Radical Firearms, RF-15, Semi-Automatic, AR, 223/556 (Black/Coyote)

Radical Firearms RF-15 — .223 Rem / 5.56 NATO, 16" 1:7" Twist

Versatile, accurate AR — built for repeatable performance and modular customization.

The Radical Firearms RF-15 in .223 Remington / 5.56 NATO pairs a 16" barrel with a 1:7" twist and a 15" RPR M-LOK handguard to deliver downrange stability and accessory flexibility. Finished in black anodize and fitted with Coyote Brown B5-style pistol grip and B5 stock, this RF-15 ships with one 30-round magazine and is set up for training, target work, and modular builds using common AR parts and optics.

Key Features

• Caliber: .223 Remington / 5.56 NATO — versatile, widely available centerfire cartridge.

• Barrel / Twist: 16" barrel with 1:7" twist — stabilizes heavier bullets for extended-range accuracy.

• Handguard: 15" RPR free-float handguard with M-LOK slots for lights, grips, and accessories.

• Finish: Black anodized receiver and components for corrosion resistance and a subdued tactical look.

• Furniture: Coyote Brown B5-style pistol grip and B5 minimalist stock for modern ergonomics and lightweight handling.

• Magazine: Includes one 30-round magazine (verify local capacity restrictions).

• Controls / Pattern: Standard AR-15 controls — accepts common AR optics, triggers, and aftermarket parts.

• Use: Built for training, accuracy work, and modular accessory builds.

Why It Stands Out

This RF-15 mixes a performance-focused 1:7" twist/16" barrel with a long M-LOK rail and common AR ergonomics—giving shooters a stable, upgrade-ready platform that handles a wide spectrum of loads and aftermarket options. The Coyote Brown B5 furniture adds a durable, comfortable interface while the free-float RPR handguard keeps the rifle modular and accurate under accessory loads.

Perfect For

• Range shooters and trainers running drills and precision work

• Builders who want an AR platform ready for optics, triggers, and accessories

• Hunters and varmint shooters using heavier-for-caliber bullets where appropriate

• Shooters who prefer a reliable, upgradable AR with modern ergonomics and a long M-LOK rail
