Pro-level ergonomics: Enhanced magazine well geometry, flared magwell, and clean control placement reduce fumbles and speed up reps under timer or stress. Duty-tough finish: Cerakote® Black resists abrasion, solvents, sweat, and weather, maintaining a professional, low-glare appearance. Handguard included: The slim 15.5" M-LOK® free-float rail maximizes sight radius and accessory real estate while preserving barrel harmonics for better precision. Premium components in the box: The Radian Talon™ safety (45°/90° configurable) and hammer pin simplify parts sourcing and align with Radian’s quality standard.
