F1 Firearms King FDR .223 Wylde 16in Black Semi-Automatic Modern Sporting Rifle

The F1 Firearms King FDR .223 Wylde Modern Sporting Rifle is engineered for shooters who demand top-tier performance, reliability, and modularity. Manufactured in Texas by F-1 Firearms using over 90% in-house machined components, the King FDR platform sets a new standard for precision, durability, and consistency. Whether you’re a competitive marksman, tactical operator, or weekend plinker, this rifle delivers unmatched function and accuracy.

Precision .223 Wylde Chambering

Chambered in .223 Wylde, the King FDR’s 16-inch stainless steel barrel features a 1:8 twist rate optimized to stabilize both .223 Remington and 5.56 NATO ammunition. The .223 Wylde chamber offers the best of both worlds: the tight tolerances of .223 Remington for exceptional accuracy and the robust pressure handling of 5.56 NATO for enhanced versatility. Shooters can confidently swap between ammo types without sacrificing point-of-impact or reliability.

Premium Barrel and Muzzle Device

The 16-inch barrel is precision rifled from high-grade stainless steel and finished with Type III hard coat black anodizing for corrosion resistance and a sleek matte appearance. The A2 flash hider reduces muzzle flash signature, allowing for faster target reacquisition in low-light or rapid-fire scenarios. With a mid-length gas system, felt recoil is softened and gas blowback is minimized, keeping the shooter comfortable and focused.

Free-Float M-Lok Handguard

Equipped with a 13-inch F-1 Firearms M-Lok free-float handguard, the King FDR offers an unobstructed barrel profile for consistent harmonics and accuracy. The lightweight, aircraft-grade aluminum handguard features M-Lok slots along three sides, providing ample attachment points for accessories such as tactical lights, lasers, foregrips, and bipods. The continuous top Picatinny rail ensures co-witnessing of iron sights or seamless optic integration.

In-House Forged Upper and Lower Receivers

F-1 Firearms maintains strict QC by forging and machining over 90% of each receiver in-house. The upper and lower are forged from 7075-T6 aluminum and treated with Type III hard coat anodizing to withstand harsh environments and heavy use. The tight-tolerance fitment between receivers minimizes play and ensures consistent bolt lockup for long-term accuracy retention.

Black Nitride Bolt Carrier Group

The durable bolt carrier group (BCG) is finished with black nitride for exceptional wear resistance, lubricity, and corrosion protection. Each BC is magnetic particle inspected and headspace checked to military specifications. The enhanced coating promotes reliable cycling under high-round counts and adverse conditions.

Mil-Spec Controls and Ergonomics

The King FDR includes mil-spec trigger, stock, pistol grip, and charging handle. The single-stage, Mil-Spec trigger delivers a crisp, clean break with minimal take-up. The adjustable Mil-Spec carbine stock provides six positions of length-of-pull adjustment, catering to shooters of all builds and gear layers. The ergonomic polymer pistol grip features textured surfaces for secure handling, even with gloves or wet hands.

Optics-Ready and Customizable

With no fixed sights installed, the King FDR leaves you free to tailor your optic setup: red dots, magnified scopes, holographics, or night-vision devices can all be mounted directly to the Picatinny rail. The rifle’s modular design accepts standard AR-15 components, allowing the addition of backup iron sights, ambidextrous controls, or custom hand stops.

Quality and Compliance

F-1 Firearms King FDR rifles are manufactured under strict quality control protocols. Each rifle undergoes a function test and inspection before leaving the factory.
