The Radical Firearms 10.5″ HBAR AR pistol, chambered in 7.62x39mm, provides a robust and compact platform engineered for reliable performance. This configuration integrates MIL-STD compliant upper and lower receivers with a precision 10.5-inch Heavy Barrel (HBAR) and a 10-inch Radical Rail System (RPR) free-float handguard.
Key Features
Construction & Foundation
- Utilizes MIL-STD (Military Standard) compliant upper and lower receivers, establishing a robust and standardized foundation for consistent component interchangeability and operational integrity.
- Precision machining ensures optimal fitment and structural stability, critical for maintaining zero and enduring operational demands.
Barrel & Ballistics
- The 10.5-inch HBAR (Heavy Barrel) profile contributes to increased rigidity, which enhances inherent accuracy and mitigates point-of-impact shift during sustained firing sequences.
- Chambered in 7.62x39mm, this pistol is optimized for a widely available and potent cartridge, delivering substantial terminal performance from a compact platform.
Rail System Integration
- Equipped with a 10-inch RPR (Radical Rail System) free-float handguard. This design prevents contact pressure on the barrel, which can adversely affect harmonics and accuracy.
- The RPR system also effectively dissipates barrel heat, preserving hand comfort and grip stability during extended use. Its integrated M-LOK or similar accessory interfaces accommodate diverse accessory configurations for mission-specific utility.
Reliability & Performance
- Engineered for consistent cycling and reliable operation with standard 7.62x39mm ammunition, ensuring functional integrity in dynamic environments.
- The combination of the HBAR and free-float rail system works to stabilize the projectile and minimize external influences on accuracy potential.
