Radical Firearms RF-15, 5.56/.223 (Black)

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

Accurate, modular, and mission-ready — SOCOM contour performance with mid-length smoothness.

The Radical Firearms RF-15 in .223 Rem / 5.56 NATO pairs a 16" SOCOM-contour barrel with a 1:7" twist and a mid-length gas system to deliver stable ballistics and a smooth recoil impulse across a wide range of loads. Built on a black-anodized receiver set with a 15" RPR free-float M-LOK handguard and fitted with B5-style grip and stock, this rifle ships with one 30-round magazine and is ready for training, range work, and modular upgrades.

Key Features

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

• Barrel: 16" SOCOM-contour barrel for balanced weight and heat dissipation.

• Twist / Accuracy: 1:7" twist — stabilizes heavier-for-caliber bullets for extended-range accuracy.

• Gas System: Mid-length gas system for smoother operation and reduced recoil impulse.

• Handguard: 15" RPR free-float M-LOK handguard — long accessory real estate without affecting barrel harmonics.

• Muzzle Device: A2 flash hider standard for low-profile muzzle control.

• Finish: Black anodized receivers and components for corrosion resistance.

• Furniture: 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.

Why It Stands Out

Combines a SOCOM-contour 16" barrel and mid-length gas tuning for a controllable shooting experience with a 1:7" twist that broadens load compatibility. The long free-float M-LOK rail keeps the rifle modular and upgrade-friendly while B5 furniture gives comfortable handling for extended sessions.

Perfect For

• Range and training shooters who want a smooth-shooting, accurate AR platform

• Builders and modifiers looking for a stable, upgradeable 16" AR host

• Hunters and varmint shooters using heavier-for-caliber projectiles where legal

• Shooters who value a balanced rifle with long M-LOK real estate for optics and accessories
