Radical Firearms, RF-15, 16 in, 300BLK (FDE)

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 Rem / 5.56 NATO pairs a 16" barrel with a 1:7" twist rate and a 15" RPR M-LOK handguard to deliver a balance of downrange stability and accessory flexibility. Finished in black anodize with FDE B5-style pistol grip and B5 stock, this AR-pattern rifle ships with one 30-round magazine and is set up for training, target work, and modular builds where common AR parts and optics are desired.

Key Features

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

• Barrel / Twist: 16" barrel with 1:7" twist — stabilizes a wide range of bullet weights for accuracy at varied distances.

• Handguard: 15" RPR rail with M-LOK slots — free-float compatibility for accessories and improved barrel harmonics.

• Finish: Black anodized receiver and components for corrosion resistance and subdued appearance.

• Furniture: FDE 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 and pattern — accepts common AR optics, triggers, and aftermarket parts.

• Use: Built for range training, modular accessory builds, and general-purpose AR shooting.

Why It Stands Out

This RF-15 combines a heavy-utility 1:7" twist/16" barrel combo with a long M-LOK rail and common AR ergonomics—giving shooters a stable, upgrade-friendly platform that handles a broad spectrum of loads and aftermarket options. The FDE B5 furniture offers a comfortable, familiar interface while the free-float RPR handguard keeps the rifle modular and accessory-ready.

Perfect For

• Range shooters and trainers running drills and accuracy work

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

• Hunters and varmint shooters using .223/5.56 where appropriate and legal

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