superior accuracy compared to standard 16-inch carbine barrels, extending effective range while maintaining manageable overall length. FN's manufacturing expertise ensures consistent sub-MOA potential with quality ammunition. The free-floating handguard eliminates barrel contact that can affect precision, while the enhanced trigger group delivers crisp, consistent break characteristics.

  • Free-floating M-LOK handguard with full-length Picatinny top rail

Field testing demonstrates consistent 1-2 MOA accuracy with match-grade ammunition, making this rifle suitable for precision competitions, varmint hunting, and designated marksman roles. The longer barrel increases muzzle velocity by approximately 100-150 fps over carbine-length barrels, improving terminal ballistics at extended ranges. Weather-resistant finishes and proven direct impingement operating system ensure reliable function in adverse conditions.
