Blue Line Solutions JRC45G3-TB/BL 45 ACP 17" Threaded Barrel

The Blue Line Solutions JRC45G3-TB/BL transforms standard pistol platforms into precision carbine systems with its 17-inch threaded barrel configuration. This 45 ACP conversion system delivers enhanced accuracy and velocity while maintaining the familiar manual of arms from the original pistol platform.

What Makes This Different

Unlike traditional carbine conversions that require permanent modifications, the JRC45G3-TB/BL utilizes a drop-in design that preserves the host firearm's original configuration. The 17-inch cold hammer-forged barrel increases muzzle velocity by approximately 200-300 fps over standard pistol lengths, while the threaded muzzle accepts suppressors and muzzle devices with standard 5/8x24 TPI threading. The M-LOK forend provides 360-degree accessory mounting capability without adding unnecessary bulk.

Key Features

• 17-inch threaded barrel with 5/8x24 TPI threading for suppressor compatibility
• M-LOK forend with multiple attachment points for accessories and optics
• Cold hammer-forged barrel construction for enhanced durability and accuracy
• Drop-in installation requiring no permanent modifications to host firearm
• Increased muzzle velocity over standard pistol barrel lengths
• Compatible with standard 45 ACP ammunition and magazines
• Integrated Picatinny rail sections for optics mounting

The extended barrel length significantly improves ballistic performance, particularly with heavier 45 ACP loads where the additional barrel time allows for more complete powder burn. This configuration excels in competitive shooting disciplines, tactical applications, and situations requiring enhanced accuracy at extended ranges. The threaded barrel accommodates sound suppressors for reduced noise signature, while the M-LOK forend accepts bipods, lights, and other tactical accessories.

Technical Specs

This conversion system represents a cost-effective alternative to purchasing a dedicated pistol caliber carbine while maintaining the versatility of the original platform. The combination of increased barrel length, suppressor capability, and modular accessory mounting creates a highly adaptable system for multiple shooting disciplines.
