The FN 15 Tac3 5.56x45mm NATO carbine is engineered for consistent performance and adaptability. Built upon a MIL-SPEC foundation, this platform integrates features critical for demanding applications, from competitive shooting to personal defense. Its design prioritizes reliability and user-interface optimization, delivering a precision instrument for critical engagement scenarios.
Key Features
Barrel & Accuracy System
At its core, the Tac3 features a 16-inch, chrome-lined, cold hammer-forged barrel crafted from FN proprietary steel. This construction method significantly enhances barrel life and maintains accuracy under sustained fire. The barrel is fully free-floated within the handguard, mitigating external pressure points that can induce deflection and contributing to a stable, repeatable shooting platform.
Handguard & Accessory Integration
The rifle integrates a Hodge Defense-designed wedge lock handguard, known for its rigidity and secure attachment. This robust handguard provides a continuous 12 o’clock Picatinny rail, optimizing mounting solutions for tactical optics and iron sights. Additionally, multiple M-LOK attachment points are positioned along the handguard, allowing users to configure firearm accessories such as lights, lasers, and vertical grips precisely to individual operational requirements.
Internal Components & Reliability
Internal components include an HP/MPI-tested and certified bolt, paired with an M16-style bolt carrier group. This configuration, combined with a mid-length gas system and an H buffer, ensures reliable cycling across a range of operational conditions and ammunition types, mitigating common AR platform malfunctions.
Ergonomics & Controls
Operational efficiency is enhanced by ambidextrous Radian controls, including the charging handle and selector, providing intuitive and efficient manipulation for all users, regardless of dominant hand. The rifle is equipped with an FN custom 6-position collapsible buttstock and an FN pistol grip, ensuring comfortable and consistent control during dynamic engagements. An FN magazine is included to complete the ready-to-deploy package. The gray anodized receiver group offers a distinct, functional aesthetic contrast to the black furniture.
